k%j KLEINFELDER <br /> 1 EXECUTIVE SUMMARY <br /> ' Jordan Real Estate owns a former gasoline service station located at 298 West Grantline <br /> Road in Tracy, California. During tank removal and under the direction SJLHD staff, soil <br /> and ground water samples were taken from each excavation using techniques not based on <br /> accepted standards. The analytical results probably do not reflect actual site conditions, <br /> ' but indicated petroleum hydrocarbon compounds were present Because the analytical <br /> results indicated petroleum hydrocarbon contamination was present, SJLHD requested <br /> ' Jordan Real Estate to investigate the extent of contamination Jordan Real Estate retained <br /> Kleinfelder to assess the presence of petroleum hydrocarbons on the site <br /> ' In September 1988 Meinfelder collected a total of ten soil samples (four from the two <br /> shallow excavations and two from each of the three conngs produced during installation of <br /> ' the three monitoring wells), and a total of three water samples (one from each of the <br /> monitoring wells). Analytical results from the soil sample collected in MW-3 at 4 to 4 5 <br /> feet indicated that TPH, ethyl benzene, and xyIene were present. Contaminants were not <br /> detected in the remaining soil samples Slight concentrations of TPH, xylene, and EDB <br /> were detected in ground water at MW-3 only Coliform bacteria were detected in all three <br /> ' wells,with the concentration being highest in MW-1 <br /> A ground water flow direction was calculated from water level data and indicates that the <br /> ground water flows from south to north beneath the site at a gradient of 0 265 percent <br /> ' Therefore, MW-1 appears to be an upgradient well <br /> ' Based on the findings of this phase of work, the impact to ground water appears to be <br /> minor except for EDB which was detected at concentrations exceeding the state action <br /> ' level at MW-3. A second round of ground water sampling should be performed to confirm <br /> this. Soil contamination was only found in the area north of the small excavation <br /> Kleinfelder recommends that the extent of this contamination should be assessed <br /> 145-88-201.3 1 <br />
