Harmful Algal Blooms and Cyanotoxin Health Advisories: An EPA Public Meeting and Webinar
(NEW YORK, NY – May 7, 2015) – The Environmental Protection Agency (EPA) is hosting a day-long stakeholder meeting on Monday, May 11 in Arlington (VA) to discuss harmful algal blooms and their intent to issue Cyanotoxin Health Advisories.
Cyanobacteria are naturally occurring organisms similar to algae. These organisms can occur in fresh water and may rapidly multiply causing “blooms” under favorable conditions. Conditions that enhance bloom formation and persistence include light intensity and duration, nutrient availability (such as nitrogen and phosphorus), water temperature, pH and water column stability. Some blooms produce cyanotoxins such as microcystin, cylindrospermopsin and anatoxin-a, which can be a health concern.
The EPA is developing health advisories for two cyanotoxins: microcystin and cylindrospermopsin. A health advisory is an estimate of acceptable drinking water levels for a contaminant based on health effects and other information, and also provides recommended analytical and treatment techniques. Health advisories are intended to assist federal, state, and local officials and public water system managers in achieving public health goals.
The focus of this public meeting is to gather input on additional information the Agency can provide to states and public water systems to help them prepare for and respond to potential cyanotoxin health concerns in drinking water.
