8 1.0 INTRODUCTION This Quality Assurance Project Plan (QAPP) has been prepared to accompany the Work Plans and Sampling and Analysis Plans being used in the data collection programs required in the Resource Conservation and Recovery Act (RCRA) Facility Investigation RFI program for the Surficial Media Operable Unit at Santa Susana Field Laboratory (SSFL). These data are to essential to characterize the nature and extent of chemical contamination in the surficial media at SSFL, evaluate human and ecological risk, and gather data for the subsequent step of the RCRA Corrective Action Program; a Corrective Measures Study (CMS). The RCRA Corrective Action Program is under the regulatory oversight of the California Environmental Protection Agency (Cal-EPA) Department of Toxic Substance Control (DTSC). This QAPP includes the quality assurance/quality control (QA/QC) procedures to ensure that field and laboratory data quality and project work meet the data quality objectives (DQOs) for the intended data use of the surficial media sampling program at SSFL. Additionally, the objectives of this QAPP are to ensure the project work performed is in accordance with professional standards and regulatory guidelines as specified within project work plans submitted to DTSC for the Surficial Media Program. This document has been prepared with guidance from: U.S. Environmental Protection Agency, Region IX, Guidance for Preparing Quality Assurance Project Plans for Superfund Remedial Projects, U.S. Environmental Protection Agency, EPA Region 9, Requirements for Quality Assurance Program Plan Guidance, Draft.

9 Background and Purpose This QAPP incorporates the ever-green updates which have been made to the QA Program since the publication of the SSFL Quality Assurance Project Plan Addendum in (AMEC 2000). The 2000 QAPP Addendum was approved by DTSC and is the primary sampling and analysis guidance document for the RFI. However, additional laboratory analytical requirements have been published for the RFI in various work plans and reports submitted to DTSC for review and approval. DTSC has reviewed and approved some of these documents, while others are still within the DTSC review process. The purpose of this 2008 Surficial Media QAPP is to compile all QA requirements for the surficial media sampling program into a single document for ease of use by multiple contractors supporting the field and laboratory program at the SSFL. Thus, this document serves as a reference for previously published project QA requirements and provides an update to address additional requirements due to an expanded field program (i.e., naming conventions and data management). This QAPP is intended to give comprehensive QA/QC guidance for all methods and all associated analytes utilized for the surficial media RFI, and includes laboratory requirements published in project work plans and reports. The following table provides a list of project work plans and reports prepared and submitted to DTSC that describe laboratory and QA programs for various tasks for investigation of surficial media during the RFI, and that formed the basis of this document. A brief description of purpose and content is also provided, as well as review status by DTSC. These documents are not included herein, and the reader is referred to these specific documents for any site-specific application or implementation details. This 2008 Surficial Media QAPP will be updated as additional requirements are identified or specified by DTSC. 2

15 3.0 PROJECT OBJECTIVES The purpose of the RFI is to assess the nature and extent of chemical contamination in the surficial media at SSFL, to evaluate the risks to human and ecological receptors and to gather data to support the CMS. The surficial media operable unit is composed of soil, soil vapor, sediment, surface water, near-surface groundwater, air, biota, and weathered bedrock. 3.1 Problem Definition This plan has been prepared to prescribe sampling procedures, sample custody, analytical procedures, data reduction, validation and reporting, and personnel requirements to ensure that the data are of sufficient quality and quantity to adequately characterize the chemical impacts at SSFL and enable the assessment of risk to human health and the environment. A detailed description of each of the investigational activities is described in site- and task-specific RFI Work Plans and Sampling and Analysis Plans (SAPs). Primary objectives of the RFI Work Plans and SAPs include: Provide sufficient data to support ongoing surficial media assessment activities; Provide quality representation of the medium evaluated according to accuracy, precision, and completeness for both the field and analytical laboratory programs; Produce technical products of consistent quality through the formal standardization and documentation of field and laboratory techniques and activities. 8

16 4.0 DATA QUALITY OBJECTIVES (DQO) Data Quality Objectives (DQOs) prescribe the goals that ensure the data collected during surficial media sampling tasks are of adequate quality to comply with regulatory requirements by characterizing the nature and extent of contamination in the surficial media. DQOs are qualitative and quantitative statements derived from the outputs of each step of the investigative process. The DQO process is a series of planning steps based on the scientific method that is designed to ensure that the type, quantity and quality of environmental data used in decision making are appropriate for the intended application. The seven (7) steps of the DQO process include: 1. the statement of the problem; 2. the identification of the decision; 3. the identification of the inputs to the decision; 4. the definition of the boundaries of the study; 5. the development of the decision rule; 6. the specification of the limits on decision errors; and 7. the optimization of the design for obtaining data. The decision rules for the major RFI investigation activities are provided below. In general, chemical analyses to be completed, as a part of these investigation activities, will include target analyte list (TAL) parameter analyses, as listed in Table Surficial Media Sampling The problem statement for the RFI Surficial Media Operable Unit sampling program is: Comply with regulatory requirements by characterizing the nature and extent of contamination in surficial media (soil matrix, soil vapor, sediment, surface water, near-surface groundwater, air, biota, and weathered bedrock). Five decision questions were identified during the DQO process and are used to guide data collection and evaluation for the Surficial Media Operable Unit RFI. These five questions are: 1. Has historical information on chemical use areas and chemical releases been used to identify potential source areas? 2. Have source area sampling and analysis plans been developed to characterize the nature and extent of contamination? 3. Is the nature and extent of contamination at potential source areas within RFI sites characterized sufficiently for risk assessment? 4. Have potential human health and ecological impacts been assessed? 5. Have characterization and risk assessment results been used to make site action recommendations for the corrective measures study (CMS)? 9

17 The inputs to the decision for the soil investigation are data from previous and proposed investigations and the published Standardized Risk Assessment Methodology (SRAM) Work Plan, Santa Susana Field Laboratory, Venture County California, Revision 2 (MWH, 2005). The spatial boundaries for the soil investigation are the regulated unit boundaries, administrative areas at SSFL, RFI sites and adjacent drainages, adjacent open spaces and drainages, potential source areas within RFI sites and associated drainages for soil samples, near-surface groundwater, surface water, and sediment. The decision rules for the SSFL surficial media investigation include the following rules which are pertinent to the analytical program. 1. If chemical use in a potential source area is well defined, then targeted analytical suites will be used. 2. If chemical use in potential source areas is not well defined, then broader analytical suites will be based upon potential chemical releases. The full list of decision rules for the surficial media investigation can be found in the RFI Program Report, (MWH, 2004). The limits on decision errors for the surficial media investigation include the following: Type I decision error (false rejection error): Conclusion that soils are unimpacted, when in fact they are impacted. Decision is to limit further sampling and analysis based upon this information. Consequences involve possible underestimation of site risk and under-determination of extent of contamination. Type II decision error (false acceptance error): Conclude that soils are impacted, when in fact they are un-impacted. Decision is to complete additional sampling and analysis to define the extent of impact. Consequences involve the unnecessary expenditure of additional resources to conduct additional sampling and analyses. Optimization of the design for obtaining data include additional review of historical data sources, the ability to modify plans as new information becomes available and the ability to conduct additional sampling and analysis as the new information is evaluated to reduce overall uncertainties. Task-specific DQOs have also been prepared for specific areas, phases and actions of the investigation. Task-specific DQOs can be found in the RFI Program Report, (MWH 2004). Group-specific DQOs may be included in specific work plans. The QA objective for the surficial media sampling programs is that the resulting analytical data meet the criteria for precision, accuracy, representativeness, completeness and comparability established in this QAPP. The QA objectives will be met by following the standard operating procedures (SOP) included in the site-wide work plans [Work Plan Addendum (WPA) and Work Plan Addendum Amendment (WPAA) (Ogden 1996, 2000)] and site-specific work plans and field sampling plans and implementing the procedures outlined 10

18 in this QAPP. A summary of the SOPs to be used in the performance of the Surficial Media Sampling Program are provided in Table 4-1.

19 4.2 Field Measurements Field activities outlined in the work plans include screening measurement soil volatile organic compound content, field test kits to provide screening level measurements of organic and inorganic constituents, field water quality parameters (i.e., electrical conductivity (EC), ph, dissolved oxygen (DO), oxidation and reduction potential (ORP), temperature, turbidity), well discharge rates and static groundwater elevations. Field personnel will perform validation of all data obtained from field measurements by checking calibration procedures utilized in the field. Section 5 addresses QC measures that will be implemented for data validation and inspection of field measurement and analytical data. 4.3 Laboratory Analyses Surficial media samples will be collected and submitted for off-site laboratory analysis as part of the Surficial Media RFI Program. The DQO for analytical data provided by the laboratory will be expressed in terms of precision, accuracy, representativeness, completeness and comparability criteria presented in this QAPP. These DQOs will be achieved by a comparison of EPA method acceptance criteria and laboratory QC procedures. Laboratory analyses should meet the reporting limits (RL) as presented in Table

45 4.4 Data Management A database has been developed to manage the data collected at SSFL. The database will be used to integrate all field and analytical data to allow the access and evaluation of analytical and field data by the project team. Quality assurance and quality control will be maintained through the use of electronic data deliverables (EDD), reducing the need to manually enter data and the potential for transcription errors. Access to the database is restricted to the project team using password protection and will be updated by the database administrator with new analytical data when sampling and analysis activities occur at the site. 38

46 5.0 QUALITY CONTROL PROCEDURES This QAPP establishes procedures necessary to produce technical products of consistent quality and in a manner consistent with the project s DQOs. This uniformity will be accomplished through standardization and documentation of field and laboratory techniques and activities. All field and laboratory activities will be coordinated and reviewed to ensure consistency with overall project objectives. Field and laboratory activities will be performed by trained personnel and will conform to specific procedures outlined in this QAPP and the work plans and field sampling plans of the Surficial Media RFI. 5.1 Field Measurement and Sample Collection Field equipment will be used to perform various measurements according to the work plans and field sampling plans of the Surficial Media RFI Work Plans and Field Sampling Plans. Field equipment will be calibrated and used to perform the necessary field measurements in a manner consistent with development of data that are representative of site conditions. The following discuss field equipment calibration procedures for field measurements. SOPs for field measurements and sample collection procedures are included in the Work Plans and Field Sampling Plans Calibration Procedures and Frequency Field equipment used during the Surficial Media RFI Sampling Program may include photoionization detectors (PIDs) for the measurement of volatile organic compounds in soil, field test kits for screening of organic and inorganic compounds in soil, electronic sounders for measuring depth to groundwater, flow cells for measurement of temperature, ph, EC, DO and ORP, turbidimeters, and measurement containers or flow meters for measuring well discharge volumes. All equipment used during monitoring activities will be maintained, calibrated and operated according to the manufacturer guidelines and recommendations. The following guidelines will apply to equipment calibration: Calibrate PIDs daily according to manufacturers specifications; Perform test kit calibration according to manufacturers specifications; Calibrate all equipment, including instruments to measure water levels and water quality parameters, prior to field activities; Field calibration of the ph, ORP, DO and EC meters daily according to the manufacturers instructions. If an instrument, either field or laboratory, is found upon calibration, to be out of calibration criteria, the instrument will be subject to immediate corrective action in accordance with Section 7. 39

47 Preventative Maintenance All instruments and equipment will receive routine preventative maintenance. At a minimum, all instruments will be inspected for usable condition and calibration status prior to each field use Laboratory Equipment Laboratory calibration procedures will be conducted in accordance with the approved quality assurance (QA)/quality control (QC) guidelines and laboratory policies. Calibration and maintenance will be performed in accordance with approved calibration and maintenance checks QC Procedures for Field Measurements Specific procedures to be followed during collection of field measurements are outlined below and included in the Work Plans and Field Sampling Plans Volatile Compounds in Soil Screening When utilized to select sampling points for potential volatile organic compound locations, a photoionization detector (PIDs) will be used. The PID will be calibrated daily according to manufacturers specifications. Ambient measurements will be taken to establish daily site background conditions. Replicate measurements of site samples and continuing calibration samples will be used to verify accuracy of measurements Field Test Kits Screening Field test kits may be utilized for field measurements of organic or inorganic constituents in soil. Method blanks will be prepared and analyzed according to manufacturers specifications. Method blanks will be reviewed to establish potential bias in test kit procedure measurements. Continuing calibration verifications will be performed to maintain on-going rigor of the field measurement of the constituents of concern. If significant deviation from calibration is identified, measurements should be repeated. Replicate measurements will be used to verify accuracy of the data collected. If deviations in replicate measurements exceed the manufacturers recommendations, additional measurements or fixed laboratory techniques should be utilized for compound determination Water Level Measurements Water level measurements will be obtained by utilizing an electric well sounder. Replicate measurements will be used to verify the accuracy of data collected. Data will be compared to previous measurements obtained at the well site. If an unreasonable difference between current and previous measurements (i.e., abnormal readings that cannot be accounted for by local groundwater activities, changes, or trends) is observed, then measurements will be repeated to verify accuracy. Alternate instruments will be utilized to verify the accuracy of the data if re-calibration cannot be performed Water Quality Parameters Measurements of temperature, ph, electrical conductivity, DO, ORP and turbidity will be performed during well development, aquifer testing and each water-sampling event. All equipment will be calibrated prior to a monitoring event. During the sampling event, continuing calibrations will be conducted at a frequency recommended by the manufacturers specifications. 40

48 When obtaining water quality parameters, field personnel will note unusual or unreasonable variations. If variations cannot be accounted for by changes in field conditions and/or water quality stabilization, the instrument will be re-calibrated and the measurements repeated. The measurement following re-calibration will be selected and recorded on the appropriate field record Discharge Measurements Water well discharge measurements will be obtained during well development, aquifer testing, and each water-sampling event. Calibrated containers or in-line flow meters will be used Quality Control Procedures for Sample Collection The following QC procedures have been established to ensure that all surficial media samples are collected in a manner consistent with QA objectives. QC procedures during sample collection will include the following: Sample duplicates or collocated samples will be collected for approximately 5% of the samples, by matrix and method, collected for analysis during each sampling event. Duplicates will be submitted as blind samples to the laboratory. The field personnel will assign unique sample identification to the sample and record this in the field record. The field personnel will record the location of each field duplicate. One field blank is collected each time the source of field decontamination water is changed and site samples are being collected for laboratory analysis. The field blank will consist of de-ionized or distilled water procured by the field sampling team and documented in the filed notebooks. The field blank will be placed in containers equivalent to the sample containers used for the field samples. Field blanks will be submitted as blind samples to the laboratory. The field personnel will assign unique sample identification to the sample and record this in the field record. One equipment rinsate is collected each day per type of sampling equipment being utilized on site for which site samples are being collected for laboratory analysis. An equipment rinsate may also be collected to establish the lack of contamination from disposable sampling equipment. The equipment rinsate will consist of the same source water utilized for the field blank being passed over the sampling equipment after following all decontamination procedures for that piece of equipment. Equipment rinsate samples will be submitted blind to the laboratory. The field personnel will assign unique sample identification to the samples and record this in the field record. One trip blank will be carried in the sample coolers containing field samples for volatile organic compound (VOC) analyses. Trip blanks will be supplied by the fixed laboratory. The trip blanks will be submitted and analyzed for VOC and gasoline range organic hydrocarbon (GRO) analyses only. The field personnel will assign unique sample identification to the trip blank sample and record this in the field record. Matrix spike/matrix spike duplicate pair samples will be collected for 5% of the samples collected for analysis during each sampling event, by matrix and method, and will be submitted to the laboratory for analysis. Matrix spike samples will be collected at the same time, preserved and 41

49 packaged in equivalent containers and shipped to the laboratories under the same QA/QC procedures as the parent samples. Matrix spike/matrix spike duplicate samples will be collected to evaluate laboratory precision and accuracy. Sample splits will be collected for approximately 5% of the samples collected for analysis during each sampling event, by matrix and method, and will be submitted to a third party laboratory to check the performance of the primary laboratory. Samples will be collected at the same time, preserved and packaged in equivalent containers and shipped to the laboratories under the same QA/QC procedures. Split samples will be collected to evaluate laboratory performance Sample Custody Chain-of-custody procedures will be followed to track the samples. The chain-of-custody form will document the transfer of samples from the field to the laboratory. The COC will summarize the contents of the shipment and track the dates and times of any custody transfer with signatures of all parties relinquishing and receiving the samples. From the time the sample is collected, it will be under the control of sampling personnel. Before sampling personnel relinquish the samples to the designated courier or laboratory representative, the samples will be inspected, their condition documented and the samples will then be relinquished to the designated courier or laboratory representative. Upon laboratory receipt of the samples, the laboratory will accept custody of the shipped samples and verify that the information on the sample containers match the chain-of-custody records. The sample custodian will notify the Project Manager of sample receipt and confirm the work order prior to the initiation of analyses. The laboratory will use the sample identification number and assign a unique laboratory number to each sample, and ensure that all samples are transferred to the proper analyst or stored in an appropriate and secure area. The laboratory will return completed copies of the chain-of-custody forms with the analytical results. The complete forms will indicate custody of the samples by date and signature, and the work order for each sample. Preservation, Container and Holding Time criteria for surficial media samples to be collected during the RFI Surficial Media Sampling Program are listed in Table

58 5.1.5 Sample Naming The Surficial OU RFI sample naming convention was developed to allow a consistent approach for a complex investigation with multiple investigation areas and numerous laboratories. The Sample identifier, called the Sample ID, is generally an eleven-character designator for sample identification. These identifiers are tied to a specific RFI site, a unique sample location, sampling depth and sample media. The Sample IDs are the sample names shown on RFI site maps. Each Sample ID has the following format: aabbccccdeeefff (e.g., TTSB0001S001, TTQW0002T001), where: aa bb cccc d eee fff Site Identification. Two-letter RFI site identification code (TT, CT, etc.). These site IDs are specified for each RFI site in Table 5-2. Sample Matrix Type. Each sample matrix type was assigned one or several two-letter codes. For example, soil vapor samples are identified as SV samples, soil boring samples as BS, etc. Sample matrix-specific two-letter codes for sample identifiers are provided in Table 5-3. Sample Location. Sampling location number is a three-number code that relates to the location (or coordinates) of the sample (0001, 0002, etc.). Sample Type. Primary samples are designated S, duplicate samples D, trip blanks T, other QC samples Q. Sample Number. The number of the sample (relating to the sample depth) from the specific sample location. The sample number is chronologically assigned and generally increases with depth below ground surface ( 001, 002, etc.). Optional character. This optional character is appended to the sample ID to identify split samples, SP; radiochemistry samples, RAD; or other special samples. For trench samples, when multiple samples are collected within the same trench an additional character A, B, etc, would be appended to the location name. (ex. TTTS0001AS001 or TTTS0001BS001, etc.). Where additional sample volume is collected at a sample location during the same sampling event, an additional character A is appended to the location name (ex. TTTS0001AS001), in the same manner described for trench samples. For composite samples, three naming conventions may be utilized based upon the type of composite collected. The discrete samples comprising the composite sample use the standard sample identification, sample matrix type, sample location, sample type and sample number. The horizontal composite sample uses a sample number of 070 for the surficial depth, sample number of 080 for the second depth, This convention utilizes the same sample location for the discrete and composite samples which is representative of the horizontal shape of the composite area. For vertical composites, the first sample from the boring will 51

59 use a sample number of 999 and the second composite from the same boring will use the sample number of 888. The third naming convention has an additional character A, B, etc., appended to sample location to indicate the discrete samples; such as down a trench.

65 5.1.6 Laboratory Procedures Surficial media samples collected for chemical analysis will be tested in accordance with the standard United States Environmental Protection Agency (USEPA) analytical procedures identified in the work plans and field sampling plans. Analytical laboratories performing sample analyses will assure that applicable method specific quality control measures are performed in accordance with the laboratory Standard Operating Procedures (SOP). A QA data summary will be provided within all laboratory reports. The QA data summary will include the results of laboratory blanks, matrix spike/matrix spike duplicates (MS/MSD), surrogates and laboratory control samples (LCS). The laboratory report will contain information including, but not limited to: laboratory sample identification number; corresponding field sample identification; analytical method; dates samples were collected, received, extracted, and analyzed; dilution factors; sample analysis results; method detection limits reporting limits. A full raw data package will be submitted for data validation and archival purposes. The full data package will contain all information necessary to recreate analytical result and data defensibility with the exception of analytical standard preparation documentation. Standards preparation documentation must be available upon request. The analytical laboratory must maintain a copy of the full raw data package or electronic information to recreate the deliverable for a period of not less than 5 years SSFL Site Specific Modifications to Analytical Procedures To ensure consistency of analysis and reporting procedures, site specific modifications to analytical procedures and data reporting requirements shall be maintained in the form of standard operating procedures (SOPs). The purpose of these SOPs is to provide clarifications and guidance to common methods and consistency in any modification that may be incorporated to optimize existing methods for a particular compound or class of compounds. A copy of the relevant SOPs will be provided to the analytical laboratories and can be incorporated into specific work plans and sampling and analysis plans as attachments to the supplemental QAPPs as appropriate once developed. These SOPs will include dates of origination, revision and termination of applicability. 58

66 6.0 QUALITY OBJECTIVES AND CRITERIA FOR MEASUREMENT DATA The overall quality objectives and criteria for measurement data are to develop, implement and document procedures for obtaining and evaluating data in an accurate, precise, and complete manner so that analytical data, sampling procedures, and field measurements provide information that is representative of current site conditions and comparable to similar settings. This document establishes procedures necessary to produce technical products of consistent quality. Field and laboratory activities will be performed by properly trained and qualified personnel and will conform to specific procedures outlined in this QAPP and the work plans and field sampling plans as part of the RFI Surficial Media Sampling Program. Project deliverables resulting from these activities will be reviewed for precision, accuracy, representativeness, comparability, and completeness. The definitions of these terms are as follows: Precision A measure of mutual agreement among individual measurements of the same property usually under prescribed similar conditions. The result is expressed in terms of the replicate percent difference (RPD). Accuracy The degree of agreement between a measurement and an accepted reference or true value. The result is expressed in terms of the percent recovery (%R). Representativeness Refers to a sample or group of samples that reflects the characteristics of the media at the sampling point. It also includes how well the sampling point represents the actual parameter variations that are under study. Comparability Expresses the confidence with which one data set can be compared to another. Completeness The amount of valid data obtained from a measurement system compared to the amount that is expected and necessary to meet the project data goals. Sensitivity Sensitivity is based on the analytical instrument reporting limits determined by each subcontract laboratory. The analytical reporting limits will be determined based on the completion of instrument specific method detection limit (MDL) studies performed at least annually in accordance with the methods prescribed by 40 Code of Federal Regulation (CFR) Part 136, Appendix B (USEPA, 1984). The reporting limit (RL) will generally be established by multiplying the statistically calculated MDL by a factor ranging from 3 to 5 as recommended by general accepted laboratory practices and is further supported by the lowest-level analytical standard in the initial calibration process. All laboratories will report estimated detect results, J values, between the RL and the MDL for all methods unless specified otherwise in Table 4-2. Project goals for accuracy and precision are established for the results of analyses of field and laboratory QC samples. Accuracy and precision criteria are listed in Table 6-1. These criteria are based on the standard QA/QC requirements of the referenced analytical methodology and site-specific analytical history. Laboratory-defined criteria will be utilized by the laboratory to determine whether a process is within statistical control for that laboratory at that point in time. However, the more stringent of the QC criteria will be evaluated for the data validation process. The RPD criterion for field duplicates for waters is 50% and the criterion for soils is 100%. The RPD criterion for soil gas field duplicates is 100%. 59

94 Representative data will be obtained by following proper and consistent procedures as well as application of approved laboratory specific SOPs. Sampling locations will be selected as described in the site specific work plans and field sampling plans. Comparability is a qualitative parameter expressing the confidence with which one data set can be compared to another. Comparable data will be obtained by consistently using standard analytical methods and standard sampling procedures, and by reporting all values in consistent units. Results of standard and nonstandard analyses will be compared while taking into account the potential influence of differences in methodology on sample results. Comparability of laboratory data will be achieved through the use of Performance Evaluation (PE) samples obtained from an accredited vendor, and/or Standard Reference Materials (SRM) obtained from either USEPA Cooperative Research and Development Agreement (CRADA) suppliers or the National Institute of Standards and Technology (NIST) for instrument initial and continuing calibration verification. The reported analytical data will be presented in standard units. The units will represent mass of contaminant within a known volume of environmental media. For the aqueous matrix samples to be collected this is mass of contaminant in milligrams (mg) or micrograms (µg) per volume of water sample in liters (L), for solid matrices the mass of contaminant in micrograms (ug) per kilogram (kg) of dry weight sample, for tissue in mass of contaminant in µg/kg of sample; dry weight and percent lipids to be determined by project, for soil vapor sampling on-site using sampling bulbs in mass of contaminant in ug/l of soil vapor, and for ambient air sampling in mass of contaminant in ug per cubic meter (M3). Completeness is a measure of the amount of valid (usable) data obtained from a measuring system compared to the amount expected under normal conditions. The completeness goal for all data uses is that a sufficient amount of valid data be generated so that determinations can be made related to the intended data use with a high degree of confidence. The evaluation of the data completeness will be performed at the conclusion of each sampling and analysis effort. Corrective actions such as revised sample handling procedures will be implemented if problems are noted. The completeness of the data generated will be determined by comparing the amount of valid data, based on independent validation, with the total data set. The completeness goal will be 90 % or greater for data generated during the surficial media investigations. 87

95 7.0 ASSESSMENTS AND OVERSIGHT Quality assurance oversight will be performed to ensure that the established QC procedures are followed. Activities to be conducted as part of the QA objectives include field and office audits. The audits will be conducted to ensure that the data being collected are reliable and of sufficient quality to ensure that identifying deficiencies and assessing that corrective action is implemented when necessary, and to ensure that reporting project status to project management is performed on a regular basis. 7.1 Data Reduction, Validation and Reporting These procedures specify the documentation needed and the technical criteria for data reduction, validation and reporting. The laboratory will be required to submit results that are supported by sufficient backup data and QA/QC sample analysis results to enable the reviewer to determine the validity of the data Field Measurement Data Field personnel will perform validation of data obtained from field measurements by checking calibration procedures utilized in the field. Variations in data that cannot be explained by local changes will be assigned a lower level of validity and will be used for limited purposes. Validation of data will be accomplished by checking calibration records generated in the field, and by checking sampling forms and field records for completeness. A summary of data obtained from field measurements and any use limitations will be noted on data sheets or log entries Laboratory Analytical Data Laboratory analytical data will be reviewed to determine the precision, accuracy, and completeness of the reported results. Examples of the calculations of sample precision for each analytical method and matrix include the mean and the RPD calculated for MS/MSD, inorganic matrix duplicates, and field sample duplicates. Examples of calculations indicating accuracy for each analytical method and matrix include the calculation of surrogate recovery (organic compound analyses), matrix spike and LCS (all parameters). Laboratories will be required to submit sufficient backup data and QC sample analysis results to enable the reviewer to determine the usability of the data. In the event of noncompliant results, corrective action will be initiated in accordance with procedures specified below. 7.2 Internal Quality Control (QC) Internal QC consists of examination and inspection of collected data as described in the procedures for field data collection, sample collection, and analysis. Internal QC also includes the independent review and check of calculations of field data and reports. Documentation of internal 88

96 QC actions will be provided on field logs, data reports, and correspondence, and maintained in the controlled project file. 7.3 Performance and System Audits Field activities will be monitored to evaluate the implementation of the project QA program to produce reliable sampling and field measurement data. Field audits will evaluate the execution of sample collection, sample identification, sample control, chain-of-custody, field documentation, instrument calibration, field measurement, and data acquisition procedures. System audits will evaluate data reduction and management activities, project record completeness and conformance to procedures for the issuance of all work products. Audit reports will be issued to the Project Manager. The selected project analytical laboratory(s) (PAL) will maintain current State of California Department of Health Services (CalDHS) Environmental Laboratory Approval Program (ELAP) certification for the parameters of analysis for the SSFL RFI Surficial Media Sampling Program or National Environmental Laboratory Accreditation Program (NELAP) through CalDHS. The lab must be approved under ELAP for each analytical method or approved by for each parameter of analysis under NELAP. If there is no California accreditation of an analytical parameter, accreditation through another NELAP accreditation body or by a Department of Defense (DoD) quality assurance program will be considered with approval from the CalEPA Quality Assurance Officer (QAO). Additional consideration will be given to emerging technology utilized to meet a specific site characterization or remediation need. The DHS may perform annual system audits of the PAL(s) and the laboratory audit findings will be available upon request. The Project Manager (or his designee) may perform internal-project-system audits, if inconsistencies or performance issues are noted during routine analytical data report assessment and inspection. 7.4 Specific Routine Procedures to Assess Data Chemical data will be validated according to accuracy, precision, and completeness for the analytical laboratory program. Data verification and validation will be performed in accordance with guidelines prescribed by the USEPA Contract Laboratory Program National Functional Guidelines for Organic Data Review (1999) and USEPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review (2004). As in accordance with and as discussed within the functional guidelines, data will be estimated for when QC criteria exceed established criteria. When extreme (as defined in the functional guidelines or determined by the reviewer) exceedances occur, data will be rejected. The professional judgment of qualified validation professionals will be utilized in the final evaluation of data quality. In the data validation reports and on the annotated sample results forms, data are qualified with the Reviewer Qualifiers noted in Table 7-1 and Reason Codes noted in Table 7-2 which identify the criteria for which the data were qualified. Only one valid reviewer qualification code will be presented for each target compound. Upon selection of a new laboratory or utilization of new methodology, the first sample delivery group of data will be validated at Level IV. Additionally, Level IV validation may be requested to investigate anomalous data points or when quality issues are identified during Level V review of 89

97 the data. All data will be validated at Level V. The following items are reviewed during the Level V validation process: sample management (collection techniques, sample containers, preservation, handling, transport, chain-of-custody, holding times); method blank sample results; blank spike and laboratory control sample (LCS) results; surrogate recoveries, if applicable; matrix spike/matrix duplicate (MS/MSD) recoveries and precision; laboratory duplicate precision, if applicable; serial dilution precision, if applicable; field quality assurance / quality control (QA/QC) sample results; and other QC indicators as applicable. Level IV validation included review of the following: sample management, gas chromatography/mass spectroscopy (GC/MS) instrument performance, initial and continuing calibration, method blank results, continuing calibration blank results, MS/MSD recoveries and precision, matrix spike sample results, surrogate results, laboratory and field QC sample results, internal standard performance, target compound identification, compound quantification, reported detection limits, and a definitive review of the raw data. In addition, all metals initial continuing calibration blanks will be evaluated for potential false positive or false negative influence. All perchlorate chromatograms will be evaluated for potential matrix interference and/or false positives. All tentatively identified mass spectral data will be reviewed to assign Tier I, Tier II, or Tier III TIC qualification. As described, the primary goal of the data validation program is to ensure that the data reported are representative of current site conditions. To meet this goal, a combination of statistical procedures and qualitative evaluations will be used to evaluate data quality. If noncompliant results are noted, the reported environmental data will be annotated within the database. The annotations in the database are entered into the Validator Qualifier Codes field and the Project Qualifier Codes field is updated with the final data flagging. The Validation Notes field is also annotated to reflect the qualification codes and reasons for changes in the data. This field is also used to document the original values in the event that values reported by the laboratory are changed. 90

The associated value is the quantitation limit or the estimated detection limit for dioxins. The analyte was positively identified; the associated numerical value is the approximate concentration of the analyte in the sample. The analysis indicates the presence of an analyte for which there is presumptive evidence to make a "tentative identification." The analysis indicates the presence of an analyte that has been "tentatively identified" and the associated numerical value represents its approximate concentration. The analyte was not deemed above the reported sample quantitation limit. However, the reported quantitation limit is approximate and may or may not represent the actual limit of quantitation necessary to accurately and precisely measure the analyte in the sample. The material was analyzed for, but was not detected above the level of the associated value. The associated value is either the sample quantitation limit or the sample detection limit. The associated value is the sample detection limit or the quantitation limit for perchlorate only. The associated value is an estimated quantity. Not applicable. Not applicable.

102 7.5 Corrective Actions The need for corrective action may be identified during review of data reports, during field and system audits, or during monitoring of QA activities. Identification, correction, verification, and documentation of corrective actions are controlled by this QAPP. If field and/or sample conditions are encountered that were not anticipated during project planning and the development of field procedures, the project manager will be immediately consulted concerning the appropriate direction of work. Any deviation from approved procedures will be documented in field record. Laboratory nonconformance may be noted during routine analytical data assessment and inspection. In such instances, the laboratory QA manager, and appropriate technical specialist will discuss the situation, and a corrective action will be implemented. If necessary, an audit of the laboratory will be performed to confirm that appropriate corrective actions have been implemented. 7.6 Quality Assurance Reports QA reports will be prepared identifying any audits conducted, audit findings, and finding resolution status. In addition, QA reports will summarize results of QA activities including assessments of measurement data accuracy, precision, and completeness, and any corrective action items. QA reports will be provided to the Project Manager and maintained within the project file and will be available upon request. 7.7 Data Quality Assessment Reports Data quality assessment reports will be prepared at the Program Manager s direction as part of other RFI Surficial Media Reports to summarize the overall usability of the site data or a sub-set of the data specific to the intended report. The data quality assessment report will summarize assessments of measurement data accuracy, precision, completeness, and sensitivity, and any corrective action items. The Data Quality Assessment Reports will be published as an appendix to the primary report with the data validation reports, chain of custody documents, and case narratives. 95
