In December 1989 five soil borings and three long-term monitoring wells (MW-1, MW-2, and MW-3), were sampled to help assess for soil and groundwater contamination at this site. The soil and groundwater samples were analyzed for BTEX and TPH(RRO). Up to 0.026 mg/kg benzene and 348 mg/kg TPH in the soil samples collected. Up to 401 ug/l benzene, 25 ug/l toluene, 64 ug/l ethylbenzene, and 154 ug/l xylenes in the groundwater samples collected. |

Document, Report, or Work plan Review - other |
Vapor intrusion and groundwater monitoring report submitted for field activities in September 2023. Groundwater samples were collected from MW-7 and tested for GRO, VOCs, and PAHs. No contaminants exceeded groundwater cleanup levels. Indoor air and 3 subslab soil gas samples were also collected. A variety of compounds were detected in these samples which are likely associated with use of the building as a car wash, automotive shop, and laundromat. All indoor air and soil gas results were below DEC commercial target levels. One subslab soil gas sample, collected from the western portion of the building, contained PCE above residential target levels. |
