Cyanobacterial Blooms and Cyanotoxins: Monitoring, Control, and Communication Strategies
Cyanobacterial blooms (also referred to as harmful algal blooms) can result in the release of cyanotoxins (or algal toxins). Several studies have investigated the toxicity of cyanotoxins and documented their human health effects, including gastroenteritis, liver damage, liver cancer, and neurotoxic effects.
In 2015, the EPA issued Health Advisories for states and utilities for two types of cyanotoxins: microcystins and cylindrospermopsin.
In 2016, WRF funded this Research Area to develop tools to help utilities prepare for cyanobacterial blooms, set practical monitoring methodologies, find cost-effective control strategies, build effective communication resources, and optimize watershed and source water management strategies.
Research Area Objectives
- Provide optimized watershed and source water management strategies.
- Investigate cost–effective control options.
- Offer practical guidance for control and treatment.
- Deliver public outreach and communication strategies and tools.
