The city of Eldon is under a boil water order effective immediately. This is the result of water samples testing positive for E. coli bacteria, indicating a potential acure health risk.
A routine water sample collected Tuesday, Dec. 16, from the Eldon distribution system tested positive for total coliform and E. coli. As required under the Revised Total Coliform Rule and Ground Water Rule, repeat samples were collected at and near the original sampling location and from source water nearest to the well. One of the repeat samples in a separate location collected Wednesday, Dec. 17 also tested positive for total coliform bacteria. The original violation location did NOT test positive.
As a result, the Eldon Public Water System has exceeded the E. coli Maximum Contaminant Level for December 2025, in violation of Missouri Safe Drinking Water Regulation 10 CSR 60-4.022 (10)(A). This violation has triggered a Level 2 Assessment and resulted in the issuance of Notice of Violation CFO26007.
Under authority granted by Section 640.130 RSMo, MDNR issued the Boil Water Order effective Dec. 18.
