Environmental issues
Keystone Sanitation Landfill is located on a ridge of 40 acres of former farmland. From 1966 until 1990, it accepted municipal and industrial wastes and construction debris. The site leached volatile organic compounds and heavy metals, and runoff went in all directions into the ground- and surface water, affecting 2,300 people living in a three-mile radius. EPA added the landfill to the superfund list in July 1987. From 1990-1997, cleanup consisted of extraction and treatment of on-site groundwater, installation of an impermeable cap, a landfill gas collection system, construction of a fence, and water monitoring. In 1999, 34 residences in proximity received whole-house treatment units, and groundwater was also extracted off-site. In May 2003, a landfill gas extraction system was added. Because flow rates were too low, 14 additional landfill gas wells were installed in November 2010.[6]
In September 1993, EPA tried to recover approximately $1.4 million of clean up costs in litigation, which as of 2015 was still stayed, pending court-ordered settlement negotiations. The three owners of the landfill, Waste Management Inc., the Keystone Sanitation Company, and Anna and Kenneth Noel refused to participate in clean up and in 2000, EPA fined them $250,000.[6]
