EPA Fulfills Statutory Obligation, Completes Reviews at Three Connecticut Superfund Sites
BOSTON (November 19, 2025) – U.S. Environmental Protection Agency (EPA) has fulfilled its statutory obligation and completed required comprehensive site cleanup reviews, known as "five-year reviews," for three Superfund sites on the National Priorities List across Connecticut during the 2025 Fiscal Year.
As required by law, every five years EPA conducts reviews at Superfund sites following the implementation of a cleanup. This comprehensive review of previous work helps ensure that EPA continues to evaluate the performance of cleanup efforts and determines whether any further action to protect human health and the environment is required.
The five-year review for each of the sites, are available on EPA's website. These reviews concluded that the remedies continue to be effectively in protecting human health and the environment and made recommendations for follow up actions where needed.
Completed Connecticut Five Year Reviews in Fiscal Year 2025:
Old Southington Landfill, Southington, Connecticut
Raymark Industries, Inc., Stratford, Connecticut
Solvents Recovery Service of New England, Southington, Connecticut
Background
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 endeavors to facilitate activities to return them to productive use. There are many phases of the Superfund cleanup process including considering future use and redevelopment at sites and conducting post cleanup monitoring of sites.
Throughout the process of designing and constructing a cleanup at a hazardous waste site, EPA's primary goal is to protect human health and the environment, the agency's core mission. EPA is required by statue to review the sites every five years after the cleanup is in place. It is important for EPA to regularly check to ensure the cleanup is working properly. These reviews identify issues (if any) that may affect the protectiveness of the cleanup and, if necessary, recommend action(s) to address them.
