The flesh-eating bacteria affecting Aimee Copeland might not be the one you should worry about in Georgia's water.

Testing the water and soil at the Chattahoochee River, Neil Tarver with the University of Georgia's cooperative extension program says lots of bacteria live in the water.

He says E. coli is more common and much more dangerous.

"Fresh water like this is probably going to be very low risk," Tarver tells Channel 2 Action News.

Copeland contracted the bacteria, Aeromonas hydrophila, when she injured her leg while zip-lining. The bacteria infected the wound, causing a flesh-eating disease called necrotizing fasciitis.

"If you get injured in the water," Tarver says, "get treatment immediately."
