• M <br /> Stantec <br /> 2010 TIDEWATER STOCKTON WORK PLAN <br /> 3.3.4 Task 4 -Analytical Laboratory Testing <br /> Groundwater samples from GWE-1 and GWE-2 will be submitted to a state certified laboratory <br /> under proper chain of custody and sample preservation procedures for analysis by the following <br /> constituents: <br /> Influent groundwater samples during TPE tests: <br /> • TPHg using EPA Method 8260B; <br /> • TPHd and TPHo using EPA Method 8015 with silica gel cleanup; <br /> • Full list volatile organic compounds including benzene, toluene, ethylbenzene, total <br /> xylenes (BTEX) and fuel oxygenates (including MtBE and TBA) using Environmental <br /> Protection Agency (EPA) Method 82606; <br /> Influent groundwater samples during GWE tests: <br /> • TPHg using EPA Method 82606; <br /> • TPHd and TPHo using EPA Method 8015 with silica gel cleanup; <br /> • Full list volatile organic compounds including BTEX and fuel oxygenates (including MtBE <br /> and TBA) using Environmental Protection Agency (EPA) Method 82606; <br /> • Total organic carbon per EPA Method 415.1; <br /> • Ammonia per EPA Methods 350.1, 350.2, and 350.3; <br /> • Nitrite and Nitrate per EPA Method 353.2 <br /> • Total Phosphate per EPA Method 365.1; <br /> • Ortho Phosphate per EPA Method 365.3; and <br /> • Total and Ferrous Iron per Standard Method 183500FED. <br /> 3.3.5 Task 5—Waste Management <br /> Soil cuttings and purge and decontamination water from drilling activities will be placed in <br /> Department of Transportation-approved 55-gallon drums and temporarily stored in an approved <br /> location away from congested areas. Influent extraction water from the TPE and GWE tests will <br /> be stored in an approximately 18,000 plus gallon tank with secondary containment pending <br /> disposal. Vapors generated during the TPE portion will be treated under an existing SJVAPCD <br /> permit and discharged to the atmosphere. <br /> Groundwater will be characterized prior to transportation for disposal at an appropriate facility; <br /> or if deemed appropriate the water will be treated using the existing treatment system and <br /> discharged under the discharge permit for the facility. <br /> A composite soil sample from soil cuttings will be analyzed for leachable lead and benzene <br /> using toxicity characteristic leaching procedure (TCLP) and EPA Method 60108 (for waste <br /> characterization purposes). The composite analytical test results will be used to characterize <br /> the soil for transportation to and disposal at an appropriate disposal facility. <br /> 3.14 <br />
