Total Petroleum Hydrocarbon (TPH) compounds being present from prior tank operations in that area. Soil samples were collected at depths of 15, 20, 25, 30 and 35 feet below ground surface (bgs)using a split spoon drive sampler with brass liners. The ends of the liners were covered with teflon sheets prior to sealing with plastic caps. A signed copy of the boring log is attached. Soil samples were logged for fithology and field screened for the presence of volatile petroleum hydrocarbon compounds. Samples from each sampling depth were also retained for chemical analyses for TPH as gasoline, BTEX and total lead using the above referenced methods. Samples were labelled with the project number, sample number, sampler name, date, boring number and depth. Samples were handled using appropriate Chain of Custody and were transported to Anlab Analytical Laboratory for analyses. The test results are tabulated below and copies of the laboratory reports are attached. The borehole was abandoned under the direction of Ms. Margaret Lagorio, Senior REHS from San Joaquin County PHS/EHD using a Portland Cement mix. A copy of the completed boring application is attached. Groundwater Sampling and Analyses Three on site groundwater monitoring wells, SRK-MW-1, SRK MW 2 and SRK-MW-3, were purged and sampled on April 26, 1994 and May 26, 1994,using new disposable teflon bailers. Purging consisted of removing an equivalent of three well volumes from each monitoring well prior to sampling. Collected groundwater samples were analyzed for TPH as gasoline, BTEX, and total lead using the above described analyses. Samples collected for TPH and BTEX analyses were collected in 40 ml. VOA vials with teflon septa. Samples for lead analyses were collected in 500 ml. plastic bottles. Samples collected for lead analyses were field filtered. Sample collection and filtering for both sampling events were performed by Anlab personnel. Analytical test results are tabulated below and copies of the laboratory reports are attached. Analytical Test Results Soil and groundwater samples were analyzed for TPH as gasoline, BTEX and total lead. Both soil and groundwater samples were non-detect for TPH and BTEX at the method detection limits of 20 and 0.5A respectively. Total lead concentrations in the soil samples ranged from 0.72 mg/kg to 6.9 mg/kg, which are typical of background levels in the San Joaquin Valley. Total lead levels for the groundwater samples were non-detect at the method detection limit of 1.0 µg/l. CONCLUSIONS • The underground storage tank area at 224 North Main Street, Lodi, California has been remediated. • The soil samples collected from beneath the tank excavation pit were non-detect for TPH 501611 3
