DEP is maintaining exhaust fans on the sanitary sewers to remove the vapors from that system. In addition, DEP installed a temporary vapor extraction system near a home on Harmony Road, which enabled the family to return to the home Nov. 3. All families are currently back in their homes. Last week, the station's contractors removed a diesel fuel tank full of holes. DEP contractors removed a gasoline tank with holes yesterday.
Work continues today to remove at least three additional tanks and contaminated soil.
DEP contractors will be installing a groundwater collection and treatment system to prevent the gasoline already in the ground from further discharging into Girty's Run. A vapor extraction system also will be installed to protect the homes along Harmony Road from the gasoline fumes. DEP also is working with the Allegheny County Health Department to monitor the drinking water wells of four homeowners. Samples were taken last week.
