Beach Water Quality forecasts provide the best estimate of the chance a given location will observe concentrations of E. coli exceeding critical threshold values; thereby, affecting the quality of human health.

Individual Beach Forecasts are produced from combining antecedent conditions (winds, waves, currents, temperatures, river flow, etc)  that historically produce high concentrations of E. coli. 

This effort is an extension of the:

NOAA Center of Excellence for Great Lakes and Human Health at the NOAA Great Lakes Environmental Research Laboratory.
