MPCA predicting blue-green algae blooms this summer

The Minnesota Pollution Control Agency is predicting new algae blooms for the 4th of July weekend.

Nutrients in run-off from spring rainstorms combined with persistent hot weather can trigger algae blooms that are harmful to people and pets.

Water that looks green and slimy, especially with a blue-green tint, should be avoided. M

ultiple reports of dog deaths have been attributed to toxic algae in recent years.

Toxic blue-green algae can affect people with skin, throat, eye and nose irritation, as well as nausea.

Blue-green algae isn’t actually an alga at all, it is a cyanobacterium that thrives in warm, nutrient-rich waters.

Phosphorous, the MPCA’s top pollutant of concern in the state’s lakes, fuels the growth of algae, and preventing phosphorus pollution is even more important in lakes warming as a result of climate change.
