What are cyanobacteria?
Source: The United States Environmental Protection Agency
Cyanobacteria, or blue-green algae, naturally occur in lakes, rivers and other freshwater systems. Cyanobacteria can rapidly form harmful algal blooms (HABs) in certain environmental conditions, including warm, slow-moving water with abundant nutrients. Some HABs are capable of producing cyanotoxins which can pose health risks to humans and animals through drinking water and recreational water exposure.
