matter, but no hydrocarbon odor was observed. 4.2 Laboratory Results of Soil Samples The analytical results are summarized in Tables 1 & 2 . The laboratory .report and chain of custody are attached in Appendix A. TPH as gasoline, TPH as diesel, and BTE&X were not detected in the soil samples from borings 1 through 5. However, total lead was detected in sample B3-20 at a concentration of 44 mg/kg. This sample was re-run in accordance with EPA WET method for soluble lead. Soluble lead was not detected. At the request of the client, three additional samples were analyzed for total lead concentrations. All three (B1-30, B2-30, and B3-30) contained lead at typical background concentrations (4 .8 , 3 . 5, and 4 . 2 mg/kg) . TRPH was detected in samples B6-5, B6-10 and B6-15 at concentrations of 230 gg/g, 110 µg/g and 7 . 6 gg/g (ppm) respectively. 4.3 Laboratory Results of Water Samples Chloromethane (methyl chloride) was detected in the sample from the domestic well at a level of 1. 4 ppm. No other contaminants were detected in this sample (Appendix B) . 5. 0 CONCLUSIONS & RECOMMENDATIONS In the areas where borings were drilled, the site is underlain by relatively fine-grained, low-permeability silt and clay in the upper 30 feet. A few thin, fine-grained sand beds are interbedded. Very little evidence of hydrocarbon vapors was detected during drilling, and no hydrocarbon contamination was detected in samples collected from beneath the three underground storage tanks. One sample from beneath the tanks contained lead at a concentration above normal background levels for this area, but the lead appears to be insoluble and was not detected when analyzed according to Waste Extraction Test methods. GeoAudit recommends that the tanks be removed in accordance with state and local guidelines. Oil was detected in the samples from the location of the above- ground waste-oil tank. Moderate contamination was detected in samples from depths of 5 and 10 feet, but diminished to low levels at 15 feet. Geological Audit recommends that a backhoe be utilized to excavate and remove the contaminated soil in this area. The volume of impacted soil is probably less than 100 cubic yards. Chloromethane was detected in the water sample from the domestic well, but at a level only slightly above the minimum detection level (MDL) . Currently, chloromethane is unregulated for Maximum 4
