2. A Better Way: An Application For Risk Characterization of HABs On The Ohio River 8/2/2022

   When you think of water, you might imagine deep blue ocean waves crashing against a shoreline or perhaps the still calm of a forested lake, but on an August morning in the summer of 2015, the lockmaster at the Pike Island Lock and Dam saw something much different. That day, EPA’s regional office in Wheeling, WV, received a concerned phone call from the Ohio River Valley Water Sanitation Commission (ORSANCO) notifying them of what was described as “antifreeze-green colored paint” flowing down the Ohio River. But this was no paint spill. Rather, Microcystis, a naturally occurring species of cyanobacteria, or blue-green algae, known to produce toxins harmful to animals and humans, was quickly taking over one of the most influential rivers in the continental U.S.
