Summary

Problem – Currently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for swimming on the basis of the previous day’s E. coli concentration. Sanitary conditions may change overnight and even throughout the day (Boehm and others, 2002) making decisions made from previous days information incorrect. Because of this time-lag issue, water-resource managers are seeking solutions that provide near real-time estimates of [...]

productDescriptionThe data from the beaches and Nowcast results will be provided as well as the option for exporting data excel file for each beach season recorded. The final web product will result in a flexible framework allowing for expansion to other Great Lakes and regional beaches in the future. A USGS Fact Sheet describing the Nowcast will be published.

valueCurrently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. The U.S. Geological Survey (USGS) is working with local and state agencies to expand the use of operational predictive models throughout the Great Lakes. USGS will improve and maintain the New York Nowcast system and refine and expand a data-management system to accommodate additional beaches in New York, the Great Lakes Region and recreational beaches in general. The new system will provide recreational water-quality notifications to the public in 2015 and will be called the New York Nowcast.
