(MAI) a State of California <br /> Department of Health Services (DHS)-certified laboratory. <br /> Selected samples were analyzed for: <br /> • Total petroleum hydrocarbons quantified as gasoline, diesel and motor oil (TPH-g, TPH-d <br /> r and TPH-mo) in accordance with EPA Methods 8015/5030 Modified and 8015/3550 <br /> Modified; <br /> ►. • Oil and Grease in accordance with EPA Method 9070; <br /> • Volatile organic and fuel oxygenated compounds in accordance with EPA Method 8260 <br /> Modified; <br /> • Polychlorinated bi-phenyls (PCB) in accordance with EPA Method 8080; <br /> r • LUFT metals - Cadmium, Chromium, Lead, Nickel and Zinc in accordance with EPA <br /> Method 6010; and <br /> • Hexavalent Chromium in accordance with EPA Method 7196. <br /> r <br /> i. RESULTS <br /> Petroleum hydrocarbons were detected in each soil sample collected. TPH-g was detected in the soil <br /> r samples collected beneath the USTs and fuel dispensers at concentrations as high as 4,300 <br /> milligrams per kilogram(mg/kg). TPH-d and TPH-mo were detected in samples collected beneath <br /> the former waste oil UST and fill location and from the stockpile soil samples at concentrations as <br /> r high as 1,800 mg/kg. Oil and grease was detected in the soil sample collected beneath the former <br /> waste oil UST at a concentration of 3,900 mg/kg. Soil samples collected beneath the fuel USTs and <br /> dispensers were not analyzed for TPH-d, TPH-mo and Oil and Grease. <br /> Toluene was detected in all UST and dispenser samples at concentrations as high as 99 mg/kg(T3- <br /> E). Ethylbenzene and total xylenes were detected in the soil samples collected beneath the USTs at <br /> concentrations as high 200 mg/kg and 1,100 mg/kg, respectively. <br /> r Total lead was detected in all of the soil samples at concentrations as high as 39 mg/kg. Chromium, <br /> nickel and zinc were detected in the soil samples collected beneath the waste oil UST, fill location <br /> and the stockpile at concentrations as high as 40_mg/kg, 34 mg/kg and 330 mg/kg, respectively. <br /> r Hexavalent chromium and PCB's were not detected at or above laboratory reporting limits in the soil <br /> samples analyzed. <br /> r <br /> Advanced GcoEnvironmen[al,Inc. <br /> bw <br />
