 Officials must first confirm water quality results. Then participants will be allowed to swim briefly in Anacostia off the Kingman Island dock next to the Benning Road Bridge. That will be during a designated 20-minute time slot. This is going to be the third time trying the event after it was canceled previously. Right now it's sold out. We'll have a reporter at the event. Keep it here with WTOP for all the news about that dip.
