Institutional controls are required for this site.
This site requires ICs because a decision document, such as a Record of Decision, has documented some level of contamination and/or remedy component at the site that would restrict use of the site. These ICs are required to help ensure the site is used in an appropriate way and that activities at the site do not damage the cleanup components. These ICs will remain in place for as long as the contamination and/or cleanup components stay on site.  The site contacts should be consulted if there are questions on the ICs for this site.

The 13-acre New Hampshire Plating Co. site is located in Merrimack, New Hampshire. An electroplating facility operated on site from 1962 to 1985. Wastewater containing metals, solvents and cyanide used in the electroplating operations was discharged into drainage channels in the former building floor, and flowed into unlined lagoons north of the building. Contaminants from the unlined lagoons affected on-site wetlands, contaminated surface and subsurface soils, and reached the groundwater. Following cleanup, operation and maintenance activities are ongoing.
