11171cot November 11, 1986 <br /> AGS Job #8696-1 <br /> Water and soil samples collected for testing were delivered to <br /> Applied GeoSystems' laboratory, which is certified by the state <br /> of California for the types of analyses performed. Soil and <br /> water samples were analyzed for total hydrocarbons and gasoline <br /> constituents (benzene, ethylbenzene, toluene, and xylenes - <br /> BETX) . Sail analyses were facilitated through solvent <br /> extraction. Water and soil analyses utilized gas chromatographic/ <br /> separation with flame- and photo-ionization detection. <br /> TABLE 1 l° 4A0 <br /> RESULTS OF CHEMICAL ANALYSES <br /> CRYSTAL CREAM AND BUTTER COMPANY <br /> 404 WEST FREMONT STREET, STOCKTON, CALIFORNIA <br /> SAMPLE TOTAL ETHYL_ <br /> NUMBER HYDROCARBONS BENZENE BENZENE TOLUENE XYLENES <br /> SOIL SAMPLES FROM BORINGS (Detection 1lmits 0.2 ppm) <br /> S-15-B1 0.2 ND ND ND ND <br /> S-15-B2 28.6 1.4 0.5 2.6 6.8 <br /> SOIL SAMPLES FROM EXCAVATION (Detection limits: S1 = 2 ppm, <br /> S2 = 0.2 ppm) <br /> Si 2,241 65 81 276 532 <br /> S2 2.1 ND ND 0.2 0.3 <br /> SOIL SAMPLES FROM SOIL PILES (Detection limits 0.2 ppm) <br /> S3 1.6 ND ND ND ND <br /> S4 43.3 ND ND ND 1.6 <br /> S5 2.2 ND ND ND ND <br /> S6 ND ND ND ND ND <br /> WATER SAMPLE FROM MW-1 (Detection limits 0.001 ppm) <br /> W-25-MW1 11.580 1.539 0.169 1.106 1.313 <br /> v-ilues in milligrams per kilogram (Parts per million- ppm) <br /> ND indicates not present or below method detection limits <br />
