I <br />' On 04 November 1999, six soil probe borings (PB 1 through PB6)were advanced at the site under <br /> EHD oversight Probe borings were advanced in the area of the former USTs, dispenser and <br /> northwest to the property line, a total of 11 soil samples were submitted for analysis In addition, <br /> grab ground water samples were collected from borings PB-1, PB-4 and PB-5 and were submitted <br /> for analysis <br /> • Only soil samples from PB-4 contained detectable concentrations of BTEX compounds <br /> ranging from 0 006 mg/kg to 0 099 mg/kg No other analytes were detected above laboratory <br /> reporting limits <br /> • TPH-g, TPH-d and BTEX compounds were detected in all three ground water samples at <br /> concentrations as high as 100,000 µg/l, 36,000 µg/1 and 11,000 µg/l, respectively <br /> On 18 and 19 November 1999 two groundwater monitoring wells(MW-4 and MW-7)were installed <br /> Ion-site A total of 4 soil samples were submitted for analysis <br /> • TPH-g,TPH-d and BTEX compounds were detected in only the 5-foot soil sample collected <br /> I from MW-4 at concentrations of 940 mg/kg,270 mg/kg,9 6 mg/kg,9 8 mg/kg,20 mg/kg and <br /> 48 mg/kg, respectively <br /> I On 13 March 2001, two soil borings (CPT-1 and CPT-2) were advanced on-site utilizing CPT <br /> technology to model the geological and hydrogeological framework and to assess the vertical extent <br /> of dissolved petroleum-hydrocarbons beneath the site A total of four"grab"groundwater samples <br /> . were collected from CPT-1 and CPT-2 and submitted for laboratory analysis <br /> • TPH-g,TPH-d and BTEX compounds were detected only in the water sample collected from <br /> CPT-2 (61 to 65 feet bsg), at concentrations of 110µg/1 TPH-g, 85 µg/1 TPH-d, 2 4 µg/l <br /> benzene, 3 3 µg/1 toluene, 1 3 µg/l ethylbenzene and 5 9 µg/l total xylenes Laboratory <br /> analysis of grab ground water samples collected from CPT-1 at depths of 26 feet to 30 feet, <br /> I did not report any of the analytes at or above laboratory reporting limits Fuel oxygenated <br /> compound were not detected in the ground water samples <br /> To date,seventeen ground water monitoring events have been conducted at the site The lateral and <br /> vertical extent of impacted soil and the lateral extent of impacted shallow ground water at the site <br /> I have been defined in all directions The vertical extent of deeper impacted ground water has been <br /> defined toward the north and is fairly well defined in the southern portion of the site <br /> I <br /> I <br />
