Superfund Site: PMC GROUNDWATER
PETOSKEY, MI

Superfund Site Profile

SITE BACKGROUND

The Petoskey Manufacturing Co., or PMC, was located at 200 W. Lake St. in Petoskey and contained a die casting plant from the 1940s and a painting operation from the mid- to late-1960s. Disposal of spent solvents and paint sludge onto the ground outside the PMC building contaminated soil and groundwater in the vicinity of the site. “Groundwater” is an environmental term for underground supplies of fresh water. A mass of contaminated groundwater – called a “plume” – moved to a nearby well called the Ingalls Shore Municipal Well. The Ingalls well provided drinking water to city residents. Water from the well contained volatile organic compounds, or VOCs. The primary VOC was a chemical called trichloroethylene, or TCE.

The Petoskey Municipal Well Field provided drinking water until late 1997. PMC stopped operating its facility in 2001, and in 2006 the city of Petoskey removed the Ingalls Well. The city has replaced the contaminated well with a new groundwater source, so Petoskey residents no longer consume drinking water affected by PMC pollutants.
