Contamination was found in both the soil and the <br /> groundwater and consisted primarily of diesel fraction (soluble <br /> portion) believed to be from an old pipeline spill. Small amounts <br /> of gasoline (0.4 ppm) , diesel (36 ppm) , and benzene (1. 1 ppb) were <br /> found in the groundwater. <br /> After the wells were developed and the initial round of groundwater <br /> sampling was completed, MW-2 was purged of all contamination and <br /> retested. The results of this second round of testing are enclosed <br /> and clearly show a reduction in contamination levels in MW-2 . No <br /> benzene or other volatile aromatics were detected and the TPH <br /> levels were reduced to 26 ppm. <br /> We believe that with removal of the contaminated soil, water <br /> contamination should be significantly reduced if not eliminated <br /> entirely. <br /> Sincerely, <br /> oxicATechnology,, Inc. <br /> 3 Adam P.
