Palermo Well Field Ground Water Contamination is a federal Superfund site in Washington. The Superfund program, created by Congress in 1980, addresses sites where hazardous substances have been released or threaten release into the environment. EPA scores potential sites using the Hazard Ranking System; those that score high enough are placed on the National Priorities List.
Current status: Construction complete. Physical construction of the cleanup remedy is complete, though long-term monitoring and institutional controls typically continue for years or decades. Groundwater treatment systems, for example, often run long after surface cleanup finishes.
Contaminants of concern include tetrachloroethene, trichloroethene. Contamination has been detected in air, soil, groundwater, surface water, soil gas.
