SEPA United States Environmental Protection Agency EPA Region 8 Announces the Seventh Five-Year Review for the Libby Groundwater Superfund Site EPA, with the state of Montana, is conducting the seventh five-year review of the Libby Ground Water Contamination Superfund site (called the Libby Groundwater site or site) in Lincoln County, Montana. This review will ask if the remedies continue to protect human health and the environment and will come out in 2025. The previous 2020 five-year review is available on the site webpage. A lumber and plywood mill operated just outside of Libby in the late 40s through the late 60s. This resulted in contaminated soil and groundwater at the site. EPA divided the site into two sections called Operable Units. The Operable Unit 1 remedy includes components to reduce or eliminate human exposure to contaminated groundwater as an interim remedy. The last review showed the remedy for this area was short- term protective. However, to be protective long term, the review recommended additional controls to stop groundwater use outside city limits. The Operable Unit 2 remedy includes treatment of contaminated soil and groundwater and components to reduce human exposure to. The last review rated this area as short-term protective. To be protective long term, the review recommended additional remedial action and controls to make sure that people don't eat, inhale, or touch contaminated soil or drink contaminated water. We want to hear from you! Community members can share important information that helps EPA evaluate the remedies.
