Background
The 4-acre Wisconsin Public Service Corp. site is located in Manitowoc, Wis. Currently, the majority of the site is occupied by actively used commercial buildings and asphalt parking lots. Residential, commercial and industrial-use properties are found in the vicinity. The Manitowoc River borders the site on the northwest.
WPSC owned and operated the gas plant from before 1900 to the late 1940s in an area that was historically industrial. Processes included coal carbonization and carbureted water gas. WPSC still owns the site today.

Site Updates
March 2009
Plans for investigation of sediment, ground water and soil at six MGP sites began after a legal agreement called a consent order was signed between WPSC and EPA in May 2006. This agreement allows for further investigation of the Manitowoc site and will determine how much contamination remains in soil, sediment and ground water at the site. In 2008, technicians sampled the Manitowoc River and the old plant site.
Another round of sampling is scheduled for this summer. Workers will be trying to get a better idea of where PAH contamination is located. Manitowoc residents may notice workers in protective clothing in and along the river. They will be using small pieces of equipment to take samples while on foot and from small boats. The 2006 agreement
also includes five other MGP sites in Green
Bay, Stevens Point, Marinette, Oshkosh,
and Two Rivers, Wisconsin. A separate
agreement for another site, WPSC Campmarina
MGP in Sheboygan, was signed between WPSC and EPA in January 2007.
Under Wisconsin Department of Natural Resources oversight, various investigations have taken place since the 1988. Some upland cleanup occurred from 1992 to 1994 when highly contaminated soil between the WPSC building and Manitowoc River was excavated and removed from the site or treated in place. Routine ground-water monitoring occurs annually.
