No. E88-029 <br />DISCUSSIONS OF FINDINGS <br />The soil profile, as interpreted from the soil borings, generally consisted of <br />a fine to medium sand or a fine sand to the bottom of the borings. For more <br />detailed information regarding subsoils encountered at the project site, please <br />refer to the logs of the soil borings included at the end of this report. <br />Groundwater was not encountered in either of the soil borings. Review of <br />published data regarding groundwater conditions in the area of the project site <br />has shown groundwater to be present at an elevation of approximately 38 feet <br />above mean sea level. According to the United States Geologic Survey 7.5 <br />minute Salida topographic quadrangle map, the elevation of the project site is <br />approximately 65 feet above mean sea level. This calculated to a depth to <br />groundwater at the project site of 27 feet below existing grade. <br />The results of the chemical analysis on samples obtained during the drilling <br />operation are listed in Table I below. <br />TABLE I <br />' Concentration of Petroleum Constituents in Soils <br />(Concentrations in parts per million) <br />Petroleum Constituent 1,000 gal. 750 gal. <br />Benzene ND ND <br />Toluene ND ND <br />iEthylbenzene ND ND <br />Total Xylene Isomers ND ND <br />' Total Volatile Hydrocarbons ND 4 <br />Total Lead ND ND <br />Ethylene Dibromide ND ND <br />' ND = Non-detected <br />I <br />' KRAZAN & ASSOCIATES, INC. <br />
