INTERNATIONAL TECHNOLOGY CORPORATION <br /> of water were purged prior to the collection of samples Measurements of pH, temperature, <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 "zap-loc" bags, sealed with security tape, and placed in a <br /> refrigerated ice chest Cham of custody forms accompanied the samples at all tunes <br /> (Appendix C) <br /> rr Field Analytical Services (State License No 1564) in Martinez, California analyzed the <br /> TPH as gasoline and diesel (EPA method 8015), and BTEX (EPA method 8020) samples. <br /> Coliform bacteria analyses, required by the San Joaquin County well installation special <br /> permit, were performed by FGL Environmental Analytical Chemists (State License No <br /> 48786) in Stockton, California <br /> 4.0 Summary of Findings <br /> Survey and monitoring data indicated that groundwater flows to the east-northeast with a <br /> gradient of 0 012 ft/ft (Figure 3). The water table was encountered at approximately 44 feet <br /> below 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 June sampling event Laboratory results are <br /> summarized in Table 2 Copies of the original laboratory reports are presented in Appendix <br /> D <br /> MZJ08-2742JENG/9752 MER 2 <br />
