Site Background Information: Ralph's Square-Bui AGE-NC Project No. 07-1537 ' Page 3 of 4 ' concentrations ranging from 0.007 mg/kg (sample 132-50) to 40 mg/kg (sample B140). Tertiary butanol (TBA), was detected in one of nineteen soil samples at a concentration of 0.26 mg/kg (sample B3-30). ' Di-isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether (TAME), ethylene dibromide (EDB) and 1,2-dichloroethane (1,2-DCA) were not reported ' in any of the soil samples submitted for analysis. In May 2007,six soil borings were advanced at location CPT-1 for cone penetrometer testing;CPT-1 ' was located approximately 12 feet north of monitoring well MW-3 (Figure 2). A total of four grab ground water, and four soil samples were submitted to a Department of Health Services (DHS) - approved laboratory for analysis. • TPH- g was reported in all four of the grab ground water samples at concentrations ranging ' from 140 micrograms per liter (µg/1)to 1200 µg/1. • BTEX compounds were reported in all four of the grab ground water samples at concentrations ranging from 1.8 gg/l to 25 µg/1 benzene, 7.5 µg/1 to 140 gg/1 toluene, 1.8 gg/1 to 34 µg/1 ethylbenzene, and 8.3 µg/1 to 193 µg/1 xylenes. • MTBE was reported in all four of the grab ground water samples at concentrations ranging from 1.4 µg/l to 150 µg/1. • TPH-g was reported in one soil sample at a concentration of 710 milligrams per kilogram ' (mg/kg)- • BTEX compounds were reported in three of the four soil samples at concentrations ranging from 0.021 mg/kg to 1.7 mg/kg toluene, 9.0 mg/kg ethylbenzene, and 0.016 mg/kg to 91mg/kg xylenes. • MTBE was reported in two of four soil samples at concentrations of 0.030 mg/kg,and 0.010 ' mg/kg. In June 2007 three soil borings (MW4,MW5 and MW6)were advanced by All Well Abandonment ' at the site.The borings were sampled and then completed as ground water monitoring wells,MW-4, MW-5 and MW-6.A total of fifteen soil samples were submitted to a Department of Health Services ' (DHS)-approved laboratory for analysis.No constituents of concern were detected in any of the soil samples collected from borings MW4,MW5 and MW6. The ground water monitoring network has been monrtored six tirr� s;nce_`_The highest concentrations of dissolved hydrocarbons were ' detected at wells MW-2 and MW-3,near the northeast and southeast corners of the former UST area. Low concentrations of petroleum hydrocarbons and fuel additives were detected in well MWA, generally located up-gradient from the former UST area. Advanced GeoEnvironmental,Inc.
