ringwood mines/landfill


Magnetite mines were operated on the 500-acre Ringwood Mines/Landfill Site (Site) as early as the 1700s, and wastes have been disposed of at the Site since the 1960s. The Site is about 1/2 mile wide and 1 1/2 miles long and consists of rugged forested areas, open areas overgrown with vegetation, abandoned mine shafts and surface pits, an inactive landfill, an industrial refuse disposal area, small surficial dumps, a municipal recycling center, the Ringwood Borough garage, and about 50 private homes. Two abandoned mines, Peter's Mine and Cannon Mine, have been used for the disposal of garbage and other wastes over the years. Peter's Mine also contains paint sludges, solvents, and scrap metal. Several drums have been observed in Cannon Mine. Mining ended at the Site in the early 1900s, and the history of the Site is unclear from then until the late 1930s. The Site was purchased by the U.S. Government prior to 1940 and later was sold to a succession of owners. From 1965 until 1974, the Site was owned by Ringwood Realty, a subsidiary of the Ford Motor Company. During this period, Ford Motor Company wastes, including car parts and paint sludges, were disposed of on the ground surface and in abandoned mine pits. In 1970, Ringwood Realty donated 290 acres in the southern portion of the Site to the Ringwood Solid Waste Management Authority, which began operating a permitted municipal disposal area in 1972. The landfill was closed by the State in 1976. Ground water beneath the Site discharges to surface streams and the Wanaque Reservoir, located 1/2 mile southeast of the nearest on-site sludge disposal areas. The area around the Site is primarily residential, with about 50 residences located on or near disposal areas. The approximately 50 residences in the immediate vicinity of the Site receive water from a municipal water supply. Approximately 13,000 people live in Ringwood Borough. The Wanaque Reservoir provides drinking water to about 2,000,000 people Site Responsibility: This Site is being addressed through Federal and potentially responsible parties' actions.
