Background

Magna Metals conducted metal plating, polishing, and lacquering operations at the site from 1955 to 1979. During operations, iron, lead, copper, nickel, zinc chlorides, cyanides, and sulfates were discharged to a series of leaching pits. As a result, the soil, groundwater, a nearby stream and sediment are contaminated with metals and volatile organic compounds.

The former Magna Metals plant was demolished in 2013. Buildings on the property are currently being used for offices, a laboratory, and warehousing. Some of the homes in the surrounding area, which is primarily residential, have contaminated soil on their property immediately adjacent to the brook, and are located near contaminated sediment. Affected residents have been provided with soil sample results and advised on how to reduce potential exposures in the short-term. Furnace Brook is the main surface water body that contains contaminated sediment, including approximately 1.5 miles of freshwater wetland.

The state of New York investigated the contamination, collected samples and conducted studies, which resulted in immediate steps to mitigate risks from potential exposure. Those steps included demolishing the former plant and installing a system to vent gas away from the occupied office and warehouse building at the facility. The New York State Department of Environmental Conservation supports inclusion of the site to the Superfund list.
