The water samples were labeled, placed in a cooler <br />with ice and transported under Chain of Custody (COC) <br />documentation to Mccampbell Analytical. <br />ANALYTICAL RESULTS <br />The soil samples collected were -analyzed for Total Petroleum <br />Hydrocarbons as Gasoline (TPHG); Benzene, Toluene, Ethylbenzene <br />and Xylene (BTEX); and OXygenates. The samples were analyzed for <br />TPHG by EPA Method 8015 modified with purge and trap preparation <br />$030 (GC/FID) with detection limits of 50ug/1. EPA Method 602 <br />will be utilized for-BTEX with a detection limit of 0.5ug/l. <br />The domestic wall and groundwater samples collected were analyzed <br />for Total Petroleum Hydrocarbons as Gasoline (TPHG); Benzene, <br />Toluene, Ethylbenzene and Xylene (HTPX); and Oxygenates. The <br />groundwater samples were analyzed for TPHG by EPA Method 8015 <br />modified with purge and trap preparation $030 (GC/FID) with <br />detection limits of 30ug/l. <br />Table 1 shows the results in Parts Per Million (PPM) of the soil <br />and groundwater sample analysis. <br />TABLE 1 <br />Sample <br />TPHD <br />TSHG <br />H <br />T <br />E <br />X <br />MTBE <br />POT W <br />ND <br />ND <br />NO <br />ND <br />ND <br />ND <br />ND <br />Soil 1 <br />4.1 <br />ND <br />ND <br />ND <br />NO <br />ND <br />ND <br />Soil 2 <br />120 <br />170 <br />ND <br />0.12 <br />NO <br />0.41 <br />ND <br />Soil 3 <br />14 <br />ND <br />ND <br />ND <br />ND <br />ND <br />ND <br />G W <br />21 <br />1 39 <br />0.027 <br />0.035 <br />1 0.14 <br />4.8 <br />1 ND <br />UiT 1,-. -p 11 <br />leLug <br />7j0oe <br />3 <br />
