Superfund Site: MILL CREEK DUMP

Superfund Site Profile

The Fifth Five-Year Review (September 2016) (PDF) has been posted online.


Construction of the remedy for the Millcreek Dump site was completed in September 2001 and the site is now in long-term operation and maintenance.  The remedy for the site consisted of the construction of an engineered cap on top of the former landfill (which was then contoured to allow a golf course to be installed on top), a flood retention basin and the creation of eight acres of wetlands on property adjacent to the Site. The remedy also includes the extraction and treatment of contaminated groundwater, which, after treatment, is discharged into Marshall Run, an adjacent stream that feeds into Lake Erie. Since October 2007 the treatment plant has been operated by the Pennsylvania Department of Environmental Protection (PADEP).
