libby ground water contamination

1119 & 1415 DAKOTA

The Libby Ground Water Superfund site is located on the western edge of Libby, Montana. Approximately 11,000 people live in Libby and the surrounding areas. The site is bordered by Flower Creek, Libby Creek and the Kootenai River. The Libby Ground Water site is actually part of the Kootenai Industrial Park, which itself is an operable unit of the Libby Asbestos Superfund site. This site was part of a lumber and plywood mill and was used for treating wood with creosote, pentachlorophenol (commonly referred to as PCP), and other chemicals between 1946 and 1969. In 1979, contamination of well water with PCP at a nearby residence was first discovered. The site was added to the National Priorities List in 1983. Cleanup at the site began in 1986 and is ongoing.
