Monitoring coliform bacteria in a Piedmont river arising from the Appalachian region of Northern Georgia - Results: E.coli

One goal of the BacteriALERT program is the real-time estimation of E. coli bacteria concentration using real-time monitoring of stream turbidity. To that end, total coliform and E. coli bacteria levels in Panola Creek, the background site, and two sites on the Chattahoochee River were analyzed in relation to changes in streamflow and stream turbidity.
Median concentrations of total coliform and E. coli bacteria at Chattahoochee sites.
Median concentrations of total coliform and E. coli bacteria were higher at the Atlanta site on the Chattahoochee River (6,000 and 120 MPN/100 mL, respectively) than at the minimally impacted Panola Creek site (3,500 and 120 MPN/100 mL) or the Norcross site on the Chattahoochee River (1,200 and 65 MPN/100 mL). However, maximum concentrations of both bacteria were highest at the two Chattahoochee sites.		 Fifteen percent of the 214 E. coli bacteria samples at the Norcross site on the Chattahoochee River exceeded 235 MPN/100 mL
Fifteen percent of the 214 E. coli bacteria samples at the Norcross site on the Chattahoochee River exceeded 235 MPN/100 mL, the USEPA criteria for streams with recreational uses; while at the Atlanta site, the USEPA criteria was exceeded in 32 percent of the 217 E. coli samples.
