Superfund Site: MOHAWK TANNERY

Superfund Site Profile


The former Mohawk Tannery facility (a.k.a. Granite State Leathers) is located on approximately 30 acres in Nashua, Hillsborough County, New Hampshire. The currently inactive facility produced tanned hides for leather between 1924 and 1984. The site was proposed to the National Priorities List (NPL) on the basis of past disposal practices which included the direct discharge of wastewater containing such hazardous substances as chromium, zinc, and phenol into the Nashua River and the disposal of sludge containing such hazardous substances as chromium, pentachlorophenol, phenol, and 2,4,6-trichloropehenol into a number of unlined disposal areas at the site. Two of the largest disposal areas are located directly next to the Nashua River; with one of these areas within the 100-year flood plain. These disposal areas were not designed, constructed, operated, and maintained to prevent the washout of hazardous substances in the event of a flood. The confluence of the Nashua and the Merrimack Rivers is located approximately 3.5 miles downstream of the site. Both the Nashua River and the Merrimack River are fished extensively and wetlands are located along both rivers. Approximately 5,025 people receive drinking water from ground water wells within a 4-mile radius of the Site. However, a majority of the people living near the site are being supplied with potable water through the local water district.

The Site is comprised by two contiguous, approximately 15 acre parcels of land: a developed "northern parcel" that was historically used for tannery and waste disposal operations, and a "southern parcel" that is undeveloped and does not appear to have been used by the former tannery.
