The U.S. Environmental Protection Agency (EPA) has announced plans to conduct thorough reviews of the completed cleanup efforts at three Superfund sites in New Hampshire this year. Each site will be subjected to a Five-Year Review, a legal requirement aimed at ensuring that past remediation actions continue to safeguard public health and the environment.

The EPA will publish the findings from these reviews on each site's individual EPA profile once they are complete. The specific sites undergoing review include New Hampshire Plating Co in Merrimack, Somersworth Sanitary Landfill in Somersworth, and Troy Mills Landfill in Troy.

The Superfund program was established by Congress in 1980 with the goal of investigating and cleaning up hazardous waste sites that are complex, uncontrolled, or abandoned. The program also aims to return these sites to productive use. In New England alone, there are 123 Superfund sites under this federal initiative.
