RT. 202
The South Municipal Water Supply Well Site (the Site) covers 250 acres in a rural portion of the Contoocook River Valley. The well was installed in 1952 and provided water to the Town of Peterborough for nearly 30 years. The well served approximately 4,600 people. In 1982, the State conducted a routine sampling of their water supply and found contaminants in the South Well, at which time it was shut down. The source of the contamination was thought to be the New Hampshire Ball Bearings (NHBB) facility, located 1,200 feet west of the well, which has manufactured precision ball bearings since 1946. In 1955, the company purchased the 24 acres it now occupies off of Route 202 in Peterborough. Major source areas on the property include discharges from three drainage outfalls, an inactive leachfield, and drainage from a tank truck used to haul waste from the facility. A brook located 200 feet from the facility drains into a wetland area and Noone Pond before emptying into the Contoocook River. Discharges to the leachfield and sump ceased in 1972 with connection to the town sewer line. Periodic on-site dumping of a 275-gallon tank truck containing waste solvents ceased in the late 1970s. Floor drains in the plant were sealed in 1983. The population of the Town of Peterborough is over 6,000. Less than 100 single-family residences are located within a 1-mile radius of the Site, and the nearest private residence is located approximately 1,000 feet from the NHBB facility.
