The goal of this project is to develop rapid-assessment tools that can identify cyanobacterial harmful algae bloom (cHAB) growth and toxicity in Minnesota lakes.

Why do this?

Cyanobacterial harmful algae blooms (cHABs) have been reported with increasing frequency in recent years and have now been documented in all five Great Lakes. Annual estimates of the economic costs associated with cHABs in the United States exceed $4 billion per year with single events in the Laurentian Great Lakes having estimated costs approaching $65-70 million.
