BacteriALERT celebrates 20 years of monitoring the Chattahoochee River

The Chattahoochee River BacteriALERT program is celebrating 20 years! This partnership between the USGS, National Park Service, Chattahoochee Riverkeeper, City of Roswell, and Cobb County provides timely notification of potentially elevated levels of fecal bacteria to recreational users of the Chattahoochee River within the Chattahoochee River National Recreation Area (CRNRA). Real-time data at USGS stations are used to estimate levels of Escherichia coli (E. coli) concentrations using a predictive model developed by the USGS from water samples collected by the Chattahoochee Riverkeeper and National Park Service. This provides the recreational user a near real-time assessment of the potential health risks of water-based recreational activities on the Chattahoochee River within the Park boundaries.
