PC is calculated as follows: Where: NA PC = X100 NI NA = Actual number of valid analytical results obtained, and NI = Theoretical number of results obtainable under ideal conditions. 2.2.4 Comparability Comparability expresses the confidence with which data from one sample, sampling round, site, laboratory, or project can be compared to those from another. Comparability during sampling is dependent upon sampling program design and time periods. Comparability during analysis is dependent upon analytical methods, detection limits, laboratories, units of measure, and sample preparation procedures. Comparability is determined on a qualitative rather than quantitative basis. For this project, comparability of all data collected will be ensured by adherence to standard sample collection procedures, standard fixed laboratory analytical methods, standard field measurement procedures, and standard reporting methods, including consistent units. For example, concentrations will be reported in a manner consistent with general industry practice (e.g., soil data will be reported on a dry-weight basis). In addition, to support the comparability of fixed-base laboratory analytical results with those obtained from previous or future testing, all samples will be analyzed by USEPA-approved methods, where available. The USEPA-recommended maximum permissible sample holding times (Table 2-1) for organic parameters will not be exceeded. Whenever EPA methods are not appropriate or available, recognized methods published by American Standard for Testing and Materials (ASTM) or other recognized organizations with appropriate expertise will be used. All analytical standards will be traceable to standard reference materials. Initial instrument calibrations shall be first order linear, and shall be checked at the frequency specified for the methods. 2.2.5 Representativeness Representativeness expresses the extent to which collected data define site chemical impact. Where appropriate, sample results will be statistically characterized to determine the degree to which the data accurately and precisely represent a characteristic of a population, parameter variation at a sampling point, a process, or an environmental condition. Sample collection, handling, and analytical procedures are designed to obtain the most representative sample possible. Representative samples will be achieved by the following: • Collection of samples from locations that are most likely to be representative of site conditions (based on site scoping, previous results, statistically random sample, etc.); 2-4 K:\Depts\Dept48\LAUSD\MSA WORK\QAPP\Draft Final QAPP to DTSC\QAPP for OU 1 RAP.DOC 289
• Use of appropriate sampling procedures, including proper equipment and equipment decontamination; • Use of appropriate analytical methods for the required parameters and adequate practical quantitation limits (PQLs); and • Analysis of samples within the required holding times. Sample representativeness is also affected by the portion of each sample chosen for analysis. The laboratory will adequately homogenize all samples prior to taking aliquots for analysis to ensure that the reported results are representative of the sample received. Because many homogenization techniques may cause loss of contaminants through volatilization, homogenization will not be performed for any volatile organic compound (VOC) method analyses. 2.2.6 Sensitivity The concentration of any one target compound that can be detected and/or quantified is a measure of sensitivity for that compound. Sensitivity is instrument-, compound-, method-, and matrix-specific. The definitions of terms relating to sensitivity and DQOs are presented in Section 6.2. 2.3 LABORATORY QA OBJECTIVES The selected laboratory will provide a copy of the laboratory quality assurance plan (QAP). The QAP shall define internal laboratory procedures for QA/QC and shall include descriptions of the following: • QA policies and objectives; • Organization and personnel; • Document control; • Analytical methodology standard operating procedures (SOPs); • Data generation; • Sample custody, preservation and tracking; • Data recording, reduction, review, reporting, and validation for both hard copy and electronic formats; • Security; • Documentation of client-specific requirements; • QA audits; • QC; and • Non-conformance/corrective action report (NC/CAR) procedures. The laboratory QAP must be approved by the Parsons PM prior to the initiation of analyses on this project. 2-5 K:\Depts\Dept48\LAUSD\MSA WORK\QAPP\Draft Final QAPP to DTSC\QAPP for OU 1 RAP.DOC 290
