Appendix A - Historical Background • River City Petroleum and Connell Motor Lift Truck Page 7 of 13 Based on the data from CPT soil borings P30 through P33, supplemented with subsequent soil borings MW-1 through MW-6,stratigraphic cross section A-A' was constructed,which depicts the general lithology north to south across the suspected release area. Fourteen soil samples collected from the CPT soil borings were analyzed for TPH-g,TPH-d,BTEX, and fuel additives including MTBE and VOCs. TPH-g,TPH-d and TPH-ss were detected in the soil samples from CPT P32 as follows: • TPH-ss and TPH-g were detected at concentrations as high as 2,300 milligram per kilogram (mg/kg) in soil sample P32-60, TPH-d was detected in the same sample at a concentration of 1,300 mg/kg. • TPH-g and TPH-ss were both detected in soil sample P32-70 at a concentration of 1,800 mg/kg, TPH-d was detected, in the same sample, at a concentration of 2,000 mg/kg. TPH-g and TPH-ss were detected in soil sample P32-78 at concentrations of 41 and 72 mg/kg, respectively. TPH-d was not detected in the same sample. • Toluene, ethylbenzene and xylene were detected,in the above samples,at concentrations as high as 2.6 mg/kg.The volatile organic compound methanol was detected in one soil sample, • P32-60, at a concentration of 310,000 micrograms per kilogram (µg/kg). • Oxygenated fuel additives were not detected in the soil samples analyzed. A total of five "grab" ground water samples were collected from CPT P30 through P33 and submitted for laboratory analysis for the above mentioned constituents. • TPH-g and TPH-ss were detected in the grab water sample collected from boring P32 at 60 feet bsg, at concentrations of 120,000 micrograms per liter(µg/1). TPH-g and TPH-ss were detected in water samples collected from boring P32 at 100 feet bsg,at concentrations of 440 and 140 µg/1, 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/l, 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 µg/l (P32-60, xylene). Benzene was detected in the ground water sample from P32-60 at a concentration of 96 µg/l . • Advanced GeoEnvironmental,Inc.
