Water Sam lin Procedure <br /> A water sample was collected from the monitoring wells MW-1 and MW-2 on <br /> October. 1, 1985, The well was developed and <br /> P purged with an air-driver bladder pump. <br /> After approximately five well volumes had been removed, a water sample was collected <br /> in sample bottles provided by the testing Iaboratory. The sample bottles were <br /> +� immediately sealed andlaced,.i � <br /> P n a refrigerated container.

The soil samples collected from the borings in the water samples were analyzed <br /> s by APDL Laboratories for volatile aromatic hydrocarbons using EPA Method 601 EPA <br /> C rocar ! { <br /> a € � ?Method 602, and total hydrocarbons using GC/FID as requested by the County <br /> ' a � representative. Analytic results are presented in Appendix B. <br /> A ' i <br /> VI. Discussion <br /> s � <br /> Gasoline constituents were detected at the 4R.-foot Ievel in the soil sampled from <br /> boring B-1, adjacent to the former tank location. Gasoline constituents were below <br /> detectable limits in the soil sampled from Boring 8-2, away fromm the former tank <br /> site. <br /> +- Water sampled from monitoring well MW-1, adjacent to the tank, showed very <br /> high levels of benzene, ethyle benzene, toluene, xylene, and 1-2-dichloroethane.
