Superfund Site: NORTH RIDGE ESTATES, KLAMATH FALLS, OR
Superfund Site Profile
The North Ridge Estates Superfund Site is a residential subdivision located approximately three miles north of Klamath Falls, Oregon. The site is contaminated with asbestos as a result of the improper demolition of approximately eighty 1940s-era military barracks buildings. North Ridge Estates was added to the National Priorities List in 2011 after annual efforts to remove contamination were not effective for long-term protection of human health.
Asbestos-containing materials and soil will be removed from the old military barracks site during three seasons of cleanup. Additional contamination at the nearby Kingsley Firing Range, also part of the site, will be investigated and completed at a later time.
Clean Up Update:
The remedial construction for Season 1 began in late-July and will conclude at the end of November 2016 as heavy work is unable to be conducted during winter months. Construction staff will remain onsite through the winter months preparing for Season 2. Approximately 2 - 4 feet of asbestos contaminated soil and debris will be excavated and replaced with clean topsoil. The contaminated soil and debris will be placed in secure on-site repositories.
