Forest Township Library, 130 E Main Street, Otisville, Michigan


The Forest Waste Products (Forest Waste) site is located in Forest Township, Genesee County, Michigan. The original site area encompassed 112 acres. The site was later expanded to include an additional 80-acre parcel in September 2005. Waste disposal areas located on-site include an 11-acre landfill and nine former lagoons that span a total of one acre. The site is surrounded by low-density residential development, farmland, wetlands, wood lots, a gravel quarry, and a small lake.

he site owners received a license from the state of Michigan in 1972 to dispose of general refuse and industrial and liquid waste. Wastes were accepted between 1973 and 1978. Wastes containing polychlorinated biphenyls (PCBs) and polybrominated biphenyls (PBBs) are documented to have been disposed of in the landfill. Soils in the former lagoon area were contaminated with metals, PCBs, and volatile organic compounds (VOCs). The state did not renew the license in 1978 due to operational and other various violations.

Area residences use private wells for drinking water. The subsurface groundwater sampling conducted through 1994 defined groundwater contamination as limited to the original site area east of the landfill and in the vicinity of the lagoons.  In December 1995, groundwater contamination by VOCs was detected north of the landfill and outside the original site area. Later sampling has showed that the groundwater contamination from north of the landfill extends beyond the additional 80-acre parcel that was added to the site.

Site Updates

October 2012 Update

U.S. EPA fenced the site in 1984, conducted sampling to locate the soil and groundwater contamination from 1983 - 1992, and evaluated methods to cleanup the site from 1986 - 1993.  Private parties who may be responsible for the contamination performed the other work under U.S. EPA and state agency oversight. Prior to 1994, the private parties removed wastes from the lagoons and landfill and initiated groundwater sampling. In accordance with a 1994 agreement, the private parties are responsible for all of the remaining cleanup work, including covering the landfill with a soil cap, treatment of the contamination north of the landfill, sampling groundwater, and other monitoring. Private parties must also reimburse federal oversight costs.

U.S. EPA completed five-year reviews in 1997, 2002 and 2007.  The 2007 five-year review identified concern about methane contamination from the landfill, and with entry of the oxidant into the lake.  These concerns were addressed by adding dissolved methane to the groundwater monitoring, monitoring for oxidant at the ends of the injection lines closest to the lake and eliminating injection points nearest to the lake where oxidant was detected.

A fourth five year review was completed and signed in 2012 and is attached to this site below.
