KLEINFELDER water rinse. New stainless steel tubes used for sample collection were also decontaminated using ` the same methodology. ` The twenty-five discrete soil samples were submitted under chain-of-custody control to Sequoia Analytical Laboratories (Sequoia) of Sacramento,California. Sequoia is certified by the State of California to perform the requested analyses. Twenty-four discrete field samples were composted into eight 3-point composite samples by the analytical laboratory. These eight composite samples were analyzed for the following: ♦ Organochlorine Pesticides by EPA Method 8081A The single discrete sample (PMT-1) collected beneath the pole-mounted transformer was analyzed for the following: ♦ Polychlorinated Biphenyls (PCBs)by EPA Method 8082 The samples were submitted on a standard 10 working day turn-around time (TAT). No organochlorine pesticides were detected in the eight 3-point composite samples submitted for analysds at or above laboratory reporting limits. PCBs also were not detected in the single soil sample collected beneath the pole-mounted transformer. Sw,18ampiing in AST Area (March 17, 2003} Kleinfelder initially collected a total of five soil samples in the vicinity of three ABT's on March 17, 2003 (Plate 3). Two of the AST's had an approximate capacity of 2,000-gallons and a smaller tank located at the ground surface had an approximate capacity of 500 gallons. The ` AST's reportedly contained diesel and gasoline. A total of three hand auger borings were advanced in the AST area, one beneath each of the AST's in soil stained areas in proximity to the AST dispenser. The samples were collected at depths ranging from 12-inches to approximately 5%s feet below ground surface (bgs). Each of the five soil samples was noted with soil discoloration and a strong petroleum type odor. The soil samples were obtained using the same _ methodology described in the agricultural soil sampling, including cleaning methods. The two deeper soil samples collected at depths of 5 and 5%2 feet were analyzed for the ` following: • Total Extractable Petroleum Hydrocarbons referenced as Diesel [TPH-D] by EPA Method 8015M/3015. • Total Extractable Petroleum Hydrocarbons referenced Gasoline and benzene, toluene, ethylbenzene and total xylenes (BTEX)by EPA Method 8260. • Total lead by EPA Methods 21073/ST03R7067 July 28,2003 ©2003 Kleinfeldey Inc.
