Algal blooms, the slimy green substance on lakes and ponds, have a lot of people talking and asking questions. In particular, the algal blooms found in western Lake Erie were described as a cause for concern in a New York Times article written by Jugal K. Patel and Yuliya Parshina-Kottas that was published in October 3, 2017.

Why the concern? This particular bloom near Toledo, Ohio, covers 700 square miles and could be a harmful algal bloom (HAB). The bloom covers an area that supplies the drinking water to sources for about 3 million people. If this indeed is an HAB, there are a lot of human beings who could have HAB toxins in their drinking water source.

According to the EPA, 59% of blooms tested throughout the world have been deemed toxic.
