The Volney Landfill site, located in the Town of Volney, Oswego County, New York, is a 55-acre, unlined municipal landfill. From 1969 until 1983 municipal waste disposal operations occurred at the site. Most of the waste disposed of at the site consisted of typical residential, commercial, institutional and light industrial waste. However, between March 1974 and January 1975, Pollution Abatement Services, a hazardous waste incineration facility, was permitted to dispose of approximately 8,000 drums containing only residue coatings. Allegedly, 50 - 200 of these drums contained unidentified liquid waste. The condition of these alleged drums is unknown, as is their location within the landfill. In September 1983, waste disposal at the landfill ceased with the opening of the Bristol Hill Landfill approximately 2 miles southeast of the site. In the fall of 1985, closure operations for the Volney Landfill were completed by the current owner, Oswego County. Because the landfill is unlined and has a leachate collection system only in its newer (northern) section, leachate migration is occurring in both horizontal and vertical directions. The primary contaminants of concern affecting the ground water include: vinyl chloride, benzene, arsenic, VOCs and metals.
