FOR WATER TESTING: ARC members collect water samples from three locations along our rowable stretch of the Chattahoochee River: 1) the bridge on Riverside Rd. over Big Creek; 2) the bridge on Roswell Rd. over the Chattahoochee; and, 3) the Fishing Pier on the Chattahoochee just upstream of the Narrows. Potential new volunteers must complete an on-site testing program. In order to fit the Riverkeepers’ testing schedule, all samples must be completed on Thursday Mornings between 7 and 11 AM.
