Working To Restore Nature Soil sampling, in conjunction with tank removal, detected petroleum product constituents in the samples from beneath Tank No 2 (Table 1) The constituents detected in the soil samples are typically derived from gasoline On August 13 & 14, 1990, RESNA (formerly WaterWork Corporation) drilled, logged, and sampled soil bonngs near the former UST location and installed a groundwater monitoring well ' in the approximate center of the former tank location (Figure 2) One soil boring (SBI) was drilled to 65 feet Three soil borings (SB2, S133 and S134) were dnlled to 30 feet, and the fifth ' soil boring was drilled to 80 feet below grade and subsequently completed as a groundwater monitoring well (MWI) ' Laboratory analysis of the soils encountered in MWI, directly beneath the previous tank pit indicated high levels of gasoline hydrocarbons at depths between 10 and 20 feet The concentrations of gasoline hydrocarbons dropped off significantly with depth due to the low permeability of the soils Monitoring well MWI and soil boring SB2 samples contained ' significant amounts of hydrocarbon constituents Soil samples collected from soil borings SBI, S133 and S134 contained trace to very low concentrations of gasoline range analytes Soil ' contamination is assumed to extend beneath the mausoleum adjacent to the former tank locations Table 1 summarizes soil analytical results In the analysis of the initial groundwater sample collected from monitoring well MWI, on August 23, 1990, elevated levels of petroleum hydrocarbon analytes were detected Table 2 summarizes groundwater analytical results On May 5 and 6, 1992, RESNA supervised the installation of two soil borings (MW2 and MW3) which were drilled to 76 feet below grade to provide for the installation of groundwater monitoring wells Drilling was conducted by Spectrum Exploration, (C57 license #512268) ' using a hollow-stem auger drill ng Cored soil samples were collected above and below the - water table at 5-foot intervals Selected soil samples were analyzed for benzene, toluene, ' ethylbenzene, and xylenes (BTEX) utilizing EPA method 8020 and total petroleum hydrocarbons 1500411REPORTSISR-0694 IFNL 4
