Superfund Site Profile
The Mercury Refining, Inc. site is located on the border of the towns of Guilderland and Colonie, New York. From 1955 to 1998, Mercury Refining Company, Inc. (MERECO) used the half-acre area for reclaiming mercury from batteries and other mercury-bearing materials. Facility operations contaminated soils, groundwater and sediments in a tributary of Patroon Creek with polychlorinated biphenyls (PCBs) and mercury.
Cleanup at the site was completed in 2014. Long-term groundwater and ecological monitoring is ongoing.
