U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin visited several Michigan environmental and infrastructure projects Sept. 25-27, including a PFAS research center and a large-scale contaminated sediment cleanup along the Kalamazoo River.

Zeldin toured the Michigan State University Center for PFAS Research with U.S. Rep. Tom Barrett, where he received an overview of research into PFAS. The EPA said it has provided more than $200 million to Michigan communities since 2025 to address PFAS.

EPA research on PFAS in water includes analytical methods for measuring PFAS occurrence, drinking water and wastewater treatment approaches, residual-stream management and methods for identifying contamination sources.

Zeldin also visited the Trowbridge Dam area, part of the Kalamazoo River Superfund Site, where EPA is overseeing dredging of PCB-contaminated sediment. The cleanup began in 2025 and has removed more than 300,000 cubic yards of contaminated sediment, according to EPA.

EPA said the project has also involved treating hundreds of millions of gallons of water generated during sediment processing before discharge back to the river. The agency expects dredging to be completed in 2026, followed by removal of the Trowbridge Dam and riverbank restoration.

The Michigan tour also included a visit to the Enbridge Stockbridge Terminal to discuss energy infrastructure and a tour of the Ford House, where EPA's Great Lakes Restoration Initiative has supported restoration work.
