The inaugural Anacostia River Splash was postponed due to exceeding E. coli levels in the water, detected after recent rainfall. The event, originally scheduled for Saturday, will now take place on July 13. This would have marked the first time in over 50 years that residents could swim in the Anacostia River legally. Nearly 200 people had registered for the event. The water quality samples taken on Wednesday were under 100 for E. coli, but spiked to 500-600 on Friday. The decision to postpone was made for safety, marking the third postponement since the event was initially scheduled last July. Despite the setback, organizers remain committed to ensuring the event is safe for all participants.
