• Upon arriving at the site with precleaned equipment, the sampler measured the depth to water, <br /> sounded the well and checked for the presence of free phase product The sampler proceeded to <br /> J purge the well (a calculation was done for each well following sounding measurements) of <br /> groundwater using the disposable bailer The well was then allowed to recharge <br /> Between each well volume purge, conductivity, pH, and water temperature readings were <br /> obtained and noted on the Groundwater Sampling Information Sheet (see Appendix A) Once the <br /> stabilization of the readings were noted, the sample was collected from the well Purge water <br /> was stored on-site in drums pending analytical results The well sampling Information sheet <br /> containing data on temperature, conductivity, pH, depth to water, and well volumes purged can <br /> be found in Appendix A <br /> Once the well recovers to about 80% of the initial water level measurement, a new disposable <br /> bailer was used to obtain the groundwater sample which was placed into the appropriate, <br /> laboratory prepared sample containers leaving no headspace, and Immediately placed on ice for <br /> shipment to Priority Environmental Labs in Milpitas, California (a State Certified Testing Lab) <br /> under proper chain-of-custody documentation The chain-of-custody and the Laboratory <br /> Analysis Results can be found In Appendix B <br /> LABORATORY FINDINGS <br /> Three groundwater samples were analyzed for Total Petroleum Hydrocarbons as Gasoline <br /> (TPHG) and Benzene, Toluene, Ethylbenzene and Xylene (BTEX) by EPA Methods 8015 and 8020 <br /> respectively The analytical results of the groundwater samples revealed the following (see <br /> Table 2) <br /> Table 2.
