EPA Completes Review of Linemaster Switch Corp. Superfund Site in Woodstock, Connecticut

John Senn (

WOODSTOCK, CONN. – EPA recently completed a comprehensive review of the site cleanup work previously completed at the Linemaster Switch Corp. Superfund Site in Woodstock, Conn. by performing a required Five-Year Review. 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.

"EPA performs Five-Year Review evaluations at Superfund Sites to ensure that our implemented site remedies continue to protect public health and the environment," said EPA New England Regional Administrator Dennis Deziel.

"It is important to ensure that remedies put in place to protect public health remain effective over time. The Department commends USEPA for continuing to evaluate this remedy and ensuring for the on-going safety of the citizens of Connecticut," said CT Department of Energy and Environmental Protection Commissioner Katie Dykes.

During 2019 EPA technical staff conducted a Five-Year Review of the Linemaster Switch Corp. site in Woodstock. The final report can be found on EPA's site profile page (see: in in the "Site Documents and Data" section.


Throughout the Superfund process of designing and constructing a cleanup remedy for a hazardous waste site, EPA's first goal is to make sure the remedy will be protective of public health and the environment. At many sites, EPA continues to ensure protectiveness by requiring reviews of completed cleanups every five years. It is important for EPA to regularly check on these sites to ensure the remedy is working properly. Five-year review evaluations identify potential issues and, if called for, recommend action(s) necessary to address them.

EPA is actively involved in Superfund studies and cleanups at 18 sites across Connecticut. There are many phases of the Superfund cleanup process including considering future use and redevelopment at sites and conducting post cleanup monitoring of sites. EPA must ensure the remedy is protective of public health and the environment and any redevelopment will uphold the protectiveness of the remedy into the future.
