EPA Begins Review of Four Superfund Cleanups in the Nation’s Heartland
LENEXA, KAN. (MAY 4, 2026) – Today, the U.S. Environmental Protection Agency (EPA) announced it will conduct comprehensive reviews of cleanup work at four Superfund sites beginning this spring.
Each individual site will undergo a Five-Year Review to ensure ongoing or completed remediation efforts continue to protect human health and the environment. Upon completion of the review, EPA will make a Five-Year Review Report available on the Superfund Site Profile page.
“EPA Region 7 is committed to upholding the statutory requirements granted to it by Congress and will conduct comprehensive Five-Year Reviews at our Superfund sites across the Heartland,” said EPA Region 7 Administrator Jim Macy. “Protecting human health and the environment is our core mission, and we do that at Superfund sites by making sure remedies are operating as designed.”
This spring, EPA Region 7 will begin Five-Year Reviews for sites listed below:
- Vienna Wells in Vienna, Missouri
- E.I. DuPont de Nemours & Company Inc. County Road X23 in West Point, Iowa
- Mississippi River Pool #15 in Riverdale, Iowa
- Aluminum Company of America - Davenport in Riverdale, Iowa
Additional Five-Year Reviews in the Heartland are scheduled to start later this year and will be announced closer to the start date.
Why this Matters:
Five-Year Reviews generally are required when hazardous substances remain on-site above levels that permit unlimited use and unrestricted exposure. The reviews provide an opportunity to evaluate the implementation and performance of a remedy to determine whether it remains protective of human health and the environment. EPA retains responsibility for determining the protectiveness of the remedy.
More information:
The Superfund program, a federal program established by Congress in 1980, investigates and cleans up complex, uncontrolled, or abandoned hazardous waste sites in the country. EPA endeavors to facilitate activities to return them to productive use.
