EPA to review cleanups at eight New England Superfund sites this year

February 13, 2026

BOSTON (Feb.13, 2026) - U.S. Environmental Protection Agency (EPA) will conduct comprehensive reviews of completed cleanup work at eight National Priorities List (NPL) Superfund sites across New England this year.

Each individual site will undergo a legally required Five-Year Review to ensure that previous remediation efforts continue to protect public health and the environment. Upon completion of the Five-Year Review, the report will be available online on each site's individual Site Profile Page.

"As required by Superfund legislation, EPA is statutorily required to conduct comprehensive Five-Year Reviews on Superfund Sites across the New England Region," said EPA New England Regional Administrator Mark Sanborn. "Making sure the remedy is operating as intended is important to protecting stakeholders, communities, and the surrounding environment."

This year, EPA will conduct Five-Year Reviews for the sites listed below. The web links provided include detailed information on the status of each site, previous assessments and cleanup activities.

Five-Year Reviews of Superfund sites starting in 2026:

Callahan Mine (Brooksville, Maine)

Coakley Landfill (Greenland and North Hampton, New Hampshire)

Durham Meadows (Durham, Connecticut)

Eastern Surplus (Meddybemps, Maine)

Pine Street Canal (Burlington, Vermont)

Savage Municipal Water Supply (Milford, New Hampshire)

Five-Year Reviews of Federal Facilities starting in 2026:

Fort Devens Sudbury Training Annex (Hudson, Stowe, Maynard, and Sudbury, Massachusetts)

U.S. Army Materials Technology Laboratory (Watertown, Massachusetts)

Why this Matters:

Five-Year Reviews (FYRs) generally are required when hazardous substances remain on site above levels that permit unlimited use and unrestricted exposure. FYRs provide an opportunity to evaluate the implementation and performance of a remedy to determine whether it remains protective of human health and the environment. EPA retains responsibility for determining the protectiveness of the remedy.

More information:

The Superfund program, a federal program established by Congress in 1980, investigates and cleans up the most complex, uncontrolled, or abandoned hazardous waste sites in the country and EPA endeavors to facilitate activities to return them to productive use. In total, there are 123 Superfund sites across New England.
