f stored on the property. Prior to 1945, the area wasart o <br /> la f a in:u•sh. The site was filled about <br /> 1945 and used as U.S. Navel housing until 1965. The housing was abandoned until 1979, at <br /> which time it was demolished. The site was redeveloped in 1980 and the Swett & Crawford <br /> commercial building at 711 North Pershing was constructed. Elie site is well lanilscapecl aiid <br /> verdant. <br /> The topography in the area is flat. The area is primarily zoned for residential use, although <br /> commercial facilities are present along Pershing Avenue. <br /> a <br /> 3.0 SOIL ASSESSMENT <br /> Upgradient drilled a total of six shallow borings on the three properties. Three borings were drilled <br /> on the Caltrans property south of the Pershing Avenue on-ramp to fiiterstate 5, one boring was <br /> drilled on the Red Cross property to the north and two borings were drilled on the subject property <br /> near the location were the highest contamination was discovered by RESNA (Figure 2). <br /> The borings were drilled to depths of 3 to 5 feet below grade using a hydraulic gasoline-powered <br /> post-hole digger equipped with 6" auger bits. A soil sample was collected at the bottom of each <br /> hole using a slide hammer loaded with a 6" brass sample sleeve. Samples were covered with teflon <br /> sheets, capped with phistic end caps, and sealed with duct tape. The samples were then placed in a <br /> cooled ice chest. Samples were transmitted to Excelchem Environmental Labs of North Highlands <br /> for analysis of organochlorine pesticides (EPA method 8080). The borings were backfilled with a <br /> cement grout slurry at the direction of Mr. lnfurna. <br /> _ I <br /> I <br /> 4.0 LABORATORY RESULTS <br /> None of the samples obtained November 19 contained detectable levels of pesticide compounds <br /> (Appendix A). After discussing the results with Ms. Snell, Upgradient was given pernnission to <br /> return and obtain a sample as close as possible to the location where the highest levels of <br /> contamination were found by RESNA. On December 10, Upgr-adient personnel obtained SP-6 <br /> from a depth o 4.5 et as near as possible to the area where RESNA obtained B-4 (Figure 2). <br /> SP-6 was tested for organochlorine pesticides, petroleum hydrocarbons as diesel and total oil <br /> and grease. The tests found no contamination of hydrocarbons or pesticides. <br />
