Potomac River Advisory Lifted After Sewage Spill
2 Mar
Summary
- Potomac River advisory lifted six weeks after a sewage pipe collapse.
- Over 240 million gallons of sewage spilled into the waterway.
- Water quality in D.C. has returned to safe recreational limits.
The District of Columbia has lifted its advisory for the Potomac River, approximately six weeks after a significant pipe failure released over 240 million gallons of sewage. D.C. Water has largely contained the spill with temporary fixes, and recent water quality tests indicate that E. coli levels in D.C. waters have fallen below safe limits for recreation. Officials are investigating the cause of the pipe's collapse, with D.C. Water CEO David Gadis suggesting that the weight of backfill rocks or thinning pipe walls may have been contributing factors.
Despite these assurances, the full repair and remediation process is ongoing, with federal contributions secured for the effort. D.C. officials maintain that fishing and boating are now safe in the Potomac. The region's drinking water remains unaffected, as the intake facility for the Washington Aqueduct is located upstream from the spill site. Furthermore, a downstream intake was not operational during the incident.
While D.C. has reopened its waters, Maryland plans to lift a shellfish harvesting closure on March 10, pending further testing. Virginia, however, has not yet made a decision on its advisory, cautioning the public to avoid recreational activities. Concerns about contamination in river sediment are also being addressed, with ongoing testing for pathogens like E. coli. D.C. Water is conducting daily water quality sampling, and repairs to the collapsed pipe are anticipated to conclude in mid-March, with further rehabilitation work to follow.
