INTERNATIONAL TECHNOLOGY CORPORATION <br /> and conductivity were collected to verify that the wells had stabilized prior to sampling <br /> Purging and sampling data is contained in Appendix B <br /> After purging, each well was sampled with a new Voss Technologies disposable bailer <br /> Groundwater was transferred directly from the bailer to appropriately preserved bottles <br /> supplied by the laboratory A distilled water field blank was collected. All sample bottles <br /> were labelled then placed into "zip-loc" bags, sealed with security tape, and placed in a <br /> refrigerated ice chest. Chain of custody forms accompanied the samples at all times <br /> (Appendix C) <br /> Precision Analytical Laboratory, Inc in Richmond, California analyzed the TPH as gasoline <br /> and diesel (L[JFFT and EPA 5030), and BTEX (EPA method 602) samples Coliform bacteria <br /> analyses, required by the San Joaquin County well installation special permit, were performed <br /> by FGL Environmental Analytical Chemists (State License No. 48786) in Stockton, <br /> California. <br /> 4.0 Summary of Findings <br /> Survey and monitoring data indicated that groundwater flows to the northeast with a gradient <br /> of 0 001 ft/ft (Figure 3) The water table was encountered at approximately 44 feet below <br /> grade Table 1 contains groundwater elevation data <br /> No detectable amounts of petroleum hydrocarbons or volatile organics were measured in any <br /> of the groundwater samples collected during the September sampling event Laboratory <br /> results are summarized in Table 2.
