were collected, a bentonite/grout mixture was poured into the PVC casing ■`� and screen. As the Geoprobe® boring was filled with bentonite/grout, the PVC casing and screen were removed. Each temporary well surface elevation was surveyed following installation. 3.2.3 Laboratory Analysis Soil and groundwater samples were submitted to Severn Trent Laboratories, a Califon-da-certified laboratory, and analyzed on a standard 2-week turnaround time. Soil samples were analyzed for one or more of the following constituents: • TPH in the extractable and purgeable range by United States Environmental Protection Agency (USEPA) Method 8015 Modified; ■� • Organochlorine pesticides by USEPA Method 8081A; �J . Organophosphorus pesticides by USEPA Method 8141A; . Chlorinated herbicides by USEPA Method 8151A; and • Inorganics: Ammonia as nitrogen(Method 350.1), chloride (Method 300A), nitrate as nitrogen (Method 300A), sulfate (Method 300A), and 1 pH(Method 9045C). Groundwater samples were analyzed for one or more of the following constituents (based on available groundwater): . TPH in the extractable and purgeable range using USEPA Method 8015 Modified; • Volatile organic compounds (VOCs)by USEPA Method 8260B; ■J . Chlorinated herbicides by USEPA Method 8151A; J . Total metals by USEPA method 6010B and 7470A; and IInorganics: Ammonia as nitrogen(Method 350.1), chloride (Method J 300A),nitrate as nitrogen(Method 300A),perchlorate (Method 314), ll sulfate (Method 300A), and pH (Method 150.1). 'J As part of the quality assurance/quality control procedures,the groundwater samples submitted to the laboratory for analysis were accompanied by one trip blank consisting of deionized water prepared in the laboratory, transported to the sampling location in the ice chest to be used for the transport of all samples, and transported back to the laboratory along with the other groundwater samples.
