Toxic blooms of cyanobacteria have been forming on Lake Erie for several years now.
A kind of cyanobacteria called Microcystis produces a toxin that can hurt pets and make the water unsafe to drink. Back in 2014, Toledo had to shut down its drinking water supply because of the toxin.
The states around the lake – and Ontario - are working to cut back on phosphorus. It’s a nutrient that runs off from farms and wastewater treatment plants and makes those toxic blooms grow like crazy.
The Great Lakes Commission just launched a new pilot program with Michigan, Ohio, Indiana and Ontario. It’ll be a trading program for phosphorus, and they’re calling it the Erie P Market.
