In 2018, MPCA selected a remedy for the remaining soil contamination at OU5. Cleanup activities at OU5 began in late fall 2022 and will continue through mid-2023. The remediation plan includes excavation of contaminated soils and transportation to a permitted landfill. Remaining soils will be consolidated on-site and covered with a clean cap.

Joslyn Manufacturing Supply Co is a federal Superfund site in Minnesota. 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: Construction complete. Physical construction of the cleanup remedy is complete, though long-term monitoring and institutional controls typically continue for years or decades. Groundwater treatment systems, for example, often run long after surface cleanup finishes.
Contaminants of concern include chlorinated dioxins and furans, pentachlorophenol, polycyclic aromatic hydrocarbons (pahs). Contamination has been detected in soil, sediment, surface water, groundwater.
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.
