Protecting The Elm Point Wellfield

On September 29, 2022, the U.S. Department of Justice lodged a Consent Decree between the United States, the State of Missouri, and Ameren Missouri with the federal court in St. Louis. On October 4, 2022, the Consent Decree was made available for public comment for a period of 30 days. The Consent Decree provides the legal basis defining Ameren Missouri’s responsibilities for cleaning up its portion of contamination in the Elm Point Wellfield. The Consent Decree is largely based on information and data generated as part of the June 2021 Record of Decision issued by the USEPA prior to the identification of hazardous chemicals in the City drinking water wells CW-6 and CW-8 over the past year.

It is critical that Ameren Missouri and the other parties responsible for contamination in the Elm Point Wellfield are held responsible by the USEPA and Missouri DNR. Therefore, the City of St. Charles has requested immediate action be taken including:

3. The USEPA should require Ameren Missouri and other responsible parties to immediately design and install upgrades to the City’s drinking water treatment plant to remove the hazardous chemicals to ensure continued safety of the public drinking water
