Impairments under the Clean Water Act
Two impairments under the federal Clean Water Act continue to impact the Minneapolis segment of the Mississippi River.
The river throughout the length of Minneapolis remains impaired for E. Coli bacteria. Swimming or other contact with water impaired for E. Coli can make humans sick. The state is currently working on a plan to reduce E. Coli in this portion of the river.
Three contaminants from river water currently accumulate in the tissue of fish: mercury, PCBs, and PFOS. Because of this contamination, the Minnesota Department of Health recommends limiting the consumption of fish from this portion of the river. For healthy adults, that means just one meal a week for most fish, and in some cases even less. The recommendations for pregnant women and children are even more limited.
