Please make a note.

The Beacon Heights Landfill site covers 34 acres on an 83-acre property. Between 1920 and 1979, the landfill was used for the disposal of industrial and municipal waste, including oils, chemical liquids, sludges, solvents, rubber, and plastics. Landfill operations included open burning, along with burial of non-combustibles. During a 1984 EPA investigation, benzene and several other solvents were detected in two private wells on Skokorat Road at levels that exceeded drinking water standards set by the State of Connecticut. Approximately 44 homes are located within 1/2 mile of the site along Skokorat and Blackberry Hill Road. The nearest residences lie approximately 1,000 feet to the north and west of the site; 800 people live within a mile of the site. Local residences once used groundwater as the drinking water supply source until they were connected to the municipal water supply in 1989. The local surface water is used for recreational purposes. Hockanum Brook, located 1/2 mile northwest of the landfill, flows into the Naugatuck River 2 miles northwest of the site.

Threats and Contaminants
[Back to Top]

The groundwater underlying the site was found to be contaminated with volatile organic compounds (VOCs) including trichloroethlyne. The on-site leachate and soils are contaminated with VOCs, as well as lead. The on-site surface water had been shown to be contaminated with VOCs. People were once at risk by coming into direct contact with or drinking contaminated surface water or groundwater, breathing potentially contaminated air, or by accidentally ingesting soil on the site. The landfill was capped in 1993-94 and leachate is being collected by a leachate collection system and treated at the local publicly owned treatment facility. These actions collectively reduce risks of exposure, thus making the site safe for local residents.

Cleanup Approach
[Back to Top]

This site is being addressed in two long-term remedial phases focusing on control of contamination sources and cleanup of leachate at the site.

Response Action Status
[Back to Top]

Source Control The remedial action at this site was completed in December 1997. The source control included: consolidating wastes; building a multi-layered protective landfill cap; installing gas vents; and, installing a leachate and seep collection system. A fence surrounds the landfill area. Institutional controls are currently being pursued to prevent the use of contaminated groundwater and to protect the remedial actions that have been established.

Leachate The leachate collected by the leachate and seep collection system is conveyed through a leachate transportation line to the local sewer system, which was rehabilitated for this purpose. The sewer line discharges for treatment to the Beacon Falls Treatment Plant, which was also upgraded for this purpose.

Enforcement HighlightsIn 1987, 32 of the more than 70 companies identified by the EPA as potentially responsible parties agreed to pay for a substantial portion of the site cleanup. In February 1997, this coalition of 32 parties paid the U.S. Government $600,000 in stipulated penalties for not only significant time delays in completing the remedial action, but for erosion and sedimentation violations which occurred during construction as well.

Environmental Progress
[Back to Top]

Local residences are connected to the municipal water line thus providing a safe drinking water supply and reducing the potential for exposure to contamination. The remedial action has been completed including the final construction of the landfill cap and the leachate collection system, making the Beacon Heights Landfill site safer. Additional property was purchased at the foot of the landfill and several acres of wetlands were recreated by the potentially responsible parties to compensate for a few acres that were destroyed and/or damaged during the landfill cap construction. The site is now undergoing a long-term operation and maintenance phase that will continue indefinitely.

Current Site Status
[Back to Top]

This municipal and industrial landfill was listed in 1983. The oversight of the operation and maintenance program continues. It includes a program to monitor the effectiveness of the cap and the diversion system that was constructed to divert clean groundwater and surface water away from the landfill. The most recent five-year review of the site was completed in September 2008. The review concluded that the cleanup actions being implemented at the site remain protective of public health and the environment. Long-term monitoring of the contaminated groundwater and wetlands will continue until the cleanup objectives have been achieved.
