Selected samples were also analyzed for organic lead using the methods <br /> recommended in the California Leaking Underground Fuel Tank (LUPI) Manual. The <br /> 1 <br /> TPHg and BTEX analyses were performed by Applied Analytical Environmental <br />' Laboratories of Fremont, California (Hazardous Waste Testing Laboratory Certificate No. <br /> 1211). The soil samples were analyzed for organic lead at Mobile Chem Labs of Martinez, <br /> California (Hazardous Waste Testing Laboratory Certificate No. 195). The results of <br /> chemical analyses of samples collected are shown on Table 1. <br /> The laboratory results of the soil samples collected from beneath the piping showed the <br />' concentration of TPHg was below detection limits in all samples except one. This sample <br />' contained a concentration of TPHg of 3.3 ppm. <br /> 6 <br /> �--- A CWIied OOOSyst&l"S <br />
