What is cyanobacteria?

Cyanobacteria are a type of algae commonly found in freshwater environments, including those used for drinking water. Some cyanobacteria produce potent toxins which can cause serious health issues.

To ensure drinking water is safe, water supplies that have some risk level must be monitored for the level of cyanobacteria and toxins present.
