Chattahoochee River, Georgia BacteriAlert

Background:   How safe is it to swim, wade, and boat in the Chattahoochee River today? For a highly urbanized river such as the Chattahoochee, much of the answer depends on bacteria levels in the water. This website provides "real time" turbidity data, the estimated Escherichia coli (E coli) bacteria count, the most recent E. coli bacteria counts (sample collected each Thursday), and National...
