Superfund Site Profile


The 23-acre Hocomonco Pond site is located in Westborough, Massachusetts. The area is bordered on the northwest by Hocomonco Pond, a 27-acre freshwater pond long used for recreation. From 1928 to 1946, a wood-treating and preservation facility operated on site. Facility operations contaminated sediments, surface water and groundwater with creosote. Following construction of the site’s long-term remedy, operation and maintenance activities and monitoring are ongoing.


Institutional Controls are required for this site.

This site requires ICs because a decision document, such as a Record of Decision, has documented some level of contamination and/or remedy component at the site that would restrict use of the site. In order to determine the current status of ICs for 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.
