Environmental Site Assessment Report 3 <br /> The Southland Corporation,Southwest Corner of Grant Line Road and Joe Pombo Parkway,Tracy,California August 28, 1997 <br /> Pollutant Metals; however,these concentrations are below typical background levels for each respective <br /> analyte. Copies of laboratory analyses reports and chain-of-custody manifests are included in Appendix E. <br /> 3.3 Results of Groundwater Sample Analyses <br /> Table 1 summarizes the laboratory analytical results for groundwater samples collected from the four soil <br /> borings on August 5, 1997. Benzene, MTBE, or TPH-G were not detected in the water samples collected <br /> from the four borings. No PNA or pesticide analytes were detected in the one groundwater sample <br /> analyzed (GP-4). Concentrations of copper and zinc detected in the same sample were not above typical <br /> background concentrations. Copies of laboratory analyses reports and chain-of-custody manifests are <br /> included in Appendix E. <br /> 4.0 SUMMARY AND CONCLUSIONS <br /> On August 5, 1997, four geoprobe borings were advanced to approximately 18 to 20 feet BGS in order to <br /> verify that soil and groundwater beneath the subject site has not been impacted by petroleum <br /> hydrocarbons, metals, or pesticides. A total of 16 soil samples and 4 groundwater samples were collected <br /> from the borings and submitted for laboratory analysis. Benzene, MTBE,TPH-G, and PNA and pesticide <br /> analytes were not detected in any of the soil or groundwater samples analyzed. Metal concentrations within <br /> typical background levels were detected in the four soil samples and one groundwater sample analyzed. <br /> 0544ear.rpgSth1-) - <br /> FLUOR DANIEL GTI <br />
