Blue-Green Algae

What are cyanobacteria or blue-green algae?

Blue-Green Algae/Cyanobacteria are aquatic organisms that are found as floating mats on the surface of lakes or ponds. There are health concerns associated with contact Blue Green Algae and the toxins produced by some species. 

Does the presence of an algae bloom always mean the water is contaminated?

No. Just as not all cyanobacteria have blooms that are visible, not all cyanobacteria produce harmful toxins. Between 30 and 50 percent of blooms are from non-toxic species of cyanobacteria.
