Missouri Waterways: 85% Fecal Contamination Alert

A comprehensive analysis has detected potentially unsafe levels of fecal contamination in 85 percent of Missouri's monitored recreational waterways. The report highlights that 171 out of 202 monitoring locations across the state's rivers, streams, and lakes registered such contamination on at least one day during 2024 and 2025. This widespread issue raises serious concerns for public health.

Exposure to fecal bacteria in water can lead to a range of ailments, including skin, eye, ear, and sinus infections, as well as gastrointestinal and respiratory illnesses. Specific areas like the Harry S. Truman Reservoir, Grand Glaize Creek, and Sycamore Creek were identified as having persistent bacterial risks.

The Environment America Research & Policy Center identified several sources contributing to the pollution, such as stormwater runoff, sewage overflows, livestock manure, and failing septic systems. For instance, parts of Big River recently showed high E.coli levels linked to the "failing" Leadwood wastewater treatment facility, which is undergoing temporary repairs.

Addressing these contamination issues requires substantial investment in infrastructure upgrades, including replacing sewer lines and upgrading wastewater treatment plants. Missourians can seek assistance through the Clean Water State Revolving Fund. Nationally, the EPA estimated a need for approximately $630 billion over 20 years for water infrastructure improvements.
