Harmful algal blooms and their associated toxins pose a risk to drinking water quality. EPA has released a comprehensive strategic plan outlining actions to address algal toxins in drinking water. Solving the challenge of algal toxins in drinking water will require action at all levels of government and approaches that are collaborative, innovative, and persistent. EPA will work closely with other federal agencies, state and local governments, and the public to provide scientific and technical leadership on a number of fronts, including health effects studies. The agency will work on treatment techniques and monitoring technologies, develop innovative mapping tools to help protect drinking water sources, provide technical support to states and public water systems, issue health advisories, and support activities to protect drinking water sources.
