Wyandotte - North Works
BASF moves forward with long-term environmental remedies at its Wyandotte North Works Site in a way that is protective of people and the environment.
BASF is working under the oversight of the U.S. Environmental Protection Agency (EPA) and the Michigan Department of Environment, Great Lakes, and Energy (EGLE) at the Wyandotte North Works Site, on various projects to address groundwater from the long-term and historical industrial activities at the North Works Site (Site). BASF is on schedule with the regulators to implement these measures at the Site.
This website is intended to provide you with updates, and we invite you to check back here regularly for the latest information.
There are four environmental projects being conducted:
- Groundwater Extraction System designed to control groundwater
- Perimeter Barrier Project designed to contain impacted groundwater to the Site
- Perimeter Resin Pilot Test Groundwater Collection System to treat PFAS in groundwater from historic joint firefighting exercises at the Site with the City of Wyandotte
- Sediment removal project to dredge sediments from the Upper Trenton Channel of the Detroit River
Groundwater Extraction System
BASF continues to operate a groundwater extraction system installed at the North Works site under a Consent Decree with EGLE. BASF continues to meet its obligations under the Consent Decree and is working with EGLE on modifications to the system.
Perimeter Barrier Project
EPA and BASF continue to finalize the Perimeter Barrier Project, a comprehensive, long-term groundwater protection measure, which includes constructing a physical barrier/wall along the north, east, and south property boundary of the North Works site.
In accordance with the regulatory process, this project required 30%, 60%, 95%, and final design submittals. On May 19, 2026, BASF submitted the final 100% design, completing the design phase of the overall project.
BASF received approval from the EPA for the 100% Basis of Design for the Permiter Barrier Wall on June 29, 2026. This marks an important milestone as the approval enables advancement of long-term solutions to address groundwater impacts from historical industrial operations, including those of prior owners at the Wyandotte North Works site.
The final design builds upon earlier phases and reflects a detailed engineering approach developed in coordination with regulators, including the EPA and EGLE. The project is expected to be completed in 2029.
Perimeter Resin Pilot Test Groundwater Collection System
In 2023, BASF received approval to operate a Perimeter Resin Pilot Test groundwater collection system to address PFAS in groundwater from historic joint firefighting exercises with the City of Wyandotte. The new system began operating in July 2023 and will be operated until construction of the Perimeter Barrier Project is completed. A larger treatment system is included in the Perimeter Barrier Project which will replace this Pilot Test system.
Questions regarding the City of Wyandotte's drinking water should be directed to the City. Information on the City's water, including quality, monitoring, and public reporting, can be found at Public Notice Regarding Drinking Water - Wyandotte, MI.
Upper Trenton Channel Sediment Removal Project
BASF, Arkema, and Union Carbide are working with the U.S. EPA's Great Lakes National Program Office to remove over 200,000 cubic years of sediment from a 3.25-mile stretch of the Upper Trenton Channel. This area includes legacy impacts which the EPA believes relates to multiple historic industrial activities.
