ATLANTA (AP) — Georgia residents returning Wednesday to homes soaked by days of torrential rains were warned of a hidden danger — disease-causing bacteria and jagged debris harbored by stagnant, murky water. Standing water up to several feet deep was still pooled in some neighborhoods, including parts of Cobb County in the Atlanta area. Anyone venturing into a flooded yard or basement should wear rubber waders and surgical gloves, and items that were submerged should be cleaned with disinfectant, state emergency officials said.
