Superfund Site: PALERMO WELL FIELD GROUND WATER CONTAMINATION
Superfund Site Profile
The Palermo Wellfield Ground Water Contamination site is located east of Interstate 5 in Tumwater, Washington. In 1993, the City of Tumwater detected trichloroethylene (TCE) in three of the city’s drinking water supply wells; the city subsequently removed the impacted wells from service. The source of the TCE was determined to be from industrial operations from former and current Washington Department of Transportation (WSDOT) facilities. In addition, a dry cleaning facility operation contaminated groundwater with tetrachloroethylene (PCE). Following cleanup, operation and maintenance activities, monitoring, and remedy optimization are ongoing.
