The Issue

For too long, residents have witnessed what appears to be an ongoing discharge of untreated or inadequately treated sewage into a local stream in Leadwood, Missouri. This is not simply an inconvenience, it is a matter of public health, environmental protection, and government accountability. Raw sewage can contain harmful bacteria, viruses, parasites, and other contaminants that threaten people, wildlife, and downstream waterways. Missouri’s streams belong to all of us, and they deserve to be protected—not treated as disposal sites for untreated waste. Communities should never have to wonder whether the water flowing through their neighborhoods is contaminated because critical infrastructure has been allowed to deteriorate or because known problems have gone unresolved.

We recognize that aging infrastructure and unexpected equipment failures can happen. However, when sewage discharges continue over an extended period of time, residents deserve transparency, accountability, and a clear plan to permanently resolve the problem.

We are calling upon federal, state, and county leaders—including the U.S. Environmental Protection Agency, the Missouri Department of Natural Resources, the Governor of Missouri, our elected representatives, and local officials—to work together to ensure this matter receives the attention it deserves.

Specifically, we ask for:

     • An immediate investigation into the reported sewage discharge.
     • A comprehensive inspection of Leadwood’s wastewater collection and treatment system.
     • Public disclosure of the findings.
     • A permanent corrective action plan with measurable deadlines.
     • Appropriate enforcement if violations of environmental laws are identified.
     • Continued oversight until the problem has been fully resolved.

This petition is not about politics.

It is about protecting public health.

It is about preserving Missouri’s natural resources.

It is about ensuring that environmental laws are applied fairly and consistently, regardless of the size of the community involved.

Every Missourian deserves clean streams, clean water, and confidence that public officials will act when environmental concerns are brought to their attention.

If you believe our communities deserve safe waterways and responsible stewardship of our environment, please sign this petition and help us urge our leaders to take immediate action.

Together, our voices can make a difference.

I want to assure the residents of District 117 that the situation involving sewage and Big River is a priority for us, particularly as the issue appears to become more significant during periods of high water and flooding. One of our immediate concerns has been protecting public safety by making sure appropriate signage is in place to prevent public access to areas that may be affected. To that end we have been in contact with the Missouri Department of Natural Resources, the Department of Health and Senior Services, the Department of Conservation, and local city officials to request testing, repair, and signage warning of public health concerns. We are also reaching out to state and national departments with requests for grant funding to assist the Leadwood community with repair or replacement costs. DNR has reported that they are actively working the area with testing and meetings with City officials and other departments to put together a repair plan. My understanding is that they will be releasing a public statement and posting public health warning signs this week. We understand the concern this situation has caused, and we will continue working with the appropriate agencies and local officials to advocate for the health, safety, and well-being of our community. Thank you for bringing your concerns forward.

FOR IMMEDIATE RELEASE: Leadwood wastewater facility makes progress toward repairing failing system: MoDNR E. coli levels still high in Big River near facility JEFFERSON CITY, MO, AUG. 14, 2026 – According to the Missouri Department of Natural Resources, Leadwood’s wastewater facility is beginning to make progress toward repairing its failing treatment system. Recent sampling in the Big River upstream, at the facility’s outfall and downstream, show E. coli levels are slightly improving. However, those levels are still high, indicating the facility is still unable to effectively treat the city’s wastewater. On Aug. 10, MoDNR continued its water sampling schedule in the Big River. Preliminary results from samples collected at the facility’s outfall show E. coli levels at 1,732.9 colony forming units per 100 milliliters (CFU/100mL), down from >2,419.6. Sample results from other locations show E. coli at the time was 150.0 CFU/100mL at the Mounts Big River Access, 73.8 CFU/100mL at the Hunt Street Leadwood Access and 80.1 CFU/100mL at the Bone Hole Swimming Basin. Until the treatment plant’s capacity improves and starts attaining permitted effluent limits, people should heed the public health advisory signs posted at access points on the Big River from the Leadwood Access to Owl Creek Park in St. Francois County. The signs advise people to avoid water contact (swimming, wading, etc.) and to keep pets and livestock away from the water in that section of the Big River. The department emphasizes that E. coli levels in natural water bodies can fluctuate dramatically over time, typically increasing after it has rained and decreasing when the weather is dry. Because of this phenomenon, people should always be careful when playing in and around lakes and streams. In a concerted effort to address the facility’s failing treatment equipment, the city is installing a replacement pump to move sludge and solids from the plant’s clarifier to the sludge holding basin. Adding the new pump is designed to allow the plant to begin treating the wastewater more efficiently, which should help further reduce E. coli levels in the treated water the plant releases to the Big River. The city is also considering additional treatment options to further improve plant operations. To find more permanent solutions, the department’s Financial Assistance Center is working with the city to help identify emergency funds through the Department of Economic Development’s Community Development Block Grant along with funds from the department for immediate repairs. The department is also working with the city on funding opportunities for long-term system upgrades with grants and loans to ultimately build a new treatment facility. In the meantime, the department continues to make weekly site visits to monitor progress and to collect water quality samples. “The department continues to work with the city and other partners to find both short-term and long-term solutions to Leadwood’s wastewater treatment challenges, said Kurt Schaefer, director of the Department of Natural Resources. “We anticipate seeing improvements in the facility’s operations, reflected in better sampling results in the Big River. This issue has developed over time, so it will take time to find and implement lasting solutions.” For background about this issue, see the previous department news release at: https://dnr.mo.gov/communications/news/department-natural-resources-takes-action-address-failing-leadwood-wastewater-treatment-facility.
