MILL ST-RTE 113

Precision stainless steel castings were manufactured by the Kearsarge Metallurgical Corporation (KMC) from 1964 until the company went out of business in 1982. The area surrounding the KMC Site is industrial and, following more than 20-years of remedial actions, a new owner now operates a number of businesses at the 9-acre Site. The original contamination resulted from liquid and solid wastes produced from the cast-making processes that were disposed of on site during the 1970's and early 1980's. A large, 20-foot-high pile of approximately 9,000 cubic yards of solid waste was located behind a foundry building and surrounded by a chain link fence. This waste pile contained ceramic sand, scrap metal, rusted drums, and various other refuse from foundry operations, and extended across the Kearsarge property line. The remedial action at the Site removed all surface contamination and more than 99% of the groundwater contamination. Contaminated groundwater remains in one isolated area on the eastern edge of the Site. Two municipal wells are located approximately 3,000 feet north of the site and supply most of the drinking water to the Town of Conway. Pequawket Pond marks the southern boundary of the site and is used for recreational purposes. Approximately 8,100 people live within 3 miles of the site, and 2,700 people within 3 miles of the site use groundwater in the area for drinking purposes.
