The Marathon Battery Corp. site is located in Cold Spring, New York. The 70-acre area includes a now-demolished nickel-cadmium battery plant and 11 surrounding acres, the Hudson River in the vicinity of the Cold Spring pier, and a series of river backwater areas known as Foundry Cove and Constitution Marsh. The battery facility operated from 1952 to 1979, producing military and commercial batteries. Facility operations contaminated soil and groundwater with hazardous chemicals.
Following immediate actions to protect human health and the environment, the site�s long-term remedy was put in place. EPA took the site off the Superfund program�s National Priorities List in October 1996. The site is now ready for reuse. East Foundry Marsh and East Foundry Cove have been acquired by Scenic Hudson, a conservation organization.
