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.

May 2015 Update
EPA continues to monitor for site chemicals in the groundwater. Groundwater sampling originally defined groundwater contamination as limited to the original site area and east of the former landfill; however, later sampling has shown that the contamination extends to the north and west.
All residents in the area use residential wells for drinking water and EPA requested that the potentially responsible party evaluate any off-site groundwater impacts from the site. Early this year, samples were collected for volatile organic compounds (VOCs) and 1,4-dioxane from 15 residential wells. Six of the wells are shallow and showed low levels of 1,4-dioxane, but no contaminants were detected above the State’s drinking water criteria. The remaining residential wells were deep wells in the bedrock aquifer and showed no detections. For those residents with low detections in their shallow wells, the potentially responsible party took proactive steps to offer replacement wells. New wells would be drilled into a much deeper, bedrock aquifer. That effort is currently ongoing, as are the investigations to define the full extent of the plume.
Once the investigation is complete, EPA will develop a plan to address the off-site migration of 1,4 dioxane contamination. EPA will share details with the community as soon as this summer.
