5.0 GROUNDWATER SAMPLING AND ANALYSIS <br /> Prior to sampling the depth to water will be measured utilizing an electric sounding tape. The <br /> top of the groundwater surface in the wells and the bottom of the wells will be sampled for <br /> visual observations using a clear bailer. The groundwater samples will be collected and <br /> examined for the presence of odors and indications of petroleum product. The wells will then <br /> be purged of at least three well volumes. Parameters for pH, conductivity, and temperature will <br /> be measured after removal of each well volume. Consistency of these measured properties <br /> indicate that fresh water was being drawn from the aquifer. A groundwater sampling log will <br /> be maintained for each well. The groundwater removed during, purging will be placed into a 55- <br /> gallon DOT 17 EIH drum(s) and labeled. <br /> The groundwater wall be sampled with a Teflon point source bailer. The samples would be <br /> placed into the appropriate sample container with preservatives added and labeled The samples <br /> will be stored in an cooler with ice and shipped to the BSK State-certified Analytical <br /> Laboratories an Fresno for chemical testing. <br /> rThe chemical analyses performed on the samples will include Total Petroleum Hydrocarbons as <br /> Diesel (TPH-D) by Method DHS GC/FID and Benzene, Toluene, Xylene, Ethylbenzene (BTXE) <br /> by EPA Method 5030 and 602M <br /> 6.0 REPORTING <br /> Following completion of the field work and analytical testing, a groundwater investigation report <br /> would be submitted to Van Den Bergh Foods. The report would include boring logs and well <br /> construction details for the two installed wells, sampling logs,groundwater gradient, groundwater <br /> flow direction, and analytical test results <br /> 3 <br /> &Associates <br />
