ANALYSES AND RESULTS <br /> 3.1 Chemical Analyses <br /> The soil and ground water samples taken from the test borilt"s were analyzed for the <br /> fol lowing: <br /> • Total Petroleum Hydrocarbons as Gasoline + MTBEX, Total. Petroleum <br /> Hydrocarbons as Diesel, Kerosene, Motor Oil, Stoddard Solvent (TPH-g + <br /> MTBI-,X, TPH-d,TPH-k,TPH-nio,TPI-1-ss) (Modified EPA 8(.150); <br /> • Halogenated Volatile Organic Compounds (HVCK's)(EPA Method 8010);and <br /> • 1..11Fr Metals (EPA 6010). <br /> As part of a screening measure, the soil samples collected from 5, 10 and 15 ft. bgs. <br /> frorn each of the boring locations were composited (3:1). Although compositing is <br /> less expensive than collecting individual samples,the method still has its drawbacks_ <br /> For example, positive results from composites do not determine which sample <br /> depths (5, 10 or 15 ft, bgs.) were positive for a particular exploratory boring. <br /> 3.2 Analytical Results <br /> Results of chemical analyses on the soil samples collected on May 6, 2003 are presented in <br /> Tables 1 and 2. Results of chemical analyses on the grab water sample collected on May 6, 2003 <br /> are presented in Tables 3 and 4. Certified laboratory reports are presented in Appendix 13, including <br /> chain-of-custody record data. <br /> Table 1.
