Harmful Algal Blooms in Pennsylvania

Science Center Objects

The U.S. Geological Survey is collaborating with State and local partners to develop models that provide real-time estimates of Escherichia coli (E. coli) (for pathogens) and (or) microcystin (for freshwater cyanotoxins) levels at Great Lakes beaches and drinking-water intakes. 

Near real-time water quality conditions in Lake Erie are available during local beach season via Great Lakes NowCast.
