3.1 SOIL SAMPLING <br /> A total of 6 soil borings (SB-I through SB-6) were driven on 3 December 2009, with a <br /> truck mounted mobile Geoprobe® boring rig using nominal 2-inch outside diameter <br /> Geoprobe® casing rods. The soil sampler was driven using a hydraulically actuated <br /> Geoprobe®sample rod with a 48-inch acetate sampling tube inserted within the casing rod. <br /> Soil borings were continuously cored when capable. Soil boring SB-1 was advanced to a <br /> total depth of 23 below ground surface (BGS), borings SB-2 and SB-3 were advanced to a <br /> total depth of 12 feet BGS, boring SB-4 was advanced to a total depth of 16 feet BGS, <br /> boring SB-5 was advanced to a total depth of 21 feet BGS, and boring SB-6 was advanced <br /> to a total depth of 16 feet BGS. A portion (approximately 2-inch section) of each sample <br /> recovered was field screened with a photoionization detector(PID). Soil samples SB-1 at <br /> 12, 16, 19, and 23 feet BGS and SB-6 at 12 and 16 feet BGS resulted in an elevated PID <br /> reading. See Figure 3 for boring logs. <br /> Soil samples chosen for laboratory analytical submission were trimmed flush with the end <br /> of the sleeve, the ends covered with Teflon" film, and then sealed with plastic end caps. <br /> Each sample was labeled and placed into a pre-cooled ice chest at a temperature of <br /> approximately 4°C during transportation to the laboratory. Proper chain-of-custody <br /> protocol was followed at all times. <br /> 4.0 CHEMICAL ANALYSIS <br /> A total of 10 soil samples were submitted for chemical analysis. Each soil sample was <br /> analyzed for total petroleum hydrocarbons as gasoline (TPH-g), total petroleum <br /> hydrocarbons as kerosene (TPH-k), and total petroleum hydrocarbons as diesel (TPH-d) <br /> by Environmental Protection Agency (EPA) Method 8015B, benzene, toluene, <br /> ethylbenzene and xylenes (BTEX) compounds by EPA Method SW8021B. The fuel <br /> oxygenates tert-butyl alcohol (TBA), methyl tert-butyl ether (MTBE), di-isopropyl ether <br /> (DIPE), ethyl tert-butyl ether (ETBE), tert-amyl methyl ether (TAME), and 1, 2 <br /> Dichloroethane and 1, 2 Dibromoethane were analyzed by EPA Method 8260B. Total <br /> lead was analyzed by EPA Method 6010B. <br /> 4.1 ANALYTICAL RESULTS <br /> Analytical results revealed soil samples collected from boring locations SB-1 and SB-6 <br /> contained elevated levels of TPH-k. Soil sample SB-1 at 12, 19, and 23 feet resulted in <br /> concentrations of TPH-k at 0.9 mg/kg, 26 mg/kg, and 1300 mg/kg respectively. Soil <br /> sample SB-6 at 12 and 16 feet resulted in concentrations of TPH-k at 0.33 mg/kg and 120 <br /> mg/kg respectively. All other soil samples were reported with concentrations of <br /> contaminants of concern below their respective detection limits. See Table 1 for soil <br /> sample analytical results. The certified laboratory reports can be found in Appendix A. <br /> 12/22/2009 HANOVER ENVIRONMENTAL SERVICES,INC. 4 <br /> Soil Assessment Report <br /> McHenry Ave Project <br /> 1303 First Street,Escalon <br />
