The Barkhamsted-New Hartford Landfill site is located near the Barkhamsted-New Hartford town line in northwest Connecticut. The 98-acre area was an unlined landfill that leaked hazardous solvents and volatile organic compounds (VOCs) into the underlying groundwater. The landfill was capped in 1999. Groundwater is now being cleaned and monitored .
What Has Been Done to Clean Up the Site?
The site is being addressed through state and potentially responsible party (PRP) actions. The site’s next five-year review is scheduled to be completed by September 2018.
A third 5-year review, completed in September 2013, found the cleanup to be protective of human health and the environment. The review concluded remedial activities so far have adequately addressed all exposure pathways that could result in unacceptable risk. Exposures to contaminated groundwater from the site does not present a threat; the landfill cap continues to prevent direct contact with the waste; a long-term monitoring program is in place; and land use restrictions have been recorded.
What Is the Current Site Status?
EPA has conducted several five-year reviews of the site’s remedy. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended by site decision documents. The most recent review concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment in the short term. Exposure to contaminated groundwater from the site does not present a threat. The landfill cap continues to prevent direct contact with the waste. A long-term monitoring program is in place. Land use restrictions have been recorded.
For the remedy to be protective in the long term, the northeastern portion of the landfill perimeter fence must be repaired; animal burrows must be filled in and drainage features on the cap must be repaired; and analytical methods must be chosen to ensure laboratory reporting limits meet cleanup goals for groundwater and ecological benchmarks for surface water and sediment. In addition, an index analysis must be done on the sediment hazard to evaluate if objectives have been met; the continuing effectiveness of monitored natural attenuation processes must be verified and a revised time estimate for achieving goals must be met. Finally, drinking water samples from the new “Garage Well” must be included in the long-term monitoring plan.
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 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. These ICs are required to help ensure the site is used in an appropriate way and that activities at the site do not damage the cleanup components. These ICs will remain in place for as long as the contamination and/or cleanup components stay on site. The site contacts should be consulted if there are questions on the ICs for this site.
The following IC Instruments provide media-specific use restrictions that have been implemented by EPA for protecting human health, the environment and remedial engineering on this site. Instruments are documents used by EPA or other organizations to implement the use restrictions at a site. To know about other media-specific use restrictions that are planned but not implemented at this site, please contact the Regional Office using the Site Contact listed above

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.

Sampling and Monitoring
The landfill was capped in 1999. Groundwater is now being cleaned and monitored.
