River pollution is a major environmental concern for the Mississippi River today.

River pollution poses a significant threat to the health of the Mississippi River, impacting water quality, aquatic life, and local communities. Sources of pollution include agricultural runoff, industrial discharges, and untreated sewage, which introduce harmful chemicals and nutrients into the water. This pollution can lead to issues such as algal blooms, fish kills, and contaminated drinking water. Addressing river pollution is crucial for preserving the river's ecosystem and ensuring safe water for millions of people.
