ETS ENVIRONMENTAL <br /> PAGE <br /> The field identification numbers assigned to the samples <br /> are explained. as follows: <br /> lows: <br /> PROJECT NUMBER DATE BORING DEPTH <br /> 301 062188 1 * A .. <br /> 3G 1 i_162188 1 * B <br /> 3u1 062188 1 15 <br /> * <br /> Note: In all cases "A" denotes a five foot sample <br /> and "B" denotes a ten foot sample. <br /> Borings 1 and 2 were analyzed for diesel, and borings 3 <br /> through 6 were analyzed for gasoline, ba=th using EPA method <br /> 8015 modified. Detection lir`iiits for the diesel analysis are <br /> 1. 0 mg/kg (ppm) and for the gasoline are 0. 5 mg/kg (ppm) . <br /> Laboratory results and the Chain-Of-CUstOdy documents are <br /> attached as Appendix B. <br /> The protocol followed during the dri.l 1 ing and sampling <br /> operation has been attached to this report as Appendix C. <br /> 3. 0 FINDINGS <br /> Based on field observations and laboratory^ data ETS <br /> Environmental has made the following findings: <br /> i. Barings i through. 5 to a depth of fifteen feet <br /> indicate that no gasoline or diesel leakage has <br /> occurred in, the proximity of these borings. <br /> 2. Gasoline tainted soil in the proximity of boring 6 <br /> does existat the._ ten foot depth in a quantity below <br /> the reportable level. The gasoline is reported as <br /> heavily weathered by the lab and may indicate an old <br /> VQ1"I surface spill or that a tank previously located here <br /> leaked. <br /> 3 A gases 1 i'r�e odor' was" detected in the soil between two <br /> and ten feet in boring , 6 but due to the <br /> Q �_inc��r�ao l i da ed nat ur,e_ of_ the soi1, sample recovery <br /> at five.. feet. was- n1:A possible.
