Site Description
[Back to Top]

The Barkhamsted-New Hartford Landfill site encompasses 98 acres near the Barkhamsted and New Hartford town line. Since 1974, the site has been owned and operated by the Regional Refuse Disposal District One. The unlined landfill accepted municipal and industrial wastes, including oily metal grindings and sludge containing heavy metals. A barrel-crushing operation to reclaim metals was also located on site. In 1983, leaking drums containing hazardous solvents were observed on site during a State inspection. Tests indicated volatile organic compounds (VOCs) were present in shallow and deep wells on site. An unnamed brook borders the site to the southwest and the north and flows through a wetland to the Farmington River. The surrounding area is rural and residential. Many private wells and a municipal water supply well serving an estimated 4,800 people are located within 3 miles of the site. The site was closed under State solid waste regulations.

Threats and Contaminants
[Back to Top]

The groundwater underlying the site is contaminated with VOCs including xylene, toluene, and vinyl chloride, all of which are present in shallow and deep wells. The site is not completely fenced, making it possible for people and animals to come into contact with hazardous substances. Potential public health threats include accidentally ingesting or coming into direct contact with the groundwater or surface wastes. A wetland near the site could be threatened by contamination.

Cleanup Approach
[Back to Top]

The site is being addressed in two stages: initial actions and a long-term remedial phase focusing on cleanup of the entire site.

Response Action Status
[Back to Top]

Initial Action The Farmington Valley Health District shut down the on-site well serving the landfill office because of VOC contamination.

Entire Site An investigation into the nature and extent of site contamination began in the fall of 1991. The Remedial Investigation was completed in February 1996. Additionally, EPA issued an Action Memo for the source control remedy (i.e., landfill cap) in June 1996. EPA and the Connecticut Department of Environmental Protection also reached agreement in 1996 that enabled the landfill owner to design measures to contain and treat contamination. This was enforced by the State of Connecticut as a result of a Consent Order with potentially responsible parties which was signed in August 1996. Under the terms of the agreement, the landfill owner retained a consultant to design a protective cap for the landfill, a system to collect and treat runoff and contaminated leachate, and a system to capture landfill gases. The physical construction of the landfill cap was complete in the fall of 1999. EPA issued a Record of Decision (ROD) for the groundwater remedy in September 2001. The major components of the remedy are:
1. Remediation of groundwater to cleanup levels by natural attenuation, a naturally-occurring in-situ process that is expected to take approximately sixteen years before groundwater will meet applicable standards;

2. Installation of groundwater monitoring wells in the down-gradient part of the plume;

3. Institutional Controls to prevent ingestion and contact with contaminated groundwater. Institutional controls for this Site include environmental land use restrictions (ELURs) on present and future uses, and groundwater use restrictions;

4. A public education program involving informational meetings and/or mailings to discuss potential Site hazards;

5. Long Term Monitoring of groundwater, surface water, and sediment to evaluate changes over time and to evaluate the success of the remedial action; and

6. Five-year Review.

Institutional controls in the form of ELURs were implemented in the fall of 2003. A second five year review was also completed in September 2008, and concluded that the cleanup remains protective of public health and the environment.


Environmental Progress
[Back to Top]

The EPA has studied the conditions at the Barkhamsted-New Hartford Landfill site and determined that since the contaminated water source has been removed from service, no other initial actions are required while final cleanup actions are being implemented.

Current Site Status
[Back to Top]

This municipal and industrial landfill was listed in 1989. Cap construction began in 1998 and was completed in 1999. The Remedial Investigation/Feasibility Study (RI/FS) for groundwater was finalized during the summer of 2001. Sampling in 2000 provided the results necessary upon which to base a final remedy decision. A Record of Decision (ROD) and construction completion for the landfill cap were issued in September 2001. Installation of new monitoring wells was performed in 2003. The groundwater is currently being remediated through monitored natural attenuation.

During the Summer of 2005 it was discovered the gabian basket drainage downchutes were damaged which caused some erosion to occur. Drainage downchutes were repaired in October and November 2005. A five year review was completed in September 2008.
