Toxic algae can form a scum layer that looks like green pea soup. It can also look streaky, be dispersed in the water column or form clumps. 

Ingesting water contaminated with blue-green algae can cause muscle weakness, vomiting, diarrhea and nausea. Physical exposure to it can cause irritation or a rash.
