' detected in water samples collected from boring P32 at 100 feet bsg,at concentrations of 440 • and 140 gg/l, respectively. ' TPH-d was detected in water samples collected from boring P32 at 60 and 100 feet bsg, at concentrations of 230 and 330 µg/1, respectively. ' TPH-g and TPH-ss were detected in water samples collected from boring P33 at 80 feet bsg, at concentrations of 680 and 210 µg/1,respectively. TPH-d was detected in the same water sample collected from boring P33 at a concentration of 230 µg/1. ' BTEX compounds were detected in the ground water samples at concentrations as high as 760 gg/1(P32-60,xylene). Benzene was detected in the ground water sample from P32-60 at a concentration of 96 µg/1 . • 1,2-DCE was detected at a concentration of 1.4 µg/1 in the water sample collected from P30 at a depth of 100 feet bsg and 1,2-DCA was detected at a concentration of 25 µg/1 in the grab ' ground sample collected from P33 at approximately 80 feet bsg. • No other petroleum hydrocarbon constituents or fuel oxygenated compounds were detected ' by the laboratory analyses. • Limited analytical results of the soil samples are depicted on cross section C-C'(Figure 3). This interpretive cross section has been re-drawn with greater weight given soil classification from hand samples and with interpretation of CPT data utilized for un-sampled or less sampled intervals. • Analytical results from soil samples are summarized in Tables IA, 1B and 1C. • Analytical results of the grab ground water samples are depicted In Table 2A. January 2001 - Installation of Ground Water Monitoring Wells. On 24 through 26 January 2001, seven soil borings were established for the collection of soil samples and installation of ground water monitoring wells.Fourteen soil samples collected from the ' monitoring well pilot soil borings were analyzed for TPH-g, TPH-d, BTEX, and fuel additives including MTBE and HVOCs; petroleum hydrocarbons and HVOC's were not detected in the soil ' samples. Analytical results from soil samples are summarized in Tables IA, 1B and 1C; limited analytical results of the soil samples are depicted on cross section C-C'(Figure 3).The well construction details are summarized in Table 3. February 2001 - Sampling of Monitoring Wells. ' The initial monitoring and sampling of wells MW-1 through MW-7 occurred on 05 February 2001; • the initial findings indicate: Advanced GeoEnvironmental,Inc.
