1. INTRODUCTION

As part of the ongoing investigation and evaluation of ground water conditions in Rayville,Louisiana, the Louisiana Department of Environmental Quality (LDEQ) and/or its contractorswill collect groundwater samples from approximately 8 groundwater wells located within a one-half mile vicinity of the City of Rayville Public Water Supply Well Field. This site-specificSampling and Analysis Plan has been prepared to document the requirements for thegroundwater-sampling program to be performed in the area.

LDEQ’s Quality Management Plan (QMP) establishes LDEQ’s quality system for all work performed. It outlines the LDEQ’s quality policy and describes the overall organization andgeneral approach to quality management. The QMP also provides the strategy for assessing theeffectiveness and implementation of the overall quality system, describes the roles of andinterrelationships between the various QA/QC plans and describes how the quality of work willbe controlled.

LDEQ has established Standard Operating Procedures (SOP’s) for many of the functions itperforms. These SOP’s will be followed as they apply to the work being performed.

2.2 PROBLEM DEFINITION

On the morning of June, 29, 2009 the City of Rayville Water System received complaintsregarding odor from the city water. The complaints were reported to the Louisiana Departmentof Health and Hospitals (LDHH) and subsequently to the Louisiana Department of Environmental Quality (LDEQ). In the afternoon of the same day, LDHH and LDEQrepresentatives visited the site of the Rayville public supply well field and met with RayvillePublic Works staff. LDHH representatives collected samples from public supply wells WW-3and WW-1 and several residential taps for analysis of Volatile Organic Compounds (VOCs) andbacterial counts.

On July 1, 2009, LDEQ received a copy of the analytical results from the June 29, 2009sampling event from LDHH. The results indicated concentrations of tetrachloroethylene inWW-1 above the detection limit but below the Maximum Contaminant Level (MCL) as

established by the Safe Drinking Water Act. WW-3 exhibited concentrations of several VOCscommonly associated with gasoline above the detection limit but below the MaximumContaminant Level (MCL) as established by the Safe Drinking Water Act (SDWA). Samplescollected from residential taps also revealed concentrations of gasoline-related VOCs. Some of the VOCs detected are unregulated by the SDWA; the concentration of these compounds arebelow applicable RECAP screening standards or EPA Region 6 screening standards for allsamples.

2





On July 6, 2009, LDHH returned to the well field and resampled WW-1 and WW-3 and alsosampled WW-2. The analytical results for the sampling event indicated concentrations of tetrachloroethylene and MTBE above the detection limit but below the MCL or RECAP

screening standards in WW-1. WW-2 and WW-3 exhibited concentrations of several VOCscommonly associated with gasoline above the detection limit but below the MCL. WW-2 alsoexhibited concentrations of chloroform above the detection limit but below the MCL.

The source of the gasoline-related constituents is suspected to be a release from a regulatedformer Underground Storage Tank (UST) system located near the WW-3 well head and operatedby the City of Rayville (Rayville Physical Plant, AI No. 75877). This release was discovered in1992 and at that time investigation and corrective action was initiated. This release wasremediated and granted a No Further Action – At This Time (NFA-ATT) determination inFebruary 2006. The source of the tetrachloroethylene is yet to be determined.

Following notification of contamination in the drinking water wells, LDEQ initiated thisRayville Groundwater Investigation project. The objectives of the project are three-fold: 1) toidentify the source of groundwater contamination; 2) to determine the extent of groundwater contamination; and 3) to determine if additional human and environmental exposure is occurringas a result of the groundwater contamination.

Initial actions taken by LDEQ included obtaining and reviewing a list of registered water wellswithin a one-mile radius of the Rayville Water System public supply well field, reviewingpotential sources listed in the source water protection plan for the City of Rayville, obtaining andreviewing aerial photographs to identify land use changes and potential sources, reviewingLDEQ files and communicating with the local officials. LDEQ also reviewed informationregarding the local hydrogeology to better identify source and receptor pathways, and then

conducted a survey of local groundwater wells within the area of investigation.

This site-specific Sampling and Analysis Plan has been prepared to document the requirementsfor a groundwater-sampling program to be performed at the site. Results of the sampling will bereported to LDEQ a to verify that the extent and magnitude of the plume remains defined.

2.3 PROJECT DESCRIPTION

LDEQ personnel or contractors will collect groundwater samples from 8 groundwater wells. Itis anticipated that groundwater-sampling activities will occur between January 2009 and March2009. During the sampling event, groundwater samples will be collected from each well and

analyzed for the constituents listed in Table 1 within Section 2.4. The sampling locations arelisted in Table 2 within Section 3.1.

LDEQ personnel or contractors will collect samples which will be submitted to the LDEQ’scontract laboratory for analysis. Samples will be analyzed for total volatile organiccompounds (VOC’s) using SW-846 Method 8260B or SDWA Method 524.2 dependent uponlaboratory capabilities to achieve a practical quantitation limit below 2 ppb. Additional water

quality analyses will be performed for semi-volatile organic compounds (SVOCs), totalorganic carbon (TOC), Total Petroleum Hydrocarbons – Gasoline Range Organics (TPH-GRO) fractions, Total Petroleum Hydrocarbons – Diesel Range Organics (TPH-DRO)fractions, Total Petroleum Hydrocarbons – Oil Range Organics (TPH-ORO) fractions, and

total RCRA metals. After analysis, LDEQ will have an independent contractor perform datavalidation and prepare and submit Data Summary Tables and Data Validation Reports.

2.4 QUALITY OBJECTIVES AND CRITERIA FOR MEASUREMENT DATA

Samples will be analyzed for total volatile organic compounds using SW-846 Method 8260B or SDWA Method 524.2. Minimum detection limits (MDLs) and practical quantitation limits(PQLs) are listed in Table 1 below. In addition, field parameters will be collected duringpurging and will be logged in the field notebook. The required field parameters include:temperature, pH, conductivity, oxidation/reduction potential, turbidity and dissolved oxygen.

2.5 SPECIAL TRAINING/CERTIFICATION

As appropriate to their responsibilities, project personnel will be proficient in relevant aspects of sample collection, shipping, handling and analysis; data reporting, management and validation;and the related QC requirements and practices. Each member of the technical staff mustdemonstrate proficiency with their assigned duties.

Where required, sampling personnel will be certified in and current with the Occupational Safetyand Health Administration (OSHA) Hazardous Material Site Worker Training requirements(40-hour initial training and 8-hour annual refreshers).

2.6 DOCUMENTS AND RECORDS

Field notebooks will be used to record information obtained during groundwater samplingactivities. Documentation of sampling activities will be recorded in the field notebook. Thefollowing types of information will be recorded in the field notebook:

• Location of activity• Date and time

• Personnel performing the activity• Type of personal protective equipment (PPE) used

• Weather conditions (e.g., temperature, precipitation, wind direction, relativehumidity, etc.)

• Sample type and sample collection method• The unique sample number • Well ID from which the sample was collected• Description of the sample (e.g., color, odor, clarity)

• Identification of conditions that might affect the ability to collect a representativesample.

Chain-of-custody, which begins with sample collection and terminates upon sample disposal,will be documented throughout the life cycle of each sample using a chain-of-custody form. Achain-of-custody form will be initiated during sample collection and will remain with thesamples until receipt in the laboratory. The chain-of-custody record will include the samplenumbers, date and time of collection, sampling location, name of the person who collected thesamples, preservatives used and the analyses requested. Each sample transfer will then bedocumented on the chain-of-custody form.

The laboratory will provide an analytical report to LDEQ’s Team Leader for the samplingproject. The report will be signed by the laboratory director and include a narrative about theanalyses, original completed chain-of-custody forms and any other documentation received withthe samples. A summary of the calibration data and laboratory QC data, and raw data (e.g.,instrument printouts and manual records) will also be included. At a minimum, the report willinclude the following elements:

• Dates of sample receipt, preparation and analysis

• Condition of samples upon receipt• Sample preparation and analysis procedures• Problems encountered during sample handling, storage, preparation, or analysis, and

subsequent corrective and preventive actions• Deviations from approved SOPs• Discussion of resulting data quality.

3. DATA GENERATION AND ACQUISITION

3.1 SAMPLING DESIGN

Groundwater samples will be collected from approximately each public supply well and eachprivate well within on-half mile radius or the public supply well field. The exact dates of sampling will be determined by LDEQ and/or communicated to LDEQ contractors bytechnical direction. A list of the groundwater wells to be sampled is provided in Table 2.These well locations are depicted on a map in Appendix A.

Samples will be submitted to an LDEQ contract laboratory for analysis. Table 1 in Section 2.4presents the required analyses for each grab sample from each of the wells.

Split samples will be provided to interested parties if requested and approved by LDEQ’s legalrepresentatives.

3.2 SAMPLING METHODS

All field activities will be performed as prescribed herein or under the direction of on-siteLDEQ representatives.

3.2.1 Groundwater Sampling

Samples will be collected from the wells listed in Table 2 in Section 3.1. Prior to sampling andwhere possible, water level measurements will be performed and well volumes will be calculated

6





according to the methods described in Section 3.2.1.1. The low-flow purge and sample methodwill be used for purging and sampling the groundwater wells capable of being sampled usingthis methodology. If field parameters do not stabilize or if the well does not rechargesufficiently to allow low-flow purging and sampling, then a total of three well volumes will be

purged from each well, following the procedures described in Section 3.2.1.2. Purge water removed from wells will be containerized in 55-gallon drums and disposed as either industrial or hazardous waste, as described in Section 3.2.6 or will be treated and discharged through the Cityof Rayville’s NPDES Permit as authorized by LDEQ and EPA.

3.2.1.1 Water Level Measurements

Where possible, water level measurements will be performed at each well to be sampled prior topurging. If well heads are accessible, all wells will be sounded for depth to water from top of casing only; total well depth measurements from previous sampling events will be provided byLDEQ (Appendix B) for use in well volume calculations. An electronic sounder, accurate to thenearest 0.01 feet, will be used to measure depth to water and total depth in each well. The probewill be lowered down the casing to the top of the water column, and the graduated markings onthe probe wire or tape will be used to measure the depth to water from the surveyed point on therim of the well casing.

Water-level sounding equipment will be decontaminated before and after use in each well with aphosphate-free detergent/water mixture followed by a deionized water rinse. Water levels willbe measured in wells that are suspected to have the least contamination first. Wells with knownor suspected contamination will be measured last.

3.2.1.2 Purging Requirements

In order to obtain a representative groundwater sample, the stagnant water in each well casingalong with water immediately adjacent to the well will be purged before sample collection.Purging will be performed in accordance with EPA protocols. If the well does not support thelow-flow method, purging will be performed by the traditional method of purging several fullwell volumes.

For wells that do not support the low-flow method, a minimum of three well casing volumes of water will be purged from each well. Casing volumes will be calculated based on total welldepth, standing water level and casing diameter. One casing volume will be calculated as:

V = 0.041 d2h

Where:

V = volume of one well casing of water (in gallons, 1 ft 3 = 7.48 gallons)d = inner diameter of the well casing (in inches); andh = total depth of water in the well (in feet).

7





New Teflon tubing will be used at each well location. During the purging process, water temperature, pH, turbidity, dissolved oxygen (DO), oxygen reduction potential and specificconductance will be measured using field test meters (preferably utilizing a YSI Multiprobemeter), and the measurements will be recorded in the field logbook. Samples will be collected

after three casing volumes (or 15 minutes if the purge volume cannot be calculated) have beenremoved and water quality parameters have stabilized. Typically, the temperature should notvary by more than 3%, pH by no more than 0.1 pH units, turbidity by no more than 10% for measurements greater than 1 NTU, DO by no more than 10% and specific conductance by nomore than 3% from reading to reading. No water that has been tested with a field meter probewill be collected for chemical analysis. If these parameters have not stabilized after 4 hours of purging, then the sampling personnel will cease purging, record the event in the field logbook,and collect the samples.

Samplers should avoid purging wells to dryness by slowing the purge rate. If the well isdewatered during purging, field personnel will collect the samples as soon as the water level hasrecovered sufficiently to collect the required volumes for all anticipated analyses and record theevent in the field logbook.

Field meters will be calibrated according to manufacturer's guidelines and specifications beforeand after every day of field use or otherwise specified by the manufacturer. Field probes will bedecontaminated before and after use at each well with a phosphate-free detergent/water mixturefollowed by a deionized water rinse.

3.2.1.3 Sample Collection

Once the water quality parameters measured during purging have stabilized or three wellvolumes have been purged, groundwater samples will be collected using peristaltic pumps.

Samples will be collected following EPA protocols. To minimize the potential for cross-contamination, samples will be collected first from historically less contaminated wells whenpossible, per day.

Sample container, preservation and holding time requirements are listed in Table 3. Samplecontainers will be pre-preserved by the laboratory.

The locations sampled, observations, number and type of containers and requested analyses willbe recorded in the field notebook, chain-of-custody form and field sampling report.

Immediately following collection, samples will be placed on ice in a cooler for shipment to thelaboratory and will be handled under formal chain-of-custody from the time the samples arecollected through their final disposition.

Prior to sampling each well, the water level in the well will be measured as prescribed in Section3.2.1.1 and the well purged as prescribed in Section 3.2.1.2. Wells will be sampled within 24hours of purging.

At each sampling location, samples designated for a particular analysis will be filled sequentiallybefore bottles designated for the next analysis are filled. If a duplicate sample is to be collected,all sample bottles designated for a particular analysis for both sample designations will be filled

sequentially before bottles for another analysis are filled. Groundwater samples will be collectedfrom the tubing directly into the appropriate pre-preserved sample containers, chilled andprocessed for shipment to the laboratory. When collecting samples, care will be taken not totouch the tubing to the sample container.

Vials for analysis of VOCs will be filled to insure zero headspace. After filling VOC samplevials, each vial will be inverted and checked for air bubbles. If an air bubble appears, the vialcontents will be emptied into the container used to measure purge volumes, the vial discarded,and a new sample will be collected.

3.2.2 Field QC Samples

QC samples will be collected to ensure that sample results are representative of actual fieldconditions. One trip blank will be included in each cooler sent to the lab. One duplicate fieldsample will be collected for every 10 samples. A minimum of one field blank will be collectedfor every 20 samples. Additional field blanks may be collected if warranted by field conditions.One extra volume for Matrix Spike/Matrix Spike Duplicate (MS/MSD) will be collected for every 20 samples. For each type of equipment that is decontaminated in the field, oneequipment rinsate blank will be collected for every 20 samples. During data validation,qualified personnel will review the results of QC samples and assess the impact on the associatedproject samples.

3.2.3 Equipment Decontamination

Decontamination of sampling equipment will be performed as necessary to assure the quality of samples collected. Any equipment that comes in contact with potentially contaminated soil or water will be decontaminated or disposed. Disposable equipment intended for one time use willnot be decontaminated but will be packaged for appropriate disposal. Decontamination of non-disposable equipment will occur prior to and after each use of a piece of equipment.

9





Equipment will be decontaminated in a pre-designated area on plastic sheeting, and clean bulkyequipment will be stored on plastic sheeting in uncontaminated areas. Cleaned small equipmentwill be stored in plastic bags. Materials to be stored more than a few hours will also be covered.

3.2.4 Investigation Derived Waste (IDW) Management

IDW will be managed properly. Purge water from wells will be containerized along with useddisposable sampling equipment and PPE generated during sampling of the wells, in appropriatedisposal containers.

Each container will be labeled with site identification, sampling location, depth, matrix,constituents of concern and other pertinent data for handling. If necessary, temporary hazardouswaste generator identification (ID) numbers will be obtained and these ID numbers will beentered onto hazardous waste manifests. LDEQ personnel or contractors will coordinatetransport and disposal of waste.

Purge water from wells will be containerized along with used disposable sampling equipmentand PPE generated during sampling of the wells, after being containerized, will be managed anddisposed at a permitted facility.

3.3 SAMPLE HANDLING AND CUSTODY

This section summarizes sample identification, handling, management, documentation,document control, custody and scheduling requirements. Custody procedures will beimplemented such that accurate and complete records of sample collection, transfer of samplesbetween personnel, sample shipment and receipt by the laboratory are generated and retained.

3.3.1 Sample Identification

The LDEQ Team Leader will assign and issue a unique sample identification number for eachsample collected under his/her purview. The sample identification number will be in accordancewith LDEQ protocol. Once assigned, the sample number will be included on the sample labeland referenced on the chain-of-custody form, the field logbook and all data reports related to thesample.

A label will be affixed on each sample bottle before sample collection. Information on thesampling labels will include the sample identification number, sampler's name or initials,chemical/physical preservative used, analysis requested, date/time collected and type of sample.

3.3.2 Sample Delivery

The primary point of contact (POC) for sample delivery will be the LDEQ Team Leader. TheLDEQ Team Leader will also have primary responsibility for sample labeling and identification.

10





3.3.3 Schedule

The LDEQ Team Leader will coordinate the scheduling of sample collection with thelaboratory so as to minimize sample transport and holding time. Unless otherwise approved

by LDEQ, samples will be delivered to and received by the laboratory within 48 hours of collection. The turnaround of analytical results from receipt of samples at the laboratory tosubmittal of results will be based on a standard turnaround.

3.3.4 Sample Custody

LDEQ will ensure the integrity and security of all samples using a stringent chain-of-custodyprotocol. Chain-of-custody, which begins with sample collection and terminates upon sampledisposal, will be documented throughout the life cycle of each sample. A chain-of-custody formwill be initiated during sample collection and will remain with the samples until receipt in thelaboratory. The chain-of-custody record will include the sample numbers, date and time of collection, sampling location, name of the person who collected the samples, preservatives used,and the analyses requested. Each sample transfer will then be documented on the chain-of-custody form.

At the time that custody is transferred from to the laboratory, the laboratory's sample custodianwill perform the following activities: (1) Indicate the carrier organization on the chain-of-custody form under "Relinquished By" and (2) Sign off under “Received By” and document thedate and time of transfer. Under no circumstance should there be a break in custody.

Upon receipt of samples by the analytical laboratory, the sample custodian will sign and date the“received by” portion of the chain-of-custody form. The sample custodian will also check thetemperature of each ice chest and record this information on the chain-of-custody form and

internal traffic log. If an ice chest is found to be warmer than 6°C, the field team lead will benotified. In the laboratory, the necessary documentation will be prepared and distributed to allinvolved analysts, and the samples will be stored in appropriate refrigerators. Access to thesamples will be obtained through the sample custodian.

All samples will be handled under strict chain-of-custody protocol, and in the laboratory,samples and extracts will be tracked and accounted for at all points during processing. Theoriginal sample analysis data will be captured in a permanent form, along with the appropriatedocumentation to support its quality. A sufficient level of redundancy will exist so that allinformation can be verified from multiple sources.

3.3.5 Sample Containers and Coolers

Sample containers and coolers will be inspected before each use. Sample containers will beselected, prepared, cleaned and controlled per EPA protocols. The LDEQ Team Leader willhave the sample containers shipped from the LDEQ contract laboratory and will bring completesets of containers to the sample site prior to well purging. Extra containers will be readilyavailable to field staff as contingency for damaged or potentially contaminated containers and

11





for use with samples of opportunity. Sample containers will be kept away from fuels andsolvents.

Project requirements will also include the following:

• The laboratory will provide sample bottles and coolers within 5 calendar days of notificationby the team leader.

• Coolers will be sealed with custody seals before shipment to the sampling site. The sealsmust be affixed in such a manner that the cooler cannot be opened without breaking theseals.

• Bottles will be certified clean in writing on a per-shipment basis.

• The laboratory will supply bottles that are pre-cleaned prior to purchase.

3.3.6 Sample Disposition

The laboratory will be responsible for the proper disposal of all samples and extracts.

3.3.7 Sample Delivery

Samples will be packaged and delivered by members of the sampling team following strictchain-of-custody protocols. Samples will be shipped to the laboratory at the end of each day of sampling or on the morning following the sampling event. The LDEQ Team Leader will contactthe designated laboratory POC and provide delivery information to include the person deliveringthe samples, estimated time of arrival, the number of coolers being sent and whether or not thesesamples are the last ones for the project.

Sample coolers will contain sufficient ice to maintain required temperature preservation of samples. The chain-of-custody and analysis request forms will accompany the coolers.

3.4 ANALYTICAL METHODS

This section provides routine analytical requirements and procedures that will be implementedfor this sampling program.

3.4.1 Analytical Procedures

The analytical procedures to be used in this sampling program are listed in Table 3 withinSection 3.2.

3.4.2 Calibration Procedures

Calibration procedures are specified in each of the analytical methods. Records of standardpreparation and instrument calibration will be maintained. Records will unambiguously trace

12





the preparation of standards and their use in calibration and quantitation of sample results.Calibration standards will be traceable to standard materials. Traceability to the NationalInstitute of Standards and Technology (NIST) and EPA standards will be maintained to themaximum extent possible, but the source of calibration will be documented in all cases.

3.4.3 Standards Preparation and Traceability

Traceability of standards will be accomplished by comparing in-house standards to EPA or NIST materials, and by maintaining the required records. Whenever a standard is prepared, themanufacturer’s lot number, the starting materials, the starting amount and volume, the sourceand volume of the solvent or acid, the date of preparation and the initials of the technician willbe recorded in a permanent, bound notebook. The accuracy of the standards will be establishedby comparison to previously prepared standards and by comparison to standards preparedindependently from different starting materials.

3.4.4 Preparation of Spiked Samples

The LDEQ contract laboratory will document the method used to prepare spiked samples, andthe solutions used in sample preparation must be NIST traceable and current, to the maximumextent possible. For many target compounds, however, traceability to NIST may not bepossible, and traceability to EPA standards or other nationally recognized standards will be usedinstead.

3.5 QUALITY CONTROL

Laboratory QC samples (e.g., blanks and laboratory control samples) will be included in thepreparation batch with the field samples. An analytical batch is a number of samples (not to

exceed 20 environmental samples plus the associated laboratory QC samples) that are similar incomposition (matrix) and that are extracted or digested at the same time and with the same lot of reagents. MSs and MSDs count as environmental samples. The term analytical batch alsoextends to cover samples that do not need separate extraction or digestion (e.g., volatile analysesby purge and trap). The identity of each analytical batch will be unambiguously reported withthe analyses so that a reviewer can identify the QC samples and the associated environmentalsamples.

3.6 INSTRUMENT/EQUIPMENT TESTING, INSPECTION AND

MAINTENANCE

Field and laboratory equipment will be appropriate and approved for intended uses. Theprocurement and handling of quality-affecting equipment will be controlled to ensure initial andcontinued conformance with applicable technical requirements and acceptance criteria. Quality-affecting materials that are to be controlled include, but are not limited to, field and laboratorymeasurement and testing equipment (M&TE) and sampling equipment.

13





3.6.1 Equipment Use and Management

Equipment will be selected so as to ensure that it is of the proper type, size, tolerances andsensitivity range to support its intended use.

Equipment used in the execution of work will be appropriate and approved for its intended use,and it will be operated, handled, maintained and stored in accordance with the manufacturer’sspecifications. Sample collection and storage equipment will be cleaned, stored and handledusing the necessary precautions against cross-contamination, corrosion and damage.

3.8 INSPECTION/ACCEPTANCE OF SUPPLIES AND CONSUMABLES

Materials used in the execution of work will be appropriate and approved for intended uses. Theprocurement and handling of quality-affecting materials will be controlled to ensure initial andcontinued conformance with applicable technical requirements and acceptance criteria. Theseitems will be visually inspected before shipment to the field and again before use. Inspectionelements will include, as appropriate, a review of physical condition, expiration dates,limitations of use, size and quantity, and quality grade (e.g., reagents and solvents). Quality-affecting materials that are to be controlled include, but are not limited to, sample bottles,deionized water, calibration standards for field equipment, disposable sampling supplies anddisposable personal protective equipment (PPE). Materials that do not meet performancespecifications will be segregated and labeled to preclude use.

3.9 DATA MANAGEMENT

The LDEQ contract laboratory will provide the validated data and validation report in hard copyformat to the LDEQ Team Leader.

4. ASSESSMENT AND OVERSIGHT

Prior to implementation of field activities, internal readiness reviews will be conducted byLDEQ to verify that work prerequisites have been satisfied. The readiness review provides asystematic process for assessing, verifying and ensuring the readiness of the project team toproceed with field activities, such as groundwater sampling. The focus of the readiness review is

to ensure that technical and quality procedures have been reviewed for adequacy andappropriateness and approved for implementation; personnel are suitably qualified for the work;and the proper equipment, materials and resources are identified and available. The readinessreview specifically addresses readiness issues at the following stages of project planning andexecution: (a) during the later stages of project planning (before deployment), (b) at thebeginning stages of field work (after deployment) and (c) before resuming field work after a

16





quality-mandated stop work order is lifted or after a prolonged period of stop work due to other causes.

5. DATA VALIDATION AND USABILITY

An LDEQ contractor will validate the data as required and outlined by the LDEQ followingapplicable EPA guidelines.

5.1 DATA REVIEW, VALIDATION AND VERIFICATION

The quality of data will be assessed to establish usability for their intended purpose and to foster continuous improvement in data collection efforts by identifying major or recurring sources of error. Data quality assessment will include data review, verification of contract compliance anddetermination of data usability.

For the purposes of this plan, data review is defined as the process whereby the technical meritof data is determined by the organization that generates the data. During this process, achievedQC results are compared to method-specified criteria to determine whether the analyses wereperformed under controlled conditions. Because data review criteria are based on the analyticalmethods used to generate the data, the review process and results are independent of the intendeduse of the data. Before submitting data to the validation contractor, the LDEQ contractlaboratory will be responsible for reviewing their data, implementing corrective actions wherepossible and reporting nonconformances and the corresponding corrective actions, as applicable.Field crews will review their data and implement any necessary corrective actions beforesubmitting the data for use.

5.1.1 Data Flow and Checking

The LDEQ contract laboratory analyst performing the assay will review all results with respectto QC requirements. Compiled results will be further reviewed by at least one other qualifiedindividual at the laboratory, with respect to completeness of the data package and compliancewith all contractual and in-house QC requirements. The LDEQ Team Leader will provide afinal independent review of the completed data package with respect to contract compliance anddata usability.

5.1.2 Reporting the Results of Analyses

Data provided by the LDEQ contract laboratory may be supplied in both electronic andhardcopy media. Both reports will consist essentially of a listing specifying the client IDnumber, the internal laboratory ID number, the sample date, the data prepared and/or analyzed,the method, the matrix, the parameter(s) and the measured concentration(s), units and thedetection limit. QC sample results will be reported in similar format with cross-references tounambiguously relate QC results to their associated environmental samples.

17





5.1.3 Detection Limits, Practical Quantitation Limits, and Reporting

The MDL is the minimum concentration of a substance that can be measured and reported with99 percent confidence that the analyte concentration is greater than zero. MDLs for each

method, matrix and analyte are listed in Table 1 within Section 2.4. Results less than or equal tothe MDL will be reported as the MDL value and flagged. The Practical Quantitation Limit(PQL) denotes the lowest analyte concentration in a given matrix (groundwater) thatthe Administrative Authority believes a competent lab can be expected to achieve consistently.

5.2 VERIFICATION AND VALIDATION METHODS

The LDEQ contract laboratory will apply the appropriate data qualifiers if acceptance criteriaare not met and corrective action is either not successful or not performed. Validationcontractors will review the entire data report package, determine if the data quality objectiveshave been met, and calculate the data completeness for the project.

5.3 RECONCILIATION WITH USER REQUIREMENTS

The suitability of environmental data for their intended use(s) will be determined. Data usabilityinvolves an evaluation of the quantity, type and overall quality of generated data against theproject objectives. The usability of data that are associated with QC results outside establishedacceptance criteria is generally dependent on the degree of the exceedence, whether the potentialbias is high or low and whether the uncertainty implied by the exceedence is significant.
