About the Superfund Redevelopment Initiative
This nationally coordinated effort provides EPA and its partners with a process to return Superfund sites to productive use. Learn more at Superfund Redevelopment Initiative.
Redevelopment at the Site
From 1966 to 1980, two companies manufactured plastic molding at the 15-acre Cheshire Ground Water Contamination Superfund site in Cheshire, Connecticut. Operations contaminated soil and groundwater with chemicals and solvents. In 1990, EPA placed the site on the Superfund program’s National Priorities List (NPL). Cheshire Associates, under state and EPA orders, cleaned up the site by removing some contaminated soil. EPA extended the public water supply to residents with drinking water wells affected by site contamination. Carten Controls, a subsidiary of Fujikin of America, Inc., relocated to the site in 1996. EPA took the site off the NPL in 1997. Carten Controls continues to manufacture parts at the site for the semiconductor industry.
Economic Activity at the Site
As of December 2019, EPA had data on one on-site business. This business employed 15 people and generated an estimated $3,800,000 in annual sales revenue. View additional information about redevelopment economics at Superfund sites.
Activity and Use Limitations
At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.
Institutional Controls are not required for this site.
This site does not require ICs which means there is no contamination remaining at the site that could result in an unacceptable exposure and/or remedy components at the site that could be damaged. For additional information on this site, the site contacts should be consulted.

ICs are generally defined as administrative and legal tools that do not involve construction or physically changing the site. Common examples of ICs include site use and excavation restrictions put in place through State and local authorities like zoning, permits and easements. ICs are normally used when waste is left onsite and when there is a limit to the activities that can safely take place at the site (i.e., the site cannot support unlimited use and unrestricted exposure) and/or when cleanup components of the remedy remains onsite (e.g., landfill caps, pumping equipment or pipelines). Effective ICs help ensure that these sites can be returned to safe and beneficial use.

In addition to the areas addressed by the institutional controls identified on this web site there may be other areas on the property that require restrictions on use of the property that are not captured in this EPA database. States and other entities may have implemented laws or restrictions applicable to this site.
