SECTION 4 FIELD QC SAMPLES As a check on field sampling, QA/QC samples will be collected during each sampling event. Definitions for field QA/QC samples are presented below. 4.1 FIELD DUPLICATES A field duplicate is defined as a second sample collected independently at the same sampling location during the same sampling event that produced the primary sample. While such samples are not true duplicates, the results serve to indicate whether the contamination in the matrix is uniform. The laboratory will be unable to distinguish which samples are field duplicates. Each of the field duplicates will be uniquely identified with a coded identifier, which will be in the same format as other sample identifiers. Duplicate sample results are used to assess the precision of the sample collection process. Field duplicates will be collected at a minimum frequency of 1 per 20 samples (per the USEPA, Region 9 guidance). 4.2 BLANKS Equipment blanks consist of ASTM Type II water (or equivalent) poured into or pumped through the sampling device following decontamination. This blank is transferred to a sample bottle appropriate for the analysis and transported to the laboratory. The equipment blank samples shall be analyzed for the same laboratory parameters as the site samples (including VOCs, metals, hexavalent chromium, cyanide, 1,2,3- trichloropropane [TCP], 1,4-dioxane, and TPH-gasoline [TPH-g]). Equipment blanks are used to measure contamination introduced to a sample set from inadequately decontaminated sampling equipment. An equipment blank will be collected once per sampling episode. Trip blanks are used to measure potential contamination of samples by volatile organic compounds during transport. The trip blank consists of a vial filled by the laboratory with ASTM Type II water, shipped to the field, and returned to the laboratory in a cooler that contains samples for volatile organic compounds. A trip blank shall be included in every cooler containing samples for analyses for VOCs (Method SW8260B) and analyzed for VOCs. A trip blank shall be included in every cooler containing samples for analyses for TPHg (Method SW8015) and analyzed for TPH-g (SW8015). 4-1 K:\Depts\Dept48\LAUSD\MSA WORK\QAPP\Draft Final QAPP to DTSC\QAPP for OU 1 RAP.DOC 297
SECTION 5 SAMPLING PROTOCOLS Detailed soil and groundwater sampling protocols are provided in the draft Site-Wide Groundwater Monitoring Plan (GWMP) (Parsons, 2003). Soil gas sampling protocols are provided in the Remedial Investigation Workplan (Parsons, 2005). These sampling protocols will also be implemented during Supplemental Site Investigation (SSI) and the RAP. 5.1 SAMPLE CONTAINERS The laboratory will provide sample containers, labels, chain-of-custody forms, and coolers to the project site. Properly cleaned sample containers must be used so that no target compound contamination occurs from contact with the sample container. The laboratory will provide documentation attesting to the cleanliness of the containers following their cleaning procedures. A certificate of cleanliness will be provided for any commercially purchased sample containers. It is equally important to use preservative reagents that are free of target analytes or other contaminants. The laboratory will provide documentation attesting to the purity and quality of the reagents being provided. Table 2-1 lists the types of sample containers, sample volumes, methods of preservation, and holding times for each parameter. Field team members will ship or courier samples directly to the laboratory at the end of each sampling day, which will enable the laboratory to analyze the samples within the specified holding times. 5.2 SAMPLE CONTAINMENT, PRESERVATION, AND LABELS Sample containers and preservatives defined in Table 2-1 will ensure compatibility with USEPA protocols and will minimize breakage during transportation. Sample labels will be affixed to each container to identify the sample number, collector's name, date and time of collection, location of sampling point, analyses requested, and preservatives added. 5.3 FIELD SAMPLE IDENTIFICATION A sample numbering system will be used to identify each sample collected during field investigations, including all field QC samples. The numbering system will be a tracking mechanism to allow retrieval of information about a particular location and to ensure that each sample is uniquely numbered. A listing of sample numbers will be maintained by the field team leader. 5-1 K:\Depts\Dept48\LAUSD\MSA WORK\QAPP\Draft Final QAPP to DTSC\QAPP for OU 1 RAP.DOC 298
