How States Have Responded to the EPA's Health Advisory Level for Cyanotoxins

In 2016, the second edition of our SDWA Newsletter discussed algal blooms and algal toxins. At that time, the U.S. Environmental Protection Agency established health advisories for two algal toxins, microcystin and cylindrospermopsin. The HAs had been in effect for about one year following several algal blooms that gained nationwide attention.
