The Troy Mills Landfill Site is located in Troy, Cheshire County, New Hampshire, along an unpaved, gravel access road originating from Rockwood Pond Road in Fitzwilliam, Cheshire County, New Hampshire. The site is within an approximately 10 acre inactive landfill. It consists of an estimated 2 acre area where approximately 6,000 to 10,000 55-gallon drums are buried alongside an estimated 8 acre inactive solid waste landfill. From 1967 until 1978, Troy Mills, Inc. used the 2 acre area to dispose of solid and liquid wastes generated at its facility located in the town of Troy, New Hampshire. Drummed wastes consisted primarily of plasticizers including bis (2-ethylhexyl) phthalate (DEHP) and Varsol, a petroleum-based solvent, also known as mineral spirits or Stoddard Solvent.
The site occupies the southeastern corner of a 270 acre land parcel identified by the town of Troy Tax Assessor as Lot No. 25 on Map Nos. 16 and 17. It is located in an area of mostly undeveloped woodlands. Other than the woodlands, it is bordered to the north by an intermittent stream; to the east by a former railroad bed currently utilized as a trail for walking, all terrain vehicles, and snowmobiles; to the west by the gravel access road, a wetland area, and Rockwood Brook; and to the south by the eastern branch of Rockwood Brook.
An estimated 3,886 people reside within 4 radial miles of the site. Approximately, 3,111 are served by public or private drinking water supply wells. The nearest private drinking water supply well is within 0.5 mile of the site. The nearest public drinking water supply well is located 2.8 miles southeast of the site. Sensitive environments located within 4 miles include 2,173 acres of wetlands, a CWA-protected water body, and habitats for eight State-listed endangered or threatened species.
Current Site Status and Cleanup Actions to Date
- Contaminated water flows from the surface of the landfill and as groundwater beneath the buried drum area. Previous inspections of the area have found landfill leachate stained sediment in Rockwood Brook along the wetland area near the site.
- In order to minimize the discharge of contaminated leachate, a Time Critical Removal Action was completed in late 2003, which resulted in the construction of an interceptor trench system to collect contaminants prior to their release to the wetland area.
- A second Time Critical Removal Action to remove drums from the landfill began in the July of 2004. Approximately 4,000 drums have been removed from the site as of the beginning of October 2004.
- A Remedial Investigation/Feasibility Study (RI/FS) was initiated in July of 2004 in order to determine what if any additional remedial actions will be necessary after the drum removal is complete.
Current Funding Status
- The Region has received nearly $9,000,000 for the two Removal Actions.
- $500,000 to begin the RI/FS was received in FY 04 and an additional $500,000 has been requested for FY 05.
