The treated effluent from East Prairie WWTP enters local waterways that flow into the Mississippi River, one of the largest river systems in North America. The Mississippi River supports a wide range of fish, birds, and other wildlife, and its water quality is critical for downstream communities and ecosystems. The plant's discharge contributes to the nutrient load in the river, which can affect algal growth and oxygen levels in the Gulf of Mexico.
