DeKalb leaders say they are making progress by reducing major spills and ensuring their wastewater treatment plans are working effectively to release treated water back into the South River. The Georgia State researchers will use a $400,000 National Science Foundation grant to study the ways drinking water and wastewater often are mixed together with naturally flowing water in streams and rivers.
“Knowledge from this study could help the EPA and DeKalb County to prevent untreated sewage from entering the South River and its tributary creeks,” Richard Milligan, a GSU professor who specializes in environmental justice research, said.
DeKalb County was an ideal case to study because half of the county is in the Chattahoochee River basin, which flows to the Gulf of Mexico, and the other half resides in the South River basin, flowing to the Atlanta Ocean, the researchers said.
The county it gets all of its drinking water from the Chattahoochee but drains more than 30 million gallons of water each day into the South River.
