Problems/Comments

Last Update: November 8, 2017 The West Perimeter Road TCE Spill (Site SS025) is located along West Perimeter Road and is almost entirely within the boundary of Site CG001. The Alaska Department of Transportation and Public Facilities (ADOT&PF) owns West Perimeter Road within the right-of-way and both ADOT&PF and the City of Galena own adjacent parcels. Residual Soil Contamination does not pose a threat to human health or the environmment. No groundwater COCs were identified for Site SS025. Diesel-range organics (DRO), residual-range organics (RRO), and benzene contamination exists in groundwater beneath Site SS025 in the variably saturated zone and the permanently saturated zone; this contamination is attributed to Site CG001 and is being addressed by the remedy for that site.
