i Domestic Wells According to Mr Joe Toste,Jr ,the property owner,there are two domestic water • wells on Toste Road, one on-site (2450 Taste Road) and the other at 2480 Toste road, these wells I supply water to the site and the businesses located on Toste Road The on-site well is completed to a total depth of 220 feet bsg and contains a well screen from 195 feet to 220 feet bsg, a copy of the well driller's log is included as Appendix A The well located at 2480 Toste Road is approximately 300 feet southwest of the site According to Mr Toste,this well is completed to a total depth of 200 feet No other information could be obtained regarding this well or two other domestic wells observed at 2040 and 2120 Grant Line Road Threatened Well The on-site domestic water well at 2450 Toste Road is located dust beyond the southern margin of the contaminant plume and up-gradient of the former dispensers and UST area This water well was sampled during the first and second quarters of 2002 for total petroleum hydrocarbons quantified as gasoline and diesel(TPH-g and TPH-d),benzene,toluene,ethylbenzene, total xylenes (BTEX) and seven fuel additives None of the analytes were detected at or above Ilaboratory reporting limits in the samples collected IUST REMOVAL ' AGE was informed that three USTs, dispensers and piping were removed from the site on 31 July 1991, and that the removal was witnessed by a representative of the EHD, additional information regarding history of the UST use, tank tests, product inventory and repairs are not known to AGE 10 Six soil samples were collected from the sidewalls during the 31 July 1991 excavation, at a depth of five feet below surface grade (bsg), no excavation floor samples were collected because ' groundwater was encountered in the excavation at a depth of approximately six feet In addition,one grab groundwater sample was collected from the excavation and one soil sample was collected beneath the piping/dispenser area The soil and ground water samples were analyzed for TPH-g, IBTEX, lead and ethylene dibromide (EDB) Concentrations of TPH-g and BTEX compounds were detected in each soil sample collected from Ithe UST excavation TPH-g was detected from the east wall of the UST excavation at a maximum concentration of 62 milligrams per kilogram(mg/kg)and from the west wall of the UST excavation I at a maximum concentration of 26 mg/kg Benzene was not detected above the elevated detection limits in the soil samples collected from the UST excavation walls Lead was detected at a maximum concentration of 10 mg/kg EDB was detected in one sample at a concentration of 2 9 mg/kg ITPH-g and BTEX compounds were detected in the water sample at concentrations of 150,000 micrograms per liter (µg11) and 25,000 µg/1, 43,000 µ.g/1, 5,700 µg/1 and 32,000 µg/1, respectively Lead was detected at a concentration of 0 67 µg/1 in the water sample,however,EDB was not detected 0
