This work was completed at the request of <br /> Beacon oil Company. <br /> The site is located on the southeast corner of North Main Street <br /> and Alameda Street in Mant -ca. The Site 'Vicinity Map, Plate P-1, <br /> shows the location of the station, Applied GeoSystems previously <br /> ® installed three 4-inch-diameter ground-water monitoring wells <br /> (AGS Report No. 86102-1, dated December 16, 1986) . The locations <br /> of the wells relative to the site facilities are depicted on the <br /> Generalized Site Plan, Plate P-2. Previous work, summarized in <br /> our Work Plan (AGS Report No. 86102-2, dated May 26, 1987) , <br /> suggested that soil in the area immediately adjacent to and .below <br /> K: ® the tank cavity is contaminated with hydrocarbons. In addition, <br /> ground-water in the monitoring wells contained levels of <br /> hydrocarbon constituents in excess of maximum levels for drinking <br /> water recommended by the California Department of Health Services <br /> (DHS) . <br /> Depth-to-ground-water measurements were taken in each well <br /> prior <br /> to purging and sampling.
