S E C O R <br /> Groundwater Sampling Procedures <br /> The sampling procedure for the well included measuring the water level, and checking for the presence of <br /> separate-phase hydrocarbons (SPH), using either an electronic indicator and a clear Teflon® bailer or an <br /> oil-water interface probe The well was purged of approximately three casing volumes of water (or to <br /> dryness) using a centrifugal pump, gas displacement pump, or bailer The equipment and purging method <br /> used for the current sampling event were noted on the attached field data sheets During purging, <br /> temperature, pH, and electrical conductivity were monitored in order to document that these parameters <br /> were stable prior to collecting samples A groundwater sample was collected using a Teflon® bailer, <br /> placed into appropriate EPA-approved containers, labeled, logged onto a chain-of-custody document, and <br /> transported on ice to a California state-certified laboratory <br /> Laboratory Procedures <br /> Selected soil samples were analyzed for the presence of TPHg, BTEX, and MtBE by EPA Method 82608 <br /> (Single Run) Four samples collected from the drummed sod were composited at the laboratory, and <br /> analyzed for the presence of TPHg, BTEX, and MtBE by EPA Method 8260B (Single Run), and total lead <br /> by EPA Method 6010B <br /> Groundwater samples were collected by SECOR following well development, and were analyzed for the <br /> presence of TPHg, BTEX, fuel oxygenates (MtBE, TAME, DIPE, EtBE, TBA, and ethanol), 1,2-DCA, and <br /> EDB using EPA Method 82608 <br /> Soil Cuttings and Purge Water <br /> Soil cuttings generated during drilling operations were stored onsite pending characterization The sod <br /> was removed from the site by Manley, a California-certified disposal contractor, and transported to <br /> Forward in Manteca, California on January 8, 2003 <br /> AssmtRpt doc <br />
