Samples are collected weekly and analyzed in Chattahoochee Riverkeeper's Gainesville lab as a part of our Neighborhood Water Watch (NWW) Program. When new sample data is available, Chattahoochee Riverkeeper updates SWIM Guide. Actual E.coli numbers and other data can be viewed at https://nww.chattahoochee.org/DataPage.
A test does not meet water quality standards when a presumptive E. coli level has a EPA Beach Action Value higher than 235 MPN/100ml.
