Mohawk Tannery is a federal Superfund site in New Hampshire. The Superfund program, created by Congress in 1980, addresses sites where hazardous substances have been released or threaten release into the environment. EPA scores potential sites using the Hazard Ranking System; those that score high enough are placed on the National Priorities List.
Current status: Proposed for NPL. This site has been proposed for the National Priorities List but is not yet formally listed. Proposal triggers a public comment period. If listed, EPA conducts a remedial investigation to characterize contamination before selecting a cleanup approach.
Contamination has been detected in soil.
If you live near this site and have health concerns, your state health department can provide site-specific guidance. EPA maintains a community involvement program for most NPL sites, and site documents — including the Record of Decision, five-year reviews, and public health assessments — are typically available through EPA's Superfund site profile.
