Subsurface Environmental Investigation April 7, 1989 <br /> Former Regal Service Station, Stockton, California AGS 38078-1 <br /> are presented in Table 1. Results of analyses of soil sannples <br /> analyzed for organic lead and ethylene dibromide were each below <br /> laboratory detection limits. Based on the results of the soil <br /> samples collected from beneath the underground storage tanks, <br /> Applied GeoSystems recommended excavating the tank cavity to the <br /> vertical and horizontal limits of soil contamination, if <br /> possible. <br /> TABLE 1 <br /> CHEMICAL RESULTS OF SOIL SAMPLES <br /> COLLECTED DURING TANK REMOVAL <br /> Former Regal Service Station <br /> 6425 Pacific Avenue <br /> Stockton, California <br /> (October 21, 1988) <br /> Sample Ethyl- Total <br /> Number TPH Benzene benzene Toluene Xylenes <br /> 5-17-T1 840 4.9 55 89 250 <br /> IS-17-T2 1.2 <0.1 0.1 0.2 0.3 <br /> 5-17-T3 2,200 25 100 200 710 <br /> S-17-T4 240 4.2 10 22 66 <br /> 5-17-T5 3,600 130 120 480 820 <br /> 5-18-T6 1,500 31 48 129 840 <br /> Results in parts per million <br /> TPH = Total petroleum hydrocarbons as gasoline <br /> < = Less than the detection limit for the analytical <br /> methods used <br /> Sample designation: <br /> 5-17-T1 <br /> ��-- Sample number <br /> sample depth in feet below ground surface <br /> Soil sample <br /> 4 <br /> APP11e4F GeosiWe"s <br /> �b'd E)-20-299-0ES-393M-'9ND-4351163M T2:LT 66, 6T Ndf <br />
