From 1972 to 1976, the 108-acre site was owned and operated by Compass Industries. Although permitted as a sanitary landfill, it may also have received an unknown quantity of hazardous wastes.
Underground fires are a problem at the facility.
Liquid waste seeping to the surface at the landfill contains PCBs, according to analyses conducted by the State. Surface run-off and possible ground water contamination are concerns, as are air releases from the fires. The description may change as additional information is gathered on the sources and extent of contamination.
