3.0 QUALITY ASSURANCE OBJECTIVES

The purpose of this section is to define goals for the level of QA effort and data requirementsin terms of precision, accuracy, representativeness, completeness, and comparability. The

overall QA objective is to adhere to quality assurance protocols and to produce useable databy ensuring development and implementation of procedures for field sampling, chain ofcustody records, laboratory analysis, and reporting that will provide legally defensible data ofknown quality.

The specific data objectives for each investigation are summarized in Section 2.0 of the FSP.Data will be compared to the Site Screening Levels (SSLs).

As summarized from the FSP, the sampling objectives are to supplement the existing data andto identify and evaluate remedial alternatives for the site. Witco believes that sufficient dataexists to fully delineate the site contaminants at present; however, the proposed fieldinvestigation is needed to further define the "clean" areas, assist in the development of actionlevels, and evaluate the condition of the water main. Witco may propose additional fieldinvestigations to further identify the vertical and horizontal extent of contamination. Additionalfield investigations may consist of test borings.

AR305078

Section No. QAPP J'%,Page _Z_ of 27 , V


The data collected as part of this field investigation will be comparable to and compatible withthe previous data collection activities, therefore, providing a 'mechanism for meeting thespecific sampling objectives of this investigation. The data collected also serves as a basis forevaluating remedial alternatives.

Any laboratory selected to perform analysis of samples must have a demonstrated ability toaccurately perform the USEPA CLP, Series 500/600 and/or SW-846 series methods as requiredfor sample analysis. The laboratory will provide documentation of recent performanceevaluation sample analysis, QA manuals, and Standard Operating Procedures (SOPs) for thesample analysis required for the review and approval of the Witco Corporation and theUSEPA/DNREC.

• Precision - Measures the mutual agreement among individual measurements of thesame property, usually under prescribed similar conditions. Precision is expressedquantitatively as the measure of variability of a group of measurements compared totheir average value. Precision is usually expressed in terms of the standard deviations,relative standard deviations, range, and relative range, or relative percent difference(RPD). Various measures of precision exist depending upon the "prescribed similarconditions". Total measurement precision will be assessed using field duplicates. Theprecision of field measurements will be assessed through replicate measurements, andacceptable results will vary by less than 30 percent (RPD). Analytical precision willbe addressed using laboratory replicates.

• Accuracy - References to the degree of agreement of a measurement, X, with anaccepted reference or true value, T, usually expressed as the difference between thetwo values, X-T, or the difference as a percentage of the reference or true value, 100(X-T)/T, and sometimes expressed as a ratio, X/T. Accuracy is a measure of the bias ina measurement system. Sources of error that introduce bias are the sampling process,

field contamination, preservation, handling, sample matrix, sample preparation,analysis techniques, and data reduction. Accuracy will be assessed using surrogatespikes and matrix spikes and is generally expressed as percent recovery. Goals foraccuracy are those published by the USEPA for the methods being used.

AR305079

Section No.Page 8 of 27-

*•• * Revision #220 November 1995

Completeness - Measures the amount of valid data obtained from a measurementsystem compared to the amount that was expected to be obtained under normalconditions. Completeness will be assured by collecting extra sample volumes so thatif breakage occurs during shipment, sufficient sample will remain to complete analysesif it is still within the method-specified holding times. For manual sampling andanalytical methods, completeness is based upon the number of valid samples collected

over a specified period. The equation used to recalculate completeness is:

Completeness = NA(/Nptx100%WhereNA, = the number of actual valid samples over a given time period, t.

Np, = the number of possible samples over a given time period, t.The completeness goal for the sample collection and analysis activities is 100%.

Representativeness - Expresses the degree to which data accurately and preciselyrepresents the characteristics of a population, parameter variations at a sampling point,a -process condition, or an environmental condition. To assure samplerepresentativeness, all sample collection will be performed in accordance with USEPA-recommended procedures for collection as set forth in the following sections of thisQAPP. The representativeness of the data will be assessed in three areas as follows:(1) the number of locations, matrices, and samples sufficient to accurately depict siteconditions; (2) the sampling procedures that must be designed so that individualsamples accurately represent the chemistry of the matrix from which they werecollected; and (3) the appropriateness of the analytical method used to the type of

sample obtained. The goal of the sampling activities is 100% representatives.

Comparability- Expresses the confidence with which one data set can be comparedto another. In order to establish a degree of comparability such that observations andconclusions can be directly compared with all historical data, standardized methodsfor holding times, preservations, shipping, and analysis will be used and certifiedcalibration standards.

AR30508I

Section No. QAPPPage 10 of '27


The integrity of the samples will be maintained throughout the sampling process;

collection, packaging, shipment, and analysis. All samples will be preservedimmediately after collection by sealing the containers and maintaining them at a low

temperature with the utilization of ice or an ice substitute and sample shuttles. Thispreservation procedure is described in the FSP.

4.3 Field Log Books

Field log books will be maintained in accordance with the FSP. Records of samplescollected, data measurements taken, and observations of events and conditions whichcould affect data quality will be recorded in the log books. These log books areintended to provide sufficient data and observations to enable participants toreconstruct events that occurred during the data collection process, help qualify data,and refresh the memory of field personnel. The sample labeling procedure is describedin the FSP.

The original data collected in the field will be considered permanent records and willbe recorded in field notebooks, data forms, sample identification tags, chain of custodyrecords and other data forms in waterproof ink. All of these documents will beauthenticated by the signature and date of the originator.

Errors will be corrected by crossing a single line through the error and entering thecorrect information. Pages will not be removed from the log book. Corrections willbe initialed and dated by the person making the correction.

5.0 SAMPLE CUSTODY

The following custody documentation procedure will be used in conjunction with thelaboratory sample documentation procedure for all samples processed through the laboratory.Sample custody procedures are designed to provide documentation of the preparation,handling, storage, shipment, and receipt of samples.

A,R305082

Section No. QAPPPafle 11 of 27


All outgoing samples will be accompanied by a Chain-of-Custody Record (COCR). This recordwill document sample collection, transfer between personnel and sample shipment to andreceipt by the laboratory. The personnel performing the sampling will be responsible forcompleting the COCR and for the care and custody of the samples collected until they aretransferred to the laboratory or a common carrier (e.g., Federal Express).

The COCR will be used as physical evidence of sample custody. Each time the sample istransferred to another custodian, the parties relinquishing and receiving the sample will signand date the record at the time of transfer.

The original signature copy of the COCR will be signed by the individual preparing theshipment. A copy of the COCR will be retained in the project file.

5.1 Sample Identification

Each sample will be assigned a unique number that will be recorded on the followingdocuments: the daily log, the label affixed to the sample container, and the Chain-of-Custody Record/Analysis Request form.

All sampling information will be recorded in the field log book, including identificationof blind duplicate samples.

Further details of sample identification are included in the FSP.

5.2 Field Custody

The sampling team will be responsible for the care and custody of the samples untilthey are delivered to the laboratory courier. The sample containers used for shipment

will be sealed on-site by the field sampling team using strapping tape and chain-of-custody seals. Sample bottles will be kept in the shipping containers except when theyare being filled. Sample shipping and handling procedures will be in compliance withthe requirements of the CLP SOW. The CLP considers sample holding times to begin

AR305083

Section No. QAPPPage 12 of 27 £

Revision20 November 1995

at the time the sample is received by the laboratory. The laboratory will comply With

sample holding times beginning at the time of sample collection. The original Chain-Of-Custody Record/Analysis Request will be dated and signed and included along withthe sample analysis request in the shipping container. The forms will be placed in aplastic bag and taped to the underside of the cooler lid.

5.3 Chain-of-Custody Record/Analysis Request Forms

The FSP and the QAPP describe the sampling and chain-of-custody paperwork to be

completed prior to, during, and after sampling activities. Chain-of-CustodyRecord/Analysis Request forms will be completed prior to sample shipment and will

identify the samples collected, the date and time of collection, the number of bottlesfilled, the requested analyses, and the sampling team members.

Quality Control (QC) samples will be clearly identified by the Matrix Spike (MS) andMatrix Spike Duplicate (MSD) notation. Field duplicate samples will be given routine,unique sample numbers which do not indicate their duplicate nature to the laboratory.

Chemical preservatives will be noted in the remarks section on the chain-of-custodyrecord.

5.4 Sample Packaging and Shipment Procedures

All samples will be promptly chilled with ice or an ice substitute to an approximatetemperature of 4° Celsius and packaged in an insulated cooler for shipment to thelaboratory. All Chain-of-Custody Record/Analysis Request forms will be placed in aplastic bag and taped to the inside cover of the cooler. Samples will be packed in amanner to avoid breakage of jars. The outside of the cooler will be sealed withcustody seals, and clear tape will be placed over the seals, completely encircling thecooler to allow the receiver to quickly ascertain whether any tampering has takenplace during transport. The shipping containers will be relinquished daily to a

AR30508U

Section No.Page_jl3_of_2Z_


. • ilaboratory courier or common carrier (e.g., Federal Express) for immediatetransportation to the laboratory facility.

5.5 Sample Receipt Procedures

Upon accepting custody of the shipping containers, the laboratory will document thereceipt of the shipping containers by signing the Chain-Of-Custody Record/AnalysisRequest. The laboratory will Record the date and time of receipt, and assess thecondition of the shipping containers and sample bottles, and any other potentialdiscrepancies. The laboratory is also responsible for an internal sample trackingsystem. When all sample analyses and QA checks have been completed in thelaboratory, the unused portions of the samples, as well as the sample containers, willbe retained for 90 days or until otherwise directed by the Project Director. The projectand laboratory implementation of chain-of-custody controls may be audited.

Envirotech's laboratory custodian is Mr. Robert McGrady.

6.0 CALIBRATION PROCEDURES

Calibration and maintenance of all equipment used for field measurements and analysis ofsamples as well as laboratory analyses are discussed here.

6.1 Field Activities

All equipment and instruments used in the field sampling program will be maintainedand calibrated to operate within the manufacturer's specifications to ensure that therequired traceability, sensitivity and precision of the equipment/instrument ismaintained. Calibration frequency and standards will be recorded for each major pieceof equipment. Normally, manufacturers calibration instructions are followed forcalibration, calibration checks and maintenance. Procedures for control andmaintenance of measuring and test equipment include identification and control of theequipment, calibration records requirements, frequency of calibration and calibration

AR305085

Section No. QAPPPane 14 of 27


checks, corrective actio'n required when equipment is found out of calibration, andspecific calibration and calibration check instructions. Reference calibration standardswill be used which are certified traceable to the National Institute of Standards andTechnology (NIST) or other acceptable standards. These may be laboratory standardswhich are prepared using laboratory procedures. All field equipment calibration andmaintenance activities will be documented in a bound notebook that is dedicated toa single instrument.

6.2 Out of Calibration Equipment

If equipment is found to be out of calibration, an evaluation will be performed to

determine the validity of the measurements made since the last calibration. When theout of calibration equipment creates a condition in which the validity of measurementsand tests are suspect, such tests or measurements should be repeated. If data has beenaffected and cannot be repeated, such data shall be annotated. The calibration logbook or calibration/maintenance file, as appropriate for the instrument in question shallbe annotated with the results of the out of calibration evaluation.

6.3 Calibration and Maintenance Records

Air monitoring instrumentation and field equipment to be used during field activitiesincludes a Photoionization Detector (PID), an Explosimeter - Oxygen Deficiency meter(O2-LEL), dra'ger tubes (carbon disulfide and hydrogen sulfide) and an Air Samplingpump. Instruments will be used alone or in conjunction with each other to gather datafor health and safety purposes as well as sampling monitoring. All instruments andother equipment will be calibrated using the appropriate standards at least once eachday during field activities, unless the manufacturers requirement and the methodologyfollowed are less stringent. Those units on rechargeable batteries will be kept on re-charge over night and power levels tested before being brought into the field.

AR305086

Section No. QAp'pPage _15 of 27


A calibration/maintenance file will be kept on all instrument and equipment used insampling or field analysis. It will include the following information for equipmentrequiring periodic calibration and for instruments requiring daily calibration:

• Name of the equipment• Equipment identification/serial number• Manufacturer• Calibration frequency (Daily, weekly, monthly, etc.)• Calibration certifications provided by the manufacturer or other outside agency

(periodic calibrations only)• Date of last calibration and date when next calibration is due• Manufacturers operating instructions• Manufacturers calibration and maintenance instructions• Local location for purchase of spare and replacement parts (when applicable)

A calibration log book(s) will be maintained and would include the followinginformation for each instrument calibrated daily and/or during use by field personnel:

• Name of the equipment• Equipment identification/serial number• Calibration frequency (daily, weekly, monthly, etc.)• Date and time of calibration/calibration check, results of the calibration,

standards used (reference lot no., batch no.), signature/initials of the personwho performed the calibration, and any maintenance performed.

Maintenance and calibration of the field equipment will be in accordance with themanufacturer's instructions. The field equipment manuals were added as AttachmentD to the QAPP.

AH305087

Section No. QAP^Page 16 of 27 •


6.4 Laboratory Equipment

Instruments and equipment used in the analytical laboratory will be controlled by aformal calibration program. The calibration program verifies that the instrumentationis capable of producing the proper type of data requested and will attain the requiredlevel of accuracy and precision. All instruments and equipment that measure a

property or quantity are subject to calibration. Calibration will be performed internallyusing primary or secondary prepared standards, and checked externally by analyzing

audit samples.

Initial calibration steps will consist of tuning and mass standardization of the MSsystem, to be performed per the manufacturer's instructions and the laboratory SOP.The entire Gas Chromatograph/Mass Spectrometer (GC/MS) system will then becalibrated by introducing standards into the system. The resulting mass spectra will becompared against the known quantities of introduced standards. Data processing forthe GC/MS calibration will be described in the laboratory SOP. Instrument parametersand operational procedures will be adjusted as necessary to meet the calibrationacceptance criteria described herein.

The requirements for the calibration of instruments or equipment are dependent on thetype of data to be collected and the expected range of instrument performance of thespecific analytical application. The guidelines herein will be used to develop aspecific calibration program that will form part of the SOP for the analytical laboratory.

Operational calibration routinely performed as part of instrument usage, such as thedevelopment of relative response factors and standard calibration curves for gaschromatographic analytical procedures, will be performed on a periodic basis. Therepetitive analysis to analysis precision of a chromatographic system can be monitoredby using a specific test mixture, such as a primary calibration standard. Calibrationperformed at specific intervals for equipment such as the use of column performancemixtures may be necessary for more diverse sample matrices.

M305088

Section No. QAPP >Page 17 of 27


It is the responsibility of the analytical laboratory to calibrate all laboratory equipmentused for analyses as required by the USEPA or other administrative agencies and at thefrequencies mandated in the appropriate test methods. Compliance with theserequirements will be verified by QA audits as appropriate.

7.0 ANALYTICAL PROCEDURES

Samples and blanks collected during the field investigation will be analyzed using theanalytical methods from USEPA CLP SOW OLM03.0 and ILM03.0 or USEPA SW846. Thesemethods have been chosen to meet the various data quality objectives for the tasks discussedin the FSP. The CLP Methods were chosen because these contain a well defined set ofprocedures including the analytical and reporting requirments to achieve the highest level ofdata quality. Also, the USEPA informed Witco that it had no preference to the use of USEPAversus DNREC analytical methods. Methodologies are summarized in Tables 1, 2, 3, and 4.Sampling containers and preservation is summarized in Table 5. Quantitation limits aresummarized in Table 6.

The sources of reagents and standards used by Envirotech are listed below:

• Inorganic Ventures, Lakewood, NJ;• Aldrich Chemical, Milwaukee, Wl;• Fisher Scientific, Springfield, Nj;• Baxter Scientific, Edison, NJ;» Leeman Labs, Lowell, MA;• Environmental Resource Associates, Arvada, CO;• RICCA Chemical, Arlington, TX;

Hi.Section No. QAPP


Malinckrodt, Chesterfield, MO.

Screening of sample locations in the field, using portable instruments, will be performedaccording to the instrument manufacturer's instructions and/or recommendations for healthand safety purposes.

8.0 DATA REDUCTION, VALIDATION, AND REPORTING

Procedures in the QAPP describe the data reduction, validation, and reporting activities to beperformed on any sample analysis results. Original data from the field and laboratory datapackages will be entered into the project records.

8.1 Data Reduction

The data is received from the analytical laboratory on a computer disk, and summarytables are then generated by adding appropriate titles and deleting non-detectedvalues, to show only parameters with detected values. This is stored in a separatecomputer file so that the original disk is not changed.

The data reduction will consist of summarizing the raw field data into a format that willfacilitate interpretation, analysis, and evaluation. Thus, the data will be presented astables, illustrations, maps, or graphs, as deemed appropriate by the Project Director.

8.2 Data Validation

A partial validation of all laboratory analytical data will initially be performed. Thevalidation will include review of Lab Chronicles - to determine sample holding times,review of sample analysis request forms - to determine if the proper analysis wereperformed, and review of chain-of-custody records - to track sample shipments. A

second individual will then perform the full data validation according to Region Ill'sLaboratory Data Validation Functional Guidelines for Evaluating Organic Analyses andRegion Ill's Laboratory Data Validation Functional Guidelines for Evaluating Inorganic

AR305090

Section No. QAPP/2.'Page 19 of 27 %


Analyses. The reviewer will also utilize the USEPA Contract Laboratory ProgramNational Functional Guidelines for Organic Data Review and for Inorganic DataReview (1994). The reviewer will certify that the data have been validated,discrepancies have been resolved if possible, and the appropriate qualifiers have beenprovided.

8.3 Data Reporting

Laboratory deliverables will consist of a complete hard copy data package inaccordance with the CLP SOW protocols and SW846.

For the report, the analytical data, including quality control samples, will be reportedin tabular form with sample identifications, matrix, parameters, and concentrations asapplicable. These tables will include any qualifiers placed on the data as a result ofvalidation procedures and/or by the laboratory. The project QA Manager is ultimatelyresponsible for the data generated in the field investigation.

Any laboratory results which are to be summarized will be entered into a spreadsheetformat. These spreadsheets will then be incorporated into the progress reports andremedial action workplans, as necessary.

All data and reports received from subcontractors, and all data and reports generatedby the Contractor will be kept maintained in the project file. The project file will beretained by the Contractor for a minimum of three years from the final completiondate.

9.0 QUALITY CONTROL PROCEDURES

QC procedures will be followed in the field as well as in the laboratory as specified in this

QAPP. The laboratory will be responsible for performing QC samples at the frequenciesspecified in the CLP SOW protocols and other methodologies used in support of the fieldinvestigation.

AR30509I

Section No. QAPPPage 20 of'S?-*


QC samples will be used to:

Assess data quality in terms of precision and accuracy.Verify that sampling procedures such as chain of custody records, decontamination,

packaging and shipping are not introducing variables into the sampling chain whichcould render the validity of samples questionable. QC samples will be regularly

prepared in the field and laboratory so that all phases of the sampling process aremonitored.The types of QC samples which will be collected and their application are discussedbelow.

Duplicates

Duplicate samples will be collected by the sampling team and will be used as arelative measure of the precision of the sample collection process. These samples willbe collected at the same time, by the same personnel, using the same procedures, thesame equipment, and in the same types of containers as used for the original samples.Duplicates are matrix specific.

The Percent Ratio is figured for each duplicate pair as follows:

Relative Percent Difference (RPD) = XI-X2 x 100%x

Percent Ratio = X1-X2 x 100%x

Where:X, = Concentration of sample 1 of duplicateX2 = Concentration of sample 2 of duplicatex = Mean of samples 1 and 2

Calculate the standard deviation for the RPDs using the sum of the squares methodshown below:

Blanks

Blanks will be used by the sampling team to assess if contaminants are beingintroduced into the sampling event at any given point. Three kinds of blanks will beused: trip blanks, field blanks, and Equipment Rinsate Blanks.

Aqueous Trip Blanks will be prepared by the laboratory for volatile organics samplingusing ASTM Type 2 water and would be included in the shipment of sample containerswhen they are shipped to the site. The purpose of Trip Blanks is to detect anyproblems caused by sample handling or container preparation. Trip blanks will beincluded in each cooler containing samples for volatile organic analyses.

Aqueous Field Blanks will be prepared by the sampling team using ASTM Type 2 waterby transferring the ASTM Type 2 water into laboratory prepared bottles. Field Blankswill be included in the sample shuttle with the collected samples.

Aqueous Equipment Rinsate Blanks will be prepared by the sampling team using ASTMType 2 water in the same manner as actual samples. Equipment Rinsate Blanks willbe included in the sample shuttle with the collected samples. The purpose ofEquipment Rinsate Blanks and Field Blanks is to assess the origination of contaminantsin'conjunction with the Trip Blanks should contaminants be identified duringlaboratory analysis.

AR305093

Section No.


Splits

The offsite laboratory splits the samples into two parts and analyzes each separatelyusing the same methods and equipment. The purpose of split samples is similar to fieldduplicates and the results will be evaluated in the same manner.Spikes (MS/MSP)

Spikes are intended to evaluate data accuracy through verification of the laboratory'sability to recover compounds from actual samples. Spikes are prepared by thelaboratory. They are prepared by spiking field samples with known amounts of thecompounds of interest. The results are reported with the laboratory data and arecalculated as percent recovery.

Percent Recovery = (T-X)/A X 100%Where:T = Total concentration found in the spiked sampleX = Original concentration in sampleA = Actual spiked concentration added to the sample

The mean and standard deviation are figured and may be plotted on Quality ControlCharts. Limits are those provided by the USEPA for the test methods used and areincluded in Table 7. Spikes are performed at a frequency of one per twenty samples,or part thereof.

Other OC Samples

Laboratory calibration blanks and calibration standards are routinely used by thelaboratory during analysis as required by the methods being conducted. These arespecified in the analytical procedure (test method) and would be included in thecontract laboratory QA Plan submitted for approval.
