AGkdL <br /> 3.1.3 Kleinfelder Sampling <br /> As the environmental contractor to the RP (Lyon Communities) Kleinfelder conducted <br /> soil sampling at the French Camp site during May 1989 to confirm the extent of <br /> contamination prior to cap installation. Eighteen samples were located around the <br /> perimeter of the French Camp site (the site now consisting of both the Equina and the <br /> Thomas properties [6.12 acres total]) to confirm that contamination did not extend <br /> beyond the site boundaries. For each location, a sample was also taken 10 feet within the <br /> property, for comparison. Finally, six locations within the property were sampled. <br /> These samples were collected according to a sample plan reviewed and accepted by the <br /> EPA(21). <br /> 3.2 EPA Sampling <br /> The EPA Technical Assistance Team (TAT) conducted sampling at the Equinoa site on <br /> April 6, 1988(3). <br /> 3.2.1 Purpose and Description of Sampling Event <br /> A total of four on-site surface samples were collected (including one duplicate). One <br /> subsurface composite sample was collected; four off-site samples were collected, three <br /> immediately adjacent to the site, and one background sample 0.4 miles to the north (3). <br /> The sampling objective of the event was to document the existence of a CERCLA <br /> 1 P g <br /> hazardous material on-site to enable EPA to determine whether a federally funded <br /> removal action was mandated according to 40 CFR Section 300.130, since the RP had not <br /> cooperated with prior state and county orders issued with regard to site cleanup (3). <br /> The sampling was conducted under emergency response authority, following Cal EPA <br /> DTSC°s request for assistance in March 1988 (13). The following samples were collected <br /> (see Figure 4, Sample/Boring Location Map): <br /> I-1: Surface composite of soil and debris <br /> I-2: Duplicate of I-1 <br /> II-3: Surface composite of soil and debris <br /> III-4 Surface composite of soil and debris <br /> B-5: Subsurface composite of contaminated soil <br /> 6: Soil, south of site; ploughed field <br /> 7: Soil, southwest of site; ploughed field <br /> 8: Soil; dirt road next to site <br /> 9: Background; 0.4 miles north of site. <br /> URS Consultants, Inc.
