Global Solutions to Regional Problems
Collecting Global Expertise to Address the Problem of Harmful Algal Blooms Workshop at Bowling Green State University
April 13-14, 2015
Harmful algal blooms are not unique to Lake Erie – they are global phenomena that affect millions of people across the world.
The goal of this NSF- and NOAA-sponsored workshop was to discuss the current science on bloom formers and factors contributing to CHABs, along with identifying knowledge gaps regarding bloom prevention and remediation. Additionally, discussion of case studies on current and prior remediation programs helped guide the development of a workshop paper that presents potential future strategies for bloom prevention, mitigation and long-term research goals.
- Biology of bloom-forming species
- Environmental factors underlying CHABs
- Sensor development in bloom detection
- Remote sensing
- Prediction of CHABs
- Best practices for control and remediation

In August 2014, the municipality of Toledo issued a “do not drink” advisory on their water supply that directly affected over 500,000 residents throughout the region. This state of emergency arose from the presence of high levels of microcystin in the city’s water supply. The microcystin was produced by a large bloom of cyanobacteria (CHAB: cyanobacterial harmful algal bloom) that was localized near the city’s water intake in Lake Erie.
