The executive director of the Iowa Regents’ Lakeside Lab says they’re seeing an increase in toxic blue-green algae in the Great Lakes. Mary Skopec says after years of drought, the lakes are filled with high levels of nitrogen, phosphorus, and contaminated sediment. It’s a combination that causes the algae to grow, especially when things warm up.
There are more than 70 places, where the shorelines have also collapsed, compounding the problem. Skopec says people can still swim in the Iowa Great Lakes but need to watch out for debris and stay away from water that looks green and murky and occasionally bright blue.
Skopec says the good news is E. coli testing in almost a dozen spots around the Great Lakes showed levels meeting recreation standards.
