Rain storms generally produce increases in streamflow and river turbidity within the Chattahoochee River. Statistical analysis showed that river turbidity was strongly related to streamflow at both Chattahoochee River sites. Furthermore, both total coliform and E. coli bacteria are strongly related to streamflow-adjusted river turbidity concentration at the Norcross and Atlanta sites. In contrast, E. coli concentrations were not related to river turbidity at the Panola Creek site. Although streamflow data were not available for Panola Creek, streamflow may govern bacteria transport in Panola Creek; whereas, rainfall-generated turbidity may govern bacteria movement in the Chattahoochee River. |
