Overview
- DC Water restored full wastewater flow through the Potomac Interceptor after completing emergency repairs and shutting down the canal bypass.
- EPA took over water‑quality sampling from D.C.’s environment department, with daily results to be posted publicly and analyzed at the agency’s Fort Meade lab.
- Montgomery County lifted most recreational advisories, though officials still warn people to avoid areas near Swainson Island and the Lock 8–14 shoreline where bacteria levels have been elevated.
- Crews are vacuuming sludge from the C&O Canal and finishing a freshwater dam at Lock 14 to help flush remaining contaminants as site remediation continues.
- Public pressure and scrutiny are growing with House investigators seeking answers, a class‑action suit filed March 6, and DC Water holding community meetings on the failure and long‑term fixes.
