The concentrations of <br /> these metals probably represent naturally-occurring soil conditions. Concentrations of VOCs <br /> and base neutrals and acids were below detection limits. The results of these analyses are <br /> shown on Table 2. <br /> TABLE 2 <br /> CONCENTRATIONS OF METALS AND CHEMICALS IN SOIL SAMPLES <br /> AI:CO Service Station No. 760 <br /> 225 South Cherokee Lane <br /> Lodi, California <br /> (May and June 1990) <br /> 1 <br /> Sample Total Total Total Total Base Neutral and <br /> Number Cadmium Chromium Lead Zinc VOC acids (Creoso-e) <br /> S-25--B1 0.208 4.65 3.12 20.4 #* # <br /> S-3.5-B2 0.220 5.29 4.97 21.0 # # <br /> S-15-B3 0.147 4.46 3.15 16.0 # # <br /> Results in parts per million (ppm) . <br /> < Less than the detection limit for the analytical ! <br /> methods used <br /> * Analyses performed after holding time expired <br /> # concentrations of all VOC compounds were below detection <br /> limits <br /> VOC- Volatile organic compounds <br /> Sample designation: <br /> -B1 <br /> Boxing number <br /> 1--� Depth of sample <br /> i <br /> th <br /> 9 <br /> rs <br /> AR)71100' iGeoSystemS <br />
