Harmful Algal Blooms

August 16, 2014
By Scott Shalaway (sshalaway@aol.com) , Post-Journal

During the first four days of August, the Western Basin of Lake Erie made national news. A harmful algal bloom (HAB) threatened the water supply near Toledo, Ohio. Wind and water currents pushed a bloom of blue-green algae (cyanobacteria) to the city's water plant intakes. Toxins (microcystin is of greatest concern) produced by this algal bloom made the water undrinkable for several days. Microcystin can cause skin rashes, intestinal problems, nervous system, liver and kidney damage, so it is essential that it be removed before water is deemed safe.
