Shane BradtU.S. Environmental Protection Agency Health Assessments for Cyanobacteria – an online presentation given on March 24, 2021 by Lesley D’Anglada of the U.S. Environmental Protection Agency.
Abstract
The U.S. Environmental Protection Agency (EPA) Office of Water is responsible for the development of non-regulatory Health Advisory for contaminants that can affect drinking water quality under the Safe Drinking Water Act (SDWA), and water quality criteria for the protection of public health in recreational waters under the Clean Water Act (CWA). In 2015, the EPA Office of Water conducted a comprehensive review of the toxicological and epidemiological data for the cyanobacterial toxins microcystins, cylindrospermopsin and anatoxin-a. These effects assessments, or Health Effects Support Documents, were considered by EPA in the development of Health Advisories and recreational water quality criteria for microcystins and cylidrospermopsin. A summary of the human health effects evaluation from exposure to cyanotoxins in drinking water and during recreating in toxin contaminated waters will be discussed, along with an overview of EPA’s approach to address HABs in freshwater systems.
