Freshwater Science: Evaluating Interventions for Harmful Algal Blooms in Grand Lake St. Mary’s

January 25, 2023

Alum application is sometimes used to treat or prevent harmful algal blooms in inland lakes such as Ohio’s Grand Lake St. Mary’s, which experiences severe harmful algal blooms similar to Lake Erie’s western basin. But a 2021 Wright State University study suggests that the benefits, if any, of alum application and other interventions are short-lived.

Dr. Mark McCarthy, who led the project, suggests that climate change and external nitrogen inputs play a larger role in the persistence and severity of algal blooms in these lakes.

The webinar is free, but registration is required to receive log-in information.
