A5 PROBLEM DEFINITION/BACKGROUND In 1991, the Texas Legislature passed the Texas Clean River Act (Senate Bill 818) in response to growing concerns that water resource issues were not being pursued in an integrated, systematic manner. The act requires that ongoing water quality assessments be conducted for each river basin in Texas, an approach that integrates water quality issues within the watershed. The CRP legislation mandates that “each river authority (or local governing entity) shall submit quality-assured data collected in the river basin to the commission.” “Quality-assured data” in the context of the legislation means “data that comply with commission rules for surface water quality monitoring programs, including rules governing the methods under which water samples are collected and analyzed and data from those samples are assessed and maintained.” This QAPP addresses the program developed between the Trinity River Authority and the TCEQ to carry out the activities mandated by the legislation. The QAPP was developed and will be implemented in accordance with provisions of the Quality Management Plan for the Clean Rivers Program (most recent version). The purpose of this QAPP is to clearly delineate TRA CRP QA policy, management structure, and procedures which will be used to implement the QA requirements necessary to verify and validate the surface water quality data collected. The QAPP is reviewed by the TCEQ to help ensure that data generated for the purposes described above are scientifically valid and legally defensible. This process will ensure that data collected under this QAPP and submitted to SWQMIS have been collected and managed in a way that guarantees its reliability and therefore can be used in water quality assessments and other programs deemed appropriate by the TCEQ. Project results will be used to support the achievement of Clean Rivers Program objectives as contained in the Clean Rivers Program Guidance and Reference Guide FY 2010 -2011. The Trinity River Authority recognizes that there exists, within the Trinity River basin, a great number of agencies performing routine water quality sampling for their own objectives outside of the Clean Rivers Program. Basin maps can be found in Appendix B. These agencies generate a wealth of data concerning Trinity River water quality. It is therefore the objective of this agency to seek to obtain data from existing programs in lieu of establishing a basin-wide CRP water quality sampling program. This avoids duplication of effort and fosters communication and sharing of data between basin water agencies. Towards this end, the TRA CRP will coordinate closely with local agencies conducting water quality sampling programs. Although the sampling conducted by the Within-Basin Participating Agencies (WBPAs) is quite comprehensive, the Main Stem of the Trinity River from Fort Worth to Oakwood was left relatively unsampled. TRA began monitoring this stretch of the river in-house in order to more completely monitor the basin. The participation of the Within-Basin Participating Agencies is strictly voluntary, and it is recognized by both the Trinity River Authority of Texas and the Texas Commission on Environmental Quality that the programs conducted by WBPAs exist for purposes independent of the Clean Rivers Program. At the same time, it is recognized that the CRP must generate data of a known quality in order for such data to be used by the TCEQ in a regulatory capacity. This QAPP details the standards which will be maintained in order to ensure quality data is being generated for and by this program. Procedures not directly specified as varying between sampling entities will hold true for all WBPAs and subcontractors. It is not the desire of the TRA CRP to dictate policy, only establish minimum criteria for acceptability of data under the Clean Rivers Program. Should WBPAs or the TRA Project Manager or the TCEQ CRP Project Manager determine that minimum criteria established by this QAPP are not being met for specific parameters, data generated concerning those parameters will not be submitted to TCEQ. WBPAs are under no obligation whatsoever to modify their current practices in order to comply with criteria herein set forth although failure to do so may result in data not being submitted to TCEQ. This QAPP will initially


address the routine water quality monitoring practices of the Tarrant Regional Water District, the Lake Livingston Project, the City of Arlington, the City of Dallas, the City of Fort Worth, the City of Grand Prairie, the City of Irving, and TRA’s In-House Monitoring; other WBPAs may be added at a later date in the form of amendments to this QAPP. It shall be the responsibility of the Project Manager of WBPAs or subcontractors employed by the Trinity River Authority to ensure that laboratories used maintain adequate quality controls as specified in this document. Towards the end of assuring that guidelines set forth in this QAPP are being met, the TRA CRP QAO shall conduct monitoring system audits on subcontractors and WBPAs. Such audits will be limited to activities generating data covered by this QAPP. Any non-compliance issues will be presented in writing to appropriate personnel. WBPAs are under no obligations to adopt suggested changes resulting from an audit. Failure to address compliance issues could however, invalidate some or all data being generated for the CRP. Such data, at the discretion of the TRA Project Manager, may be withheld from the TCEQ’s SWQMIS database.


A6 PROJECT/TASK DESCRIPTION Entities which will be collecting routine data include Tarrant Regional Water District, TRA’s Lake Livingston Project, the City of Arlington, the City of Dallas, the City of Fort Worth, the City of Irving, the City of Grand Prairie, and TRA’s Main Stem Monitoring. In all, this QAPP covers sampling activities at approximately 200 sites with a total of more than 70 different parameters. These parameters are sampled at various locations and frequencies (see Appendix B for a detailed list of routine monitoring stations and parameter groups to be monitored this fiscal year). See Appendix A for the project-related work plan tasks and schedule of deliverables for a description of work defined in this QAPP. See Appendix B for sampling design and monitoring pertaining to this QAPP. Amendments to the QAPP Revisions to the QAPP may be necessary to address incorrectly documented information or to reflect changes in project organization, tasks, schedules, objectives, and methods. Requests for amendments will be directed from the TRA Project Manager to the CRP Project Manager electronically. Amendments are effective immediately upon approval by the TRA Project Manager, the TRA QAO, the Laboratory, the CRP Project Manager, the CRP Lead QA Specialist, and the CRP Project QA Specialist. They will be incorporated into the QAPP by way of attachment and distributed to personnel on the distribution list by the TRA Project Manager. Special Project Appendices Projects requiring QAPP appendices will be planned in consultation with the TRA and the TCEQ Project Manager and TCEQ technical staff. Appendices will be written in an abbreviated format and will reference the Basin QAPP where appropriate. Appendices will be approved by the TRA Project Manager, the TRA QAO, the Laboratory Manager, the CRP Project Manager, the CRP Project QA Specialist, the CRP Lead QA Specialist and other TCEQ personnel as appropriate. Copies of approved QAPPs appendices will be distributed by the TRA to project participants before data collection activities commence.


A7 QUALITY OBJECTIVES AND CRITERIA The purpose of routine water quality monitoring is to collect surface water quality data needed for conducting water quality assessments in accordance with TCEQ’s Guidance for Assessing Texas Surface and Finished Drinking Water Quality Data. These water quality data, and data collected by other organizations (e.g., USGS, TCEQ, etc.), will be subsequently reconciled for use and assessed by the TCEQ. Parameters other than those needed for assessments (metals, diel monitoring, other nutrients and conventionals) will be collected by WBPAs and submitted to TCEQ under this QAPP. These parameters are collected due to the fact that the WBPAs have monitoring objectives outside of the Clean Rivers Program, such as watershed protection and permitting. Systematic watershed monitoring is defined by sampling that is planned for a short duration (1 to 2 years) and is designed to: screen waters that would not normally be included in the routine monitoring program, monitor at sites to check the water quality situation, and investigate areas of potential concern. Due to the limitations regarding these data (e.g., not temporally representative, limited number of samples, biological sampling does not meet the specimen vouchering requirements), the data will be used to determine whether any locations have values exceeding the TCEQ’s water quality criteria and/or screening levels (or in some cases values elevated above normal). The TRA will use this information to determine future monitoring priorities. These water quality data, and data collected by other organizations (e.g., USGS, TCEQ, etc.), will be subsequently reconciled for use and assessed by the TCEQ. The measurement performance specifications to support the project purpose for a minimum data set are specified in Tables A7.1 to A7.8 and in the text following. Ambient Water Reporting Limits (AWRLs) The AWRL establishes the reporting specification at or below which data for a parameter must be reported to be compared with freshwater screening criteria. The AWRLs specified in Tables A7.1 to A7.8 are the program-defined reporting specifications for each analyte and yield data acceptable for the TCEQ’s water quality assessment. A full listing of AWRLs can be found at http://www.tceq.state.tx.us/compliance/monitoring/crp/qa/index.html. The limit of quantitation is the minimum level, concentration, or quantity of a target variable (e.g., target analyte) that can be reported with a specified degree of confidence. The following requirements must be met in order to report results to the CRP:

• The laboratory’s LOQ for each analyte must be at or below the AWRL as a matter of routine practice

• The laboratory must demonstrate its ability to quantitate at its LOQ for each analyte by

running an LOQ check standard for each analytical batch of CRP Samples analyzed. Laboratory Measurement Quality Control Requirements and Acceptability Criteria are provided in Section B5 Precision Precision is the degree to which a set of observations or measurements of the same property, obtained under similar conditions, conform to themselves. It is a measure of agreement among replicate


measurements of the same property, under prescribed similar conditions, and is an indication of random error. Field splits are used to assess the variability of sample handling, preservation, and storage, as well as the analytical process, and are prepared by splitting samples in the field. Control limits for field splits are defined in Section B5. Laboratory precision is assessed by comparing replicate analyses of laboratory control samples in the sample matrix (e.g. deioinized water, sand, commercially available tissue)or sample/duplicate pairs in the case of bacterial analysis. Precision results are compared against measurement performance specifications and used during evaluation of analytical performance. Program-defined measurement performance specifications for precision are defined in Tables A7.1 to A7.8. Bias Bias is a statistical measurement of correctness and includes multiple components of systematic error. A measurement is considered unbiased when the value reported does not differ from the true value. Bias is determined through the analysis of laboratory control samples and LOQ Check Standards prepared with verified and known amounts of all target analytes in the sample matrix (e.g. deioinized water, sand, commercially available tissue) and by calculating percent recovery. Results are compared against measurement performance specifications and used during evaluation of analytical performance. Program-defined measurement performance specifications for bias are specified in Tables A7.1 to A7.8. Representativeness Site selection, the appropriate sampling regime, the sampling of all pertinent media according to TCEQ SOPs, and use of only approved analytical methods will assure that the measurement data represents the conditions at the site. Routine data collected under the Clean Rivers Program for water quality assessment are considered to be spatially and temporally representative of routine water quality conditions. Water Quality data are collected on a routine frequency and are separated by approximately even time intervals. At a minimum, samples are collected over at least two seasons (to include inter-seasonal variation) and over two years (to include inter-year variation) and includes some data collected during an index period (March 15- October 15). Although data may be collected during varying regimes of weather and flow, the data sets will not be biased toward unusual conditions of flow, runoff, or season. The goal for meeting total representation of the water body will be tempered by the potential funding for complete representativeness. Comparability Confidence in the comparability of routine data sets for this project and for water quality assessments is based on the commitment of project staff to use only approved sampling and analysis methods and QA/QC protocols in accordance with quality system requirements and as described in this QAPP and in TCEQ SOPs. Comparability is also guaranteed by reporting data in standard units, by using accepted rules for rounding figures, and by reporting data in a standard format as specified in the Data Management Plan Section B10.


Completeness The completeness of the data is basically a relationship of how much of the data is available for use compared to the total potential data. Ideally, 100% of the data should be available. However, the possibility of unavailable data due to accidents, insufficient sample volume, broken or lost samples, etc. is to be expected. Therefore, it will be a general goal of the project(s) that 90% data completion is achieved.

A8 SPECIAL TRAINING/CERTIFICATION All field personnel receive training in proper sampling and field analysis. Before actual sampling or field analysis occurs, they will demonstrate to the QA Officer (or designee) their ability to properly calibrate field equipment and perform field sampling and analysis procedures. Field personnel training is documented and retained in the personnel file and will be available during a monitoring systems audit. The requirements for Global Positioning System (GPS) certification are located in Section B10, Data Management. Contractors and subcontractors must ensure that laboratories analyzing samples under this QAPP meet the requirements contained in section 5.4.4 of the NELAC standards (concerning Review of Requests, Tenders and Contracts).

B1 SAMPLING PROCESS DESIGN See Appendix B for sampling process design information and monitoring tables associated with data collected under this QAPP.


B2 SAMPLING METHODS Field Sampling Procedures Field sampling will be conducted according to procedures documented in the TCEQ Surface Water Quality Monitoring Procedures Volume 1: Physical and Chemical Monitoring Methods for Water, Sediment, and Tissue, October 2008 (RG-415) and Volume 2: Methods for Collecting and Analyzing Biological Community and Habitat Data, June 2007 (RG-416). Additional aspects outlined in Section B below reflect specific requirements for sampling under the Clean Rivers Program and/or provide additional clarification. Sample Containers Sample containers (cubitainers) are purchased pre-cleaned for conventional parameters and are disposable. TRWD reuses all containers except bacteria sample bottles -- rigid plastic containers, nalgene, and glass containers are acid rinsed at the lab with the appropriate acid solution, rinsed with DI water, and air dried. Whirl-pak bags or sterile 100 mL plastic bacteria bottles are used for bacteriological samples and may have 1% sodium thiosulfate tablets added. Amber glass or plastic bottles or foil wrapped cubitainers are used routinely for chlorophyll samples. The sample containers for metals are new, certified glass or plastic bottles, or glass or plastic bottles cleaned and documented according to EPA method 1669. Certificates are maintained in a notebook by the TRA, WBPA, or by the laboratory depending on the source of the sample containers. Processes to Prevent Contamination Procedures outlined in the TCEQ Surface Water Quality Monitoring Procedures outline the necessary steps to prevent contamination of samples. These include: direct collection into sample containers, when possible; triple rinsing equipment such as buckets used for sample collection with ambient water or deionized water when the use of ambient water for rinsing is not feasible; clean sampling techniques for metals; and certified containers for organics. Field QC samples (identified in Section B5) are collected to verify that contamination has not occurred.

Matrix is water unless otherwise specified. All filtration is 0.45um unless otherwise specified. Preservation is performed in the field within 15 minutes of sample collection. *E.coli samples analyzed for LLP only by SM 9223-B (IDEXX Colilert) should always be processed as soon as possible and within 8 hours. When transport conditions necessitate delays in delivery longer than 6 hours, the holding time may be extended and samples must be processed as soon as possible and within 48 hours.


Documentation of Field Sampling Activities Field sampling activities are documented on field data sheets as presented in Appendix C. The following will be recorded for all visits as negotiated with each WBPA: 1. Station ID 2. Sampling Date 3. Location 4. Sampling depth 5. Sampling time 6. Sample collector’s name/signature 7. Values for all field parameters 8. Detailed observational data, including:

• water appearance • weather • biological activity • unusual odors • days since last significant rainfall • flow severity • flow estimation calculation or instantaneous flow from gage, flow meter, or weir • pertinent observations related to water quality or stream uses (e.g., exceptionally poor water

quality conditions/standards not met; stream uses such as swimming, boating, fishing, irrigation pumps, etc.)

• watershed or instream activities (events impacting water quality, e.g., bridge construction, livestock watering upstream, etc.)

• specific sample information (number of sediments grabs, type/number of fish in a tissue sample, etc.)

• missing parameters (i.e., when a scheduled parameter or group of parameters is not collected) Recording Data For the purposes of this section and subsequent sections, all field and laboratory personnel follow the basic rules for recording information as documented below: 1. Write legibly in indelible ink 2. Changes should be made by crossing out original entries with a single line, entering the

changes, and initialing and dating the corrections. 3. Close-out incomplete pages with an initialed and dated diagonal line. Sampling Method Requirements or Sampling Process Design Deficiencies, and Corrective Action Examples of sampling method requirements or sample design deficiencies include but are not limited to such things as inadequate sample volume due to spillage or container leaks, failure to preserve samples appropriately, contamination of a sample bottle during collection, storage temperature and holding time exceedance, sampling at the wrong site, etc. Any deviations from the QAPP and appropriate sampling procedures may invalidate resulting data and may require corrective action. Corrective action may include for samples to be discarded and re-collected. Deviations will be communicated from the WBPA or TRA field or laboratory staff to the WBPA or TRA Project


Managers. WBPA Project Managers will forward information about deviations to the TRA Project Manager. It is the responsibility of the TRA Project Manager, in consultation with the TRA QAO, to ensure that the actions and resolutions to the problems are documented and that records are maintained in accordance with this QAPP. In addition, these actions and resolutions will be conveyed to the CRP Project Manager both verbally and in writing in the project progress reports and by completion of a corrective action plan (CAP). The definition of and process for handling deficiencies and corrective action are defined in Section C1.


B3 SAMPLE HANDLING AND CUSTODY Sample Tracking Proper sample handling and custody procedures ensure the custody and integrity of samples beginning at the time of sampling and continuing through transport, sample receipt, preparation, and analysis. A sample is in custody if it is in actual physical possession or in a secured area that is restricted to authorized personnel. The Chain of Custody (COC) form is a record that documents the possession of the samples from the time of collection to receipt in the laboratory. The following information concerning the sample is recorded on the COC form (See Appendix C). The following list of items matches the COC forms in Appendix C as negotiated with each WBPA. 1. Date and time of collection 2. Site identification 3. Sample matrix 4. Number of containers 5. Preservative used 6. Was the sample filtered 7. Analyses required 8. Name of collector 9. Custody transfer signatures and dates and time of transfer 10. Bill of lading (if applicable) Sample Labeling Samples from the field are labeled on the container or on a label with an indelible marker as negotiated with each WBPA. Label information includes: 1. Site identification 2. Date and time of collection 3. Preservative added, if applicable 4. Designation of “field-filtered” as applicable 5. Sample type (i.e., analysis(es)) to be performed Sample Handling Field data sheets will be used by all participants to document field conditions and sample collection. Electronic data loggers may also be used for this purpose. Examples of field data sheets used by all WBPAs and subcontractors can be found in Appendix C. All samples are handled and transported under chain of custody forms from the sampling location to the laboratory. Chain of custody forms from all sampling entities can also be found in Appendix C. In some cases, a combined field data sheet and chain of custody form is used. Samples are collected by field crews using appropriate sampling methodologies, preserved with acidification or other appropriate preservatives if necessary (preservation requirements are documented on field data sheets and labels), placed in coolers packed with ice and delivered to laboratories within holding times. This basic methodology is followed by all sampling personnel. Except for the instances listed below, all samples are delivered to laboratories the same day they are collected.


Exceptions include:

1) TRWD Eastern Division non-E. coli samples which are driven to the lab the day after collection (E. coli is collected during specific sampling events and delivered to the lab on the same day within the 6 hour holding time);

2) City of Dallas metals which are delivered to the lab at the end of the month of sampling; and 3) On rare occasions when shipment of samples is required (LLP personnel ship samples to TRA

Central for analysis), samples will be packed in ice and shipped in coolers using express delivery.

Upon arrival at the laboratory, transfer of custody is documented on chain of custody forms, samples are placed in coolers and logged into the laboratories’ LIM Systems. Laboratory personnel accepting samples will confirm that samples were placed on ice, and that there is still ice remaining around sample containers, indicating that an attempt was made to maintain the temperature of the samples at 4oC. Samples which are required to be cooled but are not received on ice will not be analyzed. Sample Tracking Procedure Deficiencies and Corrective Action All deficiencies associated with chain-of-custody procedures as described in this QAPP are immediately reported to the TRA Project Manager. These include such items as delays in transfer, resulting in holding time violations; violations of sample preservation requirements; incomplete documentation, including signatures; possible tampering of samples; broken or spilled samples, etc. Deficiencies will be communicated from the WBPA or TRA field or laboratory staff to the WBPA or TRA Project Managers. WBPA Project Managers will forward information about deficiencies to the TRA Project Manager. The TRA Project Manager in consultation with the TRA QAO will determine if the procedural violation may have compromised the validity of the resulting data. Any failures that have reasonable potential to compromise data validity will invalidate data, and the sampling event should be repeated. The resolution of the situation will be reported to the TCEQ CRP Project Manager in the project progress report. Corrective Action Plans will be prepared by the Lead Organization QAO and submitted to TCEQ CRP Project Manager along with project progress report. The definition of and process for handling deficiencies and corrective action are defined in Section C1.


B4 ANALYTICAL METHODS The analytical methods, associated matrices, and performing laboratories are listed in Tables A7.1 to A7.8 of Section A7. The authority for analysis methodologies under the Clean Rivers Program is derived from the TSWQS (§§307.1 - 307.10) in that data generally are generated for comparison to those standards and/or criteria. The Standards state that “Procedures for laboratory analysis will be in accordance with the most recently published edition of Standard Methods for the Examination of Water and Wastewater, the latest version of the SWQM Procedures, Volume 1: Physical Methods for Water, Sediment, and Tissue, 40 CFR 136, or other reliable procedures acceptable to the Executive Director.” Laboratories collecting data under this QAPP are compliant with the NELAC standards. Copies of laboratory QMs and SOPs are available for review by the TCEQ. Standards Traceability All standards used in the field and laboratory are traceable to certified reference materials. Standards preparation is fully documented and maintained in a standards log book. Each documentation includes information concerning the standard identification, starting materials, including concentration, amount used and lot number; date prepared, expiration date and preparer’s initials/signature. The reagent bottle is labeled in a way that will trace the reagent back to preparation. Analytical Method Deficiencies and Corrective Actions Deficiencies in field and laboratory measurement systems involve, but are not limited to such things as instrument malfunctions, failures in calibration, blank contamination, quality control samples outside QAPP defined limits, etc. In many cases, the field technician or lab analyst will be able to correct the problem. If the problem is resolvable by the field technician or lab analyst, then they will document the problem on the field data sheet or laboratory record and complete the analysis. If the problem is not resolvable, then it is conveyed to the TRA or WBPA Laboratory Supervisor, who will make the determination and notify the TRA QAO. If the analytical system failure may compromise the sample results, the resulting data will not be reported to the TCEQ. The nature and disposition of the problem is reported on the data report which is sent to the TRA Project Manager. The TRA Project Manager will include this information in the CAP and submit with the Progress Report which is sent to the TCEQ CRP Project Manager. The definition of and process for handling deficiencies and corrective action are defined in Section C1. The TCEQ has determined that analyses associated with the qualifier codes “holding time exceedance”, “sample received unpreserved”, “estimated value”, etc... may have unacceptable measurement uncertainty associated with them. This will immediately disqualify analyses from submittal to SWQMIS. Therefore, data with these types of problems should not be reported to the TCEQ. Additionally, any data collected or analyzed by means other than those stated in the QAPP, or data suspect for any reason should not be submitted for loading and storage in SWQMIS.


B5 QUALITY CONTROL Sampling Quality Control Requirements and Acceptability Criteria The minimum Field QC Requirements are outlined in the TCEQ Surface Water Quality Monitoring Procedures. Specific requirements are outlined below. Field QC sample results are submitted with the laboratory data report (see Section A9.). Field blank - Field blanks are required for total metals-in-water samples when collected without sample equipment (i.e., as grab samples). A field blank is prepared in the field by filling a clean container with pure deionized water and appropriate preservative, if any, for the specific sampling activity being undertaken. Field blanks are used to assess the contamination from field sources such as airborne materials, containers, and preservatives. Field blanks will be collected on a 10% basis, except in the case of TRWD which will collect them on a 5% basis. The analysis of field blanks should yield values lower than the LOQ. When target analyte concentrations are high, blank values should be lower than 5% of the lowest value of the batch. Field equipment blank - Field equipment blanks are required for metals-in-water samples when collected using sampling equipment. A field equipment blank is a sample of analyte-free media which has been used to rinse common sampling equipment to check the effectiveness of decontamination procedures. It is collected in the same type of container as the environmental sample, preserved in the same manner and analyzed for the same parameter. Field equipment blanks will be collected at the last site of the day for each day of sampling or on a 10% basis with the exception of the City of Arlington, which will only collect a field equipment blank at one site during each quarterly sampling event, and TRWD, which will collect them on a 5% basis. The analysis of field equipment blanks should yield values lower than the LOQ, or, when target analyte concentrations are very high, blank values must be less than 5% of the lowest value of the batch, or corrective action will be implemented. Field Split - A field split is a single sample subdivided by field staff immediately following collection and submitted to the laboratory as two separately identified samples according to procedures specified in the SWQM Procedures. Split samples are preserved, handled, shipped, and analyzed identically and are used to assess variability in all of these processes. Field splits apply to conventional samples only and are collected on a 10% basis or one per batch, whichever is greater, except as noted above for the City of Arlington and TRWD. The precision of field split results is calculated by relative percent difference (RPD) using the following equation:

RPD = |(X1 - X2)/{(X1+X2)/2} * 100| A 30% RPD criteria will be used to screen field split results as a possible indicator of excessive variability in the sample handling and analytical system. If it is determined that elevated quantities of analyte (i.e., > 5 times the LOQ) were measured and analytical variability can be eliminated as a factor, then variability in field split results will primarily be used as a trigger for discussion with field staff to ensure samples are being handled in the field correctly. Some individual sample results may be


invalidated based on the examination of all extenuating information. The information derived from field splits is generally considered to be event specific and would not normally be used to determine the validity of an entire batch; however, some batches of samples may be invalidated depending on the situation. Professional judgment during data validation will be relied upon to interpret the results and take appropriate action. The qualification (i.e., invalidation) of data will be documented on the Data Summary. Deficiencies will be addressed as specified in this section under Quality Control or Acceptability Requirements Deficiencies and Corrective Actions. Laboratory Measurement Quality Control Requirements and Acceptability Criteria Batch – A batch is defined as environmental samples that are prepared and/or analyzed together with the same process and personnel, using the same lot(s) of reagents. A preparation batch is composed of one to 20 environmental samples of the same NELAC-defined matrix, meeting the above mentioned criteria and with a maximum time between the start of processing of the first and last sample in the batch to be 25 hours. An analytical batch is composed of prepared environmental samples (extract, digestates or concentrates) which are analyzed together as a group. An analytical batch can include prepared samples originating from various environmental matrices and can exceed 20 samples. Method Specific QC requirements – QC samples, other than those specified later this section, are run (e.g., sample duplicates, surrogates, internal standards, continuing calibration samples, interference check samples, positive control, negative control, and media blank) as specified in the methods. The requirements for these samples, their acceptance criteria or instructions for establishing criteria, and corrective actions are method-specific. Detailed laboratory QC requirements and corrective action procedures are contained within the individual laboratory quality manuals (QMs). The minimum requirements that all participants abide by are stated below. Limit of Quantitation (LOQ) – The laboratory will analyze a calibration standard (if applicable) at the LOQ on each day calibrations are performed. In addition, and LOQ check standard will be analyzed with each analytical batch. Calibrations including the standard at the LOQ will meet the calibration requirements of the analytical method or corrective action will be implemented. LOQ Check Standard – An LOQ check standard consists of a sample matrix (e.g., deionized water, sand, commercially available tissue) free from the analytes of interest spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes. It is used to establish intra-laboratory bias to assess the performance of the measurement system at the lower limits of analysis. The LOQ check standard is spiked into the sample matrix at a level less than or near the LOQ for each analyte for each analytical batch of CRP samples run. The LOQ check standard is carried through the complete preparation and analytical process. LOQ Check Standards are run at a rate of one per analytical batch. The percent recovery of the LOQ check standard is calculated using the following equation in which %R is percent recovery, SR is the sample result, and SA is the reference concentration for the check standard:

%R = SR/SA * 100


Measurement performance specifications are used to determine the acceptability of LOQ Check Standard analyses as specified in Table A7.1. Laboratory Control Sample (LCS) - An LCS consists of a sample matrix (e.g., deionized water, sand, commercially available tissue) free from the analytes of interest spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes. It is used to establish intra-laboratory bias to assess the performance of the measurement system. The LCS is spiked into the sample matrix at a level less than or near the mid point of the calibration for each analyte. In cases of test methods with very long lists of analytes, LCSs are prepared with all the target analytes and not just a representative number, except in cases of organic analytes with multipeak responses. The LCS is carried through the complete preparation and analytical process. LCSs are run at a rate of one per preparation batch. Results of LCSs are calculated by percent recovery (%R), which is defined as 100 times the measured concentration, divided by the true concentration of the spiked sample. The following formula is used to calculate percent recovery, where %R is percent recovery; SR is the measured result; and SA is the true result:

%R = SR/SA * 100 Measurement performance specifications are used to determine the acceptability of LCS analyses as specified in Tables A7.1 to A7.8. Laboratory Duplicates – A laboratory duplicate is prepared by taking aliquots of a sample from the same container under laboratory conditions and processed and analyzed independently. A laboratory control sample duplicate (LCSD) is prepared in the laboratory by splitting aliquots of an LCS. Both samples are carried through the entire preparation and analytical process. LCSDs are used to assess precision and are performed at a rate of one per preparation batch. For most parameters, precision is calculated by the relative percent difference (RPD) of LCS duplicate results as defined by 100 times the difference (range) of each duplicate set, divided by the average value (mean) of the set. For duplicate results, X1 and X2, the RPD is calculated from the following equation: (If other formulas apply, adjust appropriately.)

RPD = |(X1 - X2)/{(X1+X2)/2} * 100| A bacteriological duplicate is considered to be a special type of laboratory duplicate and applies when bacteriological samples are run in the field as well as in the lab. Bacteriological duplicate analyses are performed on samples from the sample bottle on a 10% basis. Results of bacteriological duplicates are evaluated by calculating the logarithm of each result and determining the range of each pair. Measurement performance specifications are used to determine the acceptability of duplicate analyses as specified in Table A7.1. The specifications for bacteriological duplicates in Table A7.1 apply to samples with concentrations > 10 org./100mL.


Laboratory equipment blank - Laboratory equipment blanks are prepared at the laboratory where collection materials for metals sampling equipment are cleaned between uses. These blanks document that the materials provided by the laboratory are free of contamination. The QC check is performed before the metals sampling equipment is sent to the field. The analysis of laboratory equipment blanks should yield values less than the LOQ. Otherwise, the equipment should not be used. Matrix spike (MS) –Matrix spikes are prepared by adding a known mass of target analyte to a specified amount of matrix sample for which an independent estimate of target analyte concentration is available. Matrix spikes are used, for example, to determine the effect of the matrix on a method’s recovery efficiency. Percent recovery of the known concentration of added analyte is used to assess accuracy of the analytical process. The spiking occurs prior to sample preparation and analysis. Spiked samples are routinely prepared and analyzed at a rate of 10% of samples processed, or one per preparation batch whichever is greater. The information from these controls is sample/matrix specific and is not used to determine the validity of the entire batch. To the extent possible, matrix spikes prepared and analyzed over the course of the project should be performed on samples from different sites. The MS is spiked at a level less than or equal to the midpoint of the calibration or analysis range for each analyte. Percent recovery (%R) is defined as 100 times the observed concentration, minus the sample concentration, divided by the true concentration of the spike. The results from matrix spikes are primarily designed to assess the validity of analytical results in a given matrix and are expressed as percent recovery (%R). The laboratory shall document the calculation for %R. The percent recovery of the matrix spike is calculated using the following equation in which %R is percent recovery, SSR is the observed spiked sample concentration, SR is the sample result, and SA is the reference concentration of the spike added:

%R = (SSR - SR)/SA * 100 Measurement performance specifications for matrix spikes are not specified in this document. Where analytical methods specify matrix spike limits, those limits are used to qualify resultant data. Otherwise, laboratory defined limits are used. If analyses fail the matrix spike limits, the resultant data are not submitted to TCEQ’s SWQMIS database. The results are compared to the acceptance criteria as published in the mandated test method. Where there are no established criteria, the laboratory shall determine the internal criteria and document the method used to establish the limits. For matrix spike results outside established criteria, corrective action shall be documented, the data reported will be coded with the appropriate data qualifying codes, and the TRA QAO will determine if the data should be submitted to TCEQ’s SWQMIS database. Method blank –A method blank is a sample of matrix similar to the batch of associated samples (when available) that is free from the analytes of interest and is processed simultaneously with and under the same conditions as the samples through all steps of the analytical procedures, and in which no target analytes or interferences are present at concentrations that impact the analytical results for sample analyses. The method blanks are performed at a rate of once per preparation batch The method blank is used to document contamination from the analytical process. The analysis of method blanks should yield values less than the LOQ. For very high-level analyses, the blank value should be less then 5% of the lowest value of the batch, or corrective action will be implemented. Samples associated with a


contaminated blank shall be evaluated as to the best corrective action for the samples (e.g. reprocessing or data qualifying codes). In all cases the corrective action must be documented. The method blank shall be analyzed at a minimum of one per preparation batch. In those instances for which no separate preparation method is used (example: volatiles in water) the batch shall be defined as environmental samples that are analyzed together with the same method and personnel, using the same lots of reagents, not to exceed the analysis of 20 environmental samples. Quality Control or Acceptability Requirements Deficiencies and Corrective Actions Sampling QC excursions are evaluated by the Lead Organization Project Manager, in consultation with the Lead Organization QAO. In that differences in sample results are used to assess the entire sampling process, including environmental variability, the arbitrary rejection of results based on pre-determined limits is not practical. Therefore, the professional judgment of the TRA Project Manager and QAO will be relied upon in evaluating results. Rejecting sample results based on wide variability is a possibility. Field blanks for trace elements and trace organics are scrutinized very closely. Field blank values exceeding the acceptability criteria may automatically invalidate the sample, especially in cases where high blank values may be indicative of contamination which may be causal in putting a value above the standard. Notations of field split excursions and blank contamination are noted in the quarterly report and the final QC Report. Equipment blanks for metals analysis are also scrutinized very closely. Laboratory measurement quality control failures are evaluated by the laboratory staff. The disposition of such failures and the nature and disposition of the problem is reported to the TRA or WBPA Laboratory QAO. The Laboratory QAO will discuss with the TRA Project Manager. If applicable, the TRA Project Manager will include this information in the CAP and submit with the Progress Report which is sent to the TCEQ CRP Project Manager. The definition of and process for handling deficiencies and corrective action are defined in Section C1.


B6 INSTRUMENT/EQUIPMENT TESTING, INSPECTION AND MAINTENANCE

All sampling equipment testing and maintenance requirements are detailed in the TCEQ Surface Water Quality Monitoring Procedures. Sampling equipment is inspected and tested upon receipt and is assured appropriate for use. Equipment records are kept on all field equipment and a supply of critical spare parts is maintained. All laboratory tools, gauges, instrument, and equipment testing and maintenance requirements are contained within laboratory QM(s).


B7 INSTRUMENT CALIBRATION AND FREQUENCY Field equipment calibration requirements are contained in the TCEQ Surface Water Quality Monitoring Procedures. Post-calibration error limits and the disposition resulting from error are adhered to. Data not meeting post-error limit requirements invalidate associated data collected subsequent to the pre-calibration and are not submitted to the TCEQ. Detailed laboratory calibrations are contained within the QM(s).


B8 INSPECTION/ACCEPTANCE OF SUPPLIES AND CONSUMABLES Supplies and consumables which affect the quality of the sampling and analysis programs are specified and approved for use by the appropriate WBPA Project Managers. Those items include, but are not limited to: sample bottles, calibration gases, reagents, hoses, materials for decontamination of sampling equipment, deionized water, and potable water. Sample containers are either new and purchased precleaned to EPA specifications, or are cleaned to appropriate specifications by the laboratory. Calibration gases are purchased having known concentrations, and the documentation is maintained on file by the WBPA Project managers. Reagents are analytical grade or better. Hoses and sampling equipment are made of impervious materials that are suited for the materials being sampled. Deionized water is used for rinsing sampling equipment between samples, is typically obtained from the laboratory, and is shown to be free of contamination through daily conductivity testing; monthly bacteria, pH, and residual Chlorine testing; and annual heavy metals testing. Refer to the laboratory QMs for all laboratory related items.


B9 NON-DIRECT MEASUREMENTS This QAPP does not include the use of routine data obtained from non-direct measurement sources. Only data collected directly under this QAPP is submitted to the SWQMIS database.


B10 DATA MANAGEMENT Data Management Protocols are addressed in the Data Management Plan which is located in Appendix E of this document. Data will be managed in accordance with the TCEQ Surface Water Quality Monitoring Data Management Reference Guide and applicable TRA information resource management policies. Global Positioning System (GPS) equipment may be used as a component of the information required by the Station Location (SLOC) request process for creating the certified positional data that will ultimately be entered into the TCEQ’s SWQMIS database. Positional data obtained by the Clean Rivers Program grantees using a Global Positioning System will follow the TCEQ’s OPP 8.11 and 8.12 policy regarding the collection and management of positional data. All positional data entered into SWQMIS will be collected by a GPS certified individual with an agency approved GPS device to ensure that the agency receives reliable and accurate positional data. Certification can be obtained in any of three ways: completing a TCEQ training class, completing a suitable training class offered by an outside vendor, or by providing documentation of sufficient GPS expertise and experience. Contractors must agree to adhere to relevant TCEQ policies when entering GPS-collected data. In lieu of entering certified GPS coordinates, positional data may be acquired with a GPS and verified with photo interpolation using a certified source, such as Google Earth or Google Maps. The verified coordinates and map interface can then be used to develop a new station location.

Corrective Action Process for Deficiencies Deficiencies are any deviation from the QAPP, SWQM Procedures Manual, SOPs, or Data Management Reference Guide. Deficiencies may invalidate resulting data and may require corrective action. Corrective action may include for samples to be discarded and re-collected. Deficiencies are documented in logbooks, field data sheets, etc. by field or laboratory staff. It is the responsibility of the TRA Project Manager, in consultation with the TRA QAO, to ensure that the actions and resolutions to the problems are documented and that records are maintained in accordance with this QAPP. In addition, these actions and resolutions will be conveyed to the CRP Project Manager both verbally and in writing in the project progress reports and by completion of a corrective action plan (CAP). Corrective Action Corrective Action Plans (CAPs) Corrective Action Plans should:

• Identify the problem, nonconformity, or undesirable situation • Identify immediate remedial actions if possible • Identify the underlying cause(s) of the problem • Identify whether the problem is likely to recur, or occur in other areas • Evaluate the need for Corrective Action • Use problem-solving techniques to verify causes, determine solution, and develop an action plan • Identify personnel responsible for action • Establish timelines and provide a schedule


• Document the corrective action To facilitate the process a flow chart has been developed (see figure C1.1: Corrective Action Process for Deficiencies). Figure C1.1 Corrective Action Process for Deficiencies


Status of Corrective Action Plans will be included with quarterly progress reports. In addition, significant conditions (i.e., situations which, if uncorrected, could have a serious effect on safety or on the validity or integrity of data) will be reported to the TCEQ immediately. The TRA Project Manager is responsible for implementing and tracking corrective actions. Records of audit findings and corrective actions are maintained by the TRA Project Manager. Audit reports and corrective action documentation will be submitted to the TCEQ with the Progress Report. If audit findings and corrective actions cannot be resolved, then the authority and responsibility for terminating work are specified in the CRP QMP and in agreements in contracts between participating organizations.


C2 REPORTS TO MANAGEMENT Reports to TRA Project Management WBPAs routinely submit water quality data and associated information such as field data sheets, chain of custody forms and data management checklists to TRA CRP staff. The frequency of submittals from the WBPAs to TRA ranges from monthly to annually based on the entity. In most cases, data transmittals include both field and laboratory quality assurance information (e.g. results of field and laboratory duplicate analyses). Copies of combination field data sheets/chain of custody forms are made upon submittal of samples to TRA CRWS laboratory, and are forwarded to TRA CRP staff with lab data reports or are given directly to TRA CRP staff. Field data sheets are not obtained from TRWD, LLP, the City of Fort Worth, or the City of Dallas, but are available upon request from those entities. TRWD submits field and lab data in Excel format along with hardcopy lab QC information. CRWS submits lab data and lab QC information in both CSV format and in hardcopy for TRA, the City of Dallas metals, the City of Grand Prairie, the City of Irving, the City of Arlington nutrients and conventionals, and LLP TKN. The City of Fort Worth sends field and lab data and lab QC data in Excel format. The Cities of Grand Prairie and Irving submit their Field Data Sheets/COC Forms in hardcopy and Excel format. The City of Dallas sends field results in Excel format. The City of Arlington submits their Field Data Sheets/COC Forms in hardcopy and Excel format and the metals results and lab QC in both Excel format and hardcopy. Reports to TCEQ Project Management All reports detailed in this section are contract deliverables and are transferred to the TCEQ in accordance with contract requirements. Progress Report - Summarizes the TRA’s activities for each task; reports monitoring status, problems, delays, and status of corrective actions; and outlines the status of each task’s deliverables. Progress reports will be prepared by the TRA Project Manager and submitted on a quarterly basis to the TCEQ CRP Project Manager according to the schedule found in Appendix A: Task 3 Workplan. Monitoring Systems Audit Report and Response - Following any audit performed by the TRA, a report of findings, recommendations and response is sent to the TCEQ in the quarterly progress report. Monitoring systems audit reports and responses will be prepared by the TRA Project Manager and QAO and submitted to the TCEQ CRP Project Manager once per contract for each WBPA. Data Review Checklist and Summary – Contains basic identifying information about the data set and comments regarding inconsistencies and errors identified during data verification and validation steps or problems with data collection efforts (e.g. Deficiencies). Data review checklists and summaries will be prepared by the TRA Data Manager and reviewed by the TRA QAO and submitted to the TCEQ CRP Project Manager on a routine basis with each batch of data quality assured. The frequency and schedule of data submittals with associated data review checklists and summaries may vary but will occur at a minimum according to the schedule found in Appendix A: Task 3 Workplan.


Reports by TCEQ Project Management Contractor Evaluation - The TRA participates in a Contractor Evaluation by the TCEQ annually for compliance with administrative and programmatic standards. Results of the evaluation are submitted to the TCEQ Financial Administration Division, Procurement and Contracts Section.


D1 DATA REVIEW, VERIFICATION, AND VALIDATION All field and laboratory will be reviewed and verified for integrity and continuity, reasonableness, and conformance to project requirements, and then validated against the project objectives and measurement performance specifications which are listed in Section A7. Only those data which are supported by appropriate quality control data and meet the measurement performance specifications defined for this project will be considered acceptable, and will be reported to the TCEQ for entry into SWQMIS. The procedures for verification and validation of data are described in Section D2, below. The TRA, WBPA, or Subcontractor Data Manager is responsible for ensuring that field data are properly reviewed, verified, and submitted in the required format to enter into the EnviroData database. Likewise, the Laboratory Managers are responsible for ensuring that laboratory data are reviewed, verified, and submitted in the required format to enter into the EnviroData database. Finally, the TRA QAO is responsible for validating that all data collected meet the data quality objectives of the project and are suitable for reporting to TCEQ. The TRA Data Manager will review all new data on a 10% basis prior to submittal to TCEQ. Data will be provided to the TRA Data Manager from the WBPAs in frequencies ranging from monthly to annually.


D2 VERIFICATION AND VALIDATION METHODS All field and laboratory data will be reviewed, verified and validated to ensure they conform to project specifications and meet the conditions of end use as described in Section A7 of this document. Data review, verification, and validation will be performed using self-assessments and peer and management review as appropriate to the project task. The data review tasks to be performed by field and laboratory staff are listed in the first two columns of Table D2.1, respectively. Potential errors are identified by examination of documentation and by manual and/or computer-assisted examination of corollary or unreasonable data. If a question arises or an error is identified, the manager of the task responsible for generating the data is contacted to resolve the issue. Issues which can be corrected are corrected and documented. If an issue cannot be corrected, the task manager consults with the higher level project management to establish the appropriate course of action, or the data associated with the issue are rejected and not reported to the TCEQ for storage in SWQMIS. Field and laboratory reviews, verifications, and validations are documented. After the field and laboratory data are reviewed, another level of review is performed once the data are combined into a data set. This review step as specified in Table D2.1 is performed by the TRA Data Manager and QAO. Data review, verification, and validation tasks to be performed on the data set include, but are not limited to, the confirmation of laboratory and field data review, evaluation of field QC results, additional evaluation of anomalies and outliers, analysis of sampling and analytical gaps, and confirmation that all parameters and sampling sites are included in the QAPP. The Data Review Checklist (See Appendix D) covers three main types of review: data format and structure, data quality review, and documentation review. The Data Review Checklist is transferred with the water quality data submitted to the TCEQ to ensure that the review process is being performed. Another element of the data validation process is consideration of any findings identified during the monitoring systems audit conducted by the TCEQ CRP Lead Quality Assurance Specialist. Any issues requiring corrective action must be addressed, and the potential impact of these issues on previously collected data will be assessed. After the data are reviewed and documented, the TRA Project Manager validates that the data meet the data quality objectives of the project and are suitable for reporting to TCEQ. If any requirements or specifications of the CRP are not met, based on any part of the data review, the responsible party should document the nonconforming activities and submit the information to the TRA Data Manager with the data. This information is communicated to the TCEQ by the TRA in the Data Summary (See Appendix D).

D3 RECONCILIATION WITH USER REQUIREMENTS Data produced in this project, and data collected by other organizations (e.g., USGS, TCEQ, etc.), will be analyzed and reconciled with project data quality requirements. Data meeting project requirements will be used by the TCEQ for the Texas Water Quality Inventory and 303(d) List in accordance with TCEQ's Guidance for Assessing Texas Surface and Finished Drinking Water Quality Data, and for TMDL development, stream standards modifications, and permit decisions as appropriate. Data which do not meet requirements will not be submitted to SWQMIS nor will be considered appropriate for any of the uses noted above.


Appendix A: Task 3 Workplan


TASK 3: WATER QUALITY MONITORING Objectives: Water quality monitoring will focus on collecting information to characterize water quality in a

variety of locations and conditions. These efforts will include a combination of:

• planning and coordinating basin-wide monitoring • routine, regularly-scheduled monitoring to collect long-term information and support

statewide assessment of water quality • systematic, regularly-scheduled short-term monitoring to screen water bodies for issues • permit support monitoring to provide information for setting permit effluent limits • special study, intensive monitoring targeted to:

o identify sources and causes o assess priority water quality issues o obtain background water quality information o provide information for setting site-specific permit effluent limits o evaluate & develop statewide, regional, and site-specific water quality standards

Task Description: Description: The focus of routine monitoring in the Trinity basin will continue to be on

working with participating agencies and gaining new participating agencies to obtain their data on a voluntary basis. TRA CRP staff will collect a limited number of samples as described below.

Monitoring Description

TRA CRP staff will monitor water quality conditions at approximately 12 stations in the Trinity basin. Samples to be collected at these stations will include flow (from USGS gages), field, conventional, bacteriological, and dissolved metals. Samples will be collected either quarterly or semiannually. All monitoring procedures and methods used by within-basin participating agencies as well as TRA CRP staff will follow the guidelines prescribed in the Trinity River Authority QAPP, the TCEQ Surface Water Quality Monitoring Procedures, Volume 1: Physical and Chemical Monitoring Methods for Water, Sediment, and Tissue (RG-415) and the TCEQ Surface Water Quality Monitoring Procedures, Volume 2: Methods for Collecting and Analyzing Biological Community and Habitat Data (RG-416). TRA provides assistance to participating agencies contributing data to the Clean Rivers Program by paying for all CRP quality assurance requirements as well as additional parameters collected at TRA’s request on behalf of the Clean Rivers Program. Quality Assurance requirements funded by the program include: analysis of duplicate samples, equipment blanks and blanks as required under SWQM guidance and as negotiated with participating agencies; nitric and sulfuric acid for field preservation of parameters as required under the SWQM guidance; filter apparatuses and membranes or filter capsules for field filtration as required under SWQM guidance (i.e. for dissolved metals). TRA also provides other sampling equipment as may be deemed beneficial to the program or as necessitated by quality assurance requirements (e.g. pumps for collection and filtration of water samples, Secchi tubes for recording turbidity measurements, etc.). Stations monitored by participating agencies are detailed in Appendix B of the Basin-Wide QAPP.

Coordinated Monitoring Meeting - The Trinity River Authority will hold an annual coordinated monitoring meeting. Qualified monitoring organizations will be invited to attend the working meeting in which monitoring needs and purposes will be discussed segment by segment and station by station. Information from participants and stakeholders will be used to select stations and parameters that will enhance overall water quality monitoring coverage, eliminate duplication of effort, and address basin priorities. The changes to the monitoring schedule will be entered into the statewide database on the Internet (http://cms.lcra.org) and communicated to meeting attendees. Changes to monitoring that occur during the course of the year will be entered into the statewide database on the Internet and communicated to meeting attendees.

Progress Report

Each Progress Report will indicate the number of sampling events and the types of monitoring


conducted in the quarter, to include all types of monitoring. Biological Reports

Biological/habitat data reported to the TCEQ under an approved QAPP, will be submitted in a pdf document using the Biological Data Reporting Packet outlined in Exhibit 3D in the CRP Guidance.

Permit Support Monitoring

A summary report of permit support flow monitoring will be submitted at the end of each sampling year. The summary report will include a map, photos, a summary of the flow monitoring data, and a summary of other water quality data collected during the flow monitoring event(s). The summary report must include copies of flow monitoring data sheets (see Exhibit 3A of the CRP Guidance). Receiving Water Assessment (RWA) Reports with color photos (see the Biological Data Reporting Packet, Exhibit 3D in the CRP Guidance, for more information) will be submitted no later than six months before the permit renewal date.

Special Studies

Status reports of each special study will describe activities during the quarter. The status reports will be submitted along with the Progress Report. To help keep the public and basin stakeholders informed, the Web site will be updated in a timely manner to include key elements of Special Studies’ Reports or Summaries (e.g., status reports, executive summary, maps, data analysis).

Trinity River Authority Clean Rivers Program

FY 2010/2011 QAPP - Appendix B Monitoring Schedule for FY 2010


Appendix B Sampling Process Design and Monitoring Schedule (plan) Sample Design Rationale FY 2010 The sample design is based on the legislative intent of the Clean Rivers Program. Under the legislation, the Basin Planning Agencies have been tasked with providing data to characterize water quality conditions in support of the 305(b) assessment, and to identify significant long-term water quality trends. Based on Steering Committee input, achievable water quality objectives and priorities and the identification of water quality issues are used to develop work plans which are in accord with available resources. As part of the Steering Committee process, the TRA coordinates closely with the TCEQ and other participants to ensure a comprehensive water monitoring strategy within the watershed. FY2010 Monitoring Schedule Changes The following changes were made to the FY2010 Monitoring Schedule as a result of the FY2010 Coordinated Monitoring Meeting and represent differences from the FY2009 Monitoring Schedule:

1) TRA Lake Livingston Project Sampling –The monitoring frequencies for conventionals, bacteria, and field for sites 10689, 13685, 16148, 10696, 10700, and 10702 was increased to 2 samples per year.

2) Tarrant Regional Water District Sampling – Diurnal sampling was added at site 10942 twice a year. The frequency of monitoring at sites 10970, 15164, and 16762 was changed from 7 samples per year to 4 samples per year. The frequency of monitoring at sites 16747 and 15170 was increased from 4 samples per year to 12 samples per year. These changes reflect the annual rotation of monitoring efforts by TRWD.

Site Selection Criteria The intent of the TRA Clean Rivers Program monitoring network is to develop and maintain a basin-wide water quality monitoring program that minimizes duplicative monitoring, facilitates the assessment process, and targets monitoring to support the permits and standards process. This data collection effort involves monitoring routine water quality, using procedures that are consistent with the TCEQ SWQM program, for the purpose of data entry into the SWQMIS database maintained by the TCEQ. To this end, some general guidelines are followed when selecting sampling sites, as basically outlined below, and discussed thoroughly in the TCEQ Surface Water Quality Monitoring Procedures, Volume 1 (RG-415). Overall consideration is given to accessibility and safety. All monitoring activities have been developed in coordination with the CRP Steering Committee and with the TCEQ. 1. Locate stream sites so that samples can be safely collected from the centroid of flow. Centroid

is defined as the midpoint of that portion of stream width which contains 50 percent of the total flow. If few sites are available for a stream segment, choose one that would best represent the water body, and not an unusual condition or contaminant source. Avoid backwater areas or eddies when selecting a stream site.

2. At a minimum for reservoirs, locate sites near the dam (reservoirs) and in the major arms.

Larger reservoirs might also include stations in the middle and upper (riverine) areas. Select sites that best represent the water body by avoiding coves and back water areas. A single


monitoring site is considered representative of 25 percent of the total reservoir acres, but not more than 5,120 acres.

3. Routine monitoring sites are selected to maximize stream coverage or basin coverage. Very

long segments may require more stations. As a rule of thumb, stream segments between 25 and 50 miles long require two stations, and longer than 50 miles require three or more depending on the existence of areas with significantly different sources of contamination or potential water quality concerns. Major hydrological features, such as the confluence of a major tributary or an instream dam, may also limit the spatial extent of an assessment based on one station.

4. Because historical water quality data can be very useful in assessing use attainment or

impairment, it may be best to use sites that are on current or past monitoring schedules. 5. All classified segments (including reservoirs) should have at least one routine monitoring site

that adequately characterizes the water body, and should be coordinated with the TCEQ or other qualified monitoring entities reporting routine data to TCEQ.

6. Routine monitoring sites may be selected to bracket sources of pollution, influence of

tributaries, changes in land uses, and hydrological modifications. 7. Sites should be accessible. When possible, stream sites should have a USGS or IBWC stream

flow gauge. If not, it should be possible to conduct flow measurement during routine visits. Monitoring Sites Monitoring Tables for fiscal year 2010 are presented on the following page. Monitoring Sites for FY 2010 The sample design for surface water quality monitoring is shown in Table B1.1 below. Individual parameters represented by each parameter group are specified in Tables A7.1 to A7.8 by monitoring type code and sampling entity. Critical vs. non-critical measurements All data taken for CRP and entered into SWQMIS are considered critical.

Appendix E: TRA CRP Data Management Plan


The Texas Clean Rivers Program

Trinity River Authority

DATA MANAGEMENT PLAN

August 14, 2009


Introduction

TRA was created in 1955 to provide a range of water-related services in the Trinity River basin. Among those duties, the Authority is to maintain a Master Plan for the conservation and use of water resources in the Trinity River basin. In 1991 the Texas Legislature enacted Senate Bill 818, the Clean Rivers Act, which requires each river authority in the state to perform water quality assessments in their respective river basins. The Trinity River Authority administers the Clean Rivers Program in the Trinity basin under contract with the Texas Commission on Environmental Quality. TRA’s objectives are to establish and maintain a comprehensive, quality assured database concerning the quality of waters in the Trinity River basin and to make such data available in a uniform, usable format as to allow highly informed decisions to be made concerning these waters. The data management plan herein detailed describes the mechanisms and procedures to be used in obtaining the above stated objectives. The Trinity River Authority Clean Rivers Program obtains data from three primary sources. These sources are within basin participating agencies (WBPA) (e.g. Tarrant Regional Water District and the City of Dallas), TRA general Office routine sampling, and special studies. Each of the WBPAs maintain their own database(s) which exist in a variety of formats and can be very large. Generally, each entity has designed and implements data collection programs on its own initiative, utilizing funds independent of the CRP. WBPAs submit or will submit data routinely. Subcontractors, in contrast, will be used to conduct special studies, which may be limited in scope and time. Water quality data obtained from the above listed sources will be submitted to the TCEQ only after programs generating data are covered under the TRA QAPP or upon approval of the TCEQ CRP Project Manager. It may at times be desirable to obtain data from sources other than those listed above. These alternate sources include:

Texas Commission on Environmental Quality U. S. Geological Survey Texas Parks and Wildlife Department U. S. Fish and Wildlife Service U. S. Army Corps of Engineers

The Clean Rivers Program has identified various additional databases which may be included in this program, especially geographic coverages for sampling sites, wastewater discharges, water rights, underground and above ground storage tanks, oil and gas wells, water supply wells, and landfills. The CRP cycle begins on September 1 of odd years, which is the start of the first fiscal year of the state biennium and is the start of each CRP contract between TCEQ and TRA. The workplan for each biennium is developed beginning the preceding spring. TRA seeks recommendations from and develops basin-wide priorities with the Trinity CRP Steering Committee. TCEQ develops state-wide priorities with the CRP stakeholders group and the Long Term Objectives Committee. Basin-wide and state-wide priorities are combined in a workplan, which is then incorporated as a scope of services in the two-year TCEQ/TRA contract. The TRA


cycle is based on its fiscal year beginning December 1. Budget preparation begins early in the year and the budget is made final in October. CRP activity must be included in the budget in categories such as personnel, subcontracts, capital, etc. Many actions involving CRP do not directly affect other authority programs and are planned simply according to CRP requirements. However, some actions involving computers are planned on an authority-wide basis and CRP must adapt to those actions. Inevitably, some things change in two years.

EnviroData, TRACRAD, CRPDatabase, Master Database, and Reference Tables are to be housed on the TRA’s network. The EnviroData and TRACRAD application designs are complicated with the description of the tables, queries, macros and functions being beyond the scope of this project. Primary data storage and quality assurance will occur in EnviroData. Three (3) ancillary Access tables (Site IDs, Metadata and StoretCodes) are located in Reference Tables. These tables are linked to all applicable databases. The Site ID table


obtained from TCEQ contains information concerning sampling site locations and TCEQ site identification numbers. The metadata table contains specific information concerning each data source (WBPA or subcontractor) and is used to keep track of general information concerning each data source including years for which data exists, tag number assignments, contact personnel names and numbers, etc. Please note that the metadata table contains information pertaining to programs that are not covered under the TRA CRP QAPP.

Formats other than that described for EnviroData, TRACRAD, and CRPDatabase will be used to accommodate special water quality data sets only, with utilization of other formats extremely limited. Submission of data in other formats to the TCEQ will occur only with approval of the TCEQ CRP Project Manager, however, no such submittals are anticipated. Data which cannot be loaded into EnviroData, TRACRAD, or CRPDatabase will be stored on write only compact disks and maintained by the TRA CRP QAO. Other copies may be maintained on CRP personal computers.


III. Data Management Plan Implementation Implementation is an on-going process. A. Data Dictionary

A data dictionary is maintained for select submissions to SWQMIS. The data dictionary is housed in the TRA QAO’s office in either hardcopy or electronic text files. The data dictionary will be sub-divided as necessary. The TRA General Office does not maintain a complete Data Dictionary on site. Historical data are maintained in Data Dictionaries at the originating WBPA. All data that are generated by CRP funded projects will be included and maintained in the CRP Data Dictionary, which will be housed at the TRA General Office. All volumes will be maintained indefinitely in either hardcopy or electronic format and when applicable, will include the following reports: map(s) of sampling sites, list of sampled dates, list of sampled locations and list of sampled parameters. The data dictionary is divided according to projects (data source) and date of submission to SWQMIS.

B. Archives and Data Retention 1. FileLogOrg

a. Upon receipt of data from data source, receipt is logged in the FileLogOrg table of TRACRAD. Data received from the following sources will be assigned the corresponding source codes.

Table B.1.a Submitting Entity and Collecting Entity Codes Collecting Entity Submitting Entity

Code Collecting Entity Code

Tarrant Regional Water District TR TD Lake Livingston Project TR LL

City of Arlington TR AR City of Dallas TR DA

Trinity River Authority TR TR City of Fort Worth TR FW

City of Grand Prairie TR GP City of Irving TR IR

1) FileLogOrg contains information concerning the source of data,

type of data, date of receipt, format, and the archive location of the original data.

2) Original data files are assigned a File Name. The File Name is used to group together similar data files and links unconverted data files with the converted data.

3) Immediately after entry into FileLogOrg, the original data are archived based on File Name and retained in the QAO’s office indefinitely.


2. FileLogCRPDatabase

a. Once data have been converted and Quality Assured, they are prepared for submittal to SWQMIS.

b. Immediately after the data have been prepared for submittal, they are logged

into FileLogCRPDatabase table of TRACRAD.

1) FileLogCRPDatabase includes information concerning the date the data was loaded, the no. of records, any comments and location of the TRAC backup location.

2) The FileLogTracking table is then changed to reflect the actions

that have been made to the parent tables (i.e. the no. of records, date and tag ranges are changed to reflect the erroneous data that remains). Comments are added to specify what must be done to the erroneous data before it can undergo QA/QC.

c. After the data are logged into FileLogCRPDatabase, they are archived in text

format.

d. A copy of the data added to the CRPDatbase is made and placed in the Data Dictionary.

C. Migration, Transfer and Conversion 1. FileLogTracking

a. Once data have been imported onto the hard-drive or network to be converted into the CRP format, they are logged into FileLogTracking table of TRACRAD.

b. FileLogTracking contains information concerning the location of the data file

on the hard-drive or network, actions taken on the data file, no. of records, date range, and in which database the converted data may be found. FileLogTracking makes it possible to track data from a parent tables to the original data file or vice versa in order to ensure that data have been faithfully transferred throughout the conversion process.


2. Conversion

a. The acquisition of databases from other parties frequently involves conversion from spreadsheets, laboratory bench sheets, field notes, hard copies of historical data or other formats.

b. Conversions are performed by TRA staff or subcontractors.

c. Data are converted from their original formats and moved into database

tables to await quality assurance and quality control. D. Quality Assurance and Quality Control (QA/QC) 1. It is the policy of most or all WBPAs to check data post entry for inconsistencies

by comparing entered data to original hard copies (lab bench sheets, etc.). This process is normally conducted on a percentage basis (see TRA QAPP for further discussion on this subject).

2. In some cases, post entry electronic data conversion to the required format will be

accomplished via the use of subcontractors. In these cases, responsibility of assuring that all conversions are accomplished faithfully will be the responsibility of the subcontractor’s project manager. In other cases, data conversion is accomplished by the Data Manager who is then responsible for assuring that the conversions were completed faithfully. This will be accomplished by checking converted data against original data on a 10% basis.

3. Once data have been entered in or converted to required format, they will be

transmitted to the TRA Data Manager. This individual will then be responsible for verifying that data are in the appropriate format and, to the extent possible, free of errors. The data will then be copied into the quality assurance application.

4. After data have been entered into the quality assurance application, they are

immediately and automatically subjected to a suite of queries which examine records for outliers, incorrect storet codes, missing data in required fields, tag numbers not present in both result and event tables and incorrect site IDs. Only records which do not have any of the above errors are flagged (by the application) as acceptable.

a. Data that have been found to contain errors will be flagged to await

correction.

5. Only the CRP Coordinator, Project Manager, Data Manager, and QAO will enter data into EnviroData, TRACRAD, and CRPDatabase. These individuals will be the only individuals outside of computer services who will have read/write privileges. All other users will have read only access, so as to avoid inadvertent


deletions or alterations to data or underlying queries and macros. 6. A Data Review Checklist and Data Summary will be completed for each set of

data that has been through QA/QC and prepared for submittal to TCEQ, and/or placement on the Internet.

7. Once the Data Review Checklist and Data Summary have been completed and

erroneous data have been flagged, the data that have undergone QA/QC will be flagged as acceptable.

8. Data that have been submitted to SWQMIS are logged into FileLogCRPDatabase

and archived.

a. Procedures for logging data into FileLogCRPDatabase and archival of final data are as described previously.

E. Backup and Disaster Recovery

1. EnviroData, TRACRAD, CRPDatabase, and Reference Tables will be backed up on CD as necessary (after addition of new data, etc.).

2. The network drive that contains parent tables, conversion databases, and original data files awaiting conversion, as well as EnviroData, CRPDatabase, TRACRAD, and Reference Tables, will be backed up weekly.
