The U.S. Environmental Protection Agency has announced plans to clean up a contaminated, former mill property in Windham. The Keddy Mill complex in Windham has been on the EPA's list of Superfund sites since 2014 after studies found PCBs, heavy metals, petroleum products and other contaminants. The property, which is located in the Little Falls area of the Presumpscot River, had been the site of multiple mills beginning in the mid-1700s. But environmental officials believe much of the contamination stems from the 1960s and 1970s when the Keddy Mill Company made steel products at the site. The EPA will demolish the dilapidated mill structures on the 7-acre site, remove contaminated soils, treat the groundwater, restore a portion of the Presumpscot River, and set up ongoing monitoring of environmental conditions.
