k4 KLEINFELDER <br /> C~ 8 LIMITED SOIL SAMPLING <br /> 8.1 BACKGROUND <br /> Based upon the historical agricultural use of the site, Pegasus Development requested soil <br /> sampling to assess the potential of residual organochlorine pesticides in near surface soils at the <br /> subject site. <br /> 4 The following report documents Kleinfelder's findings. <br /> Field Activities <br /> On May 17, 2005, Five (5) discrete hand auger soil samples (Sl through S5) were collected at <br /> the subject site. The soil samples were located in approximately equal portions of the site over <br /> the subject site area (Plate 2). Kleinfelder advanced one soil boring per approximately every 2.5 <br /> -acres. <br /> One sample was collected from each location, at an approximate depth of 0 to 6-inches below <br /> ground surface (bgs). Grasses, weeds and miscellaneous vegetation were removed prior to <br /> collecting the discrete soil samples. <br /> Soil samples were obtained by slide hammering a 2-inch diameter by 6-inch long stainless steel <br /> tube into the soil at the desired sampling depth. The stainless steel tube was then removed from <br />` the soil and sealed with Teflon sheeting and tight-fitting plastic end caps. The sampling <br /> equipment was cleaned between sample locations with a Liquinox@ (laboratory-grade detergent) <br /> and potable water wash followed by a distilled water rinse. New stainless steel tubes used for <br /> sample collection were also cleaned using the same methodology. <br /> The samples were labeled, logged on to a chain-of-custody form, and immediately stored in an <br /> iced cooler. The samples were transported under chain-of-custody control to Precision Enviro- <br /> 1 + Tech Analytical Laboratory of Stockton, California for chemical analysis. Precision Enviro- <br /> Tech Analytical Laboratory is certified by the California Department of Health Services (DHS) <br /> to perform the requested analyses. The laboratory data sheets and chain-of custody records are <br /> included in Appendix E. <br /> j The soils encountered in the soil borings were silty sands. No unusual odors or discoloration <br /> was noted during the sampling event. The shallow borings were backfilled with native soil. <br /> 5556S.POI/ST05R488R/LTV:Iv Page 25 of 30 <br /> ©2005 Kleinfelder,Inc. June 1,2005 <br />
