Overview
- Environmental restoration began under a National Park Service permit, with contaminated brush and soil removal underway and work paused during rainfall to prevent recontamination.
- Crews finished cleaning the upstream pipe segment and are preparing to spray geopolymer to stabilize the damaged interceptor before a planned sliplining phase.
- D.C. Water increased around‑the‑clock pumping capacity to keep sewage out of the river as emergency repairs target completion in mid‑March.
- D.C. Health moved to daily sampling at multiple Potomac and Anacostia sites, sending samples to an EPA laboratory with results returning in about two days.
- Officials report no additional overflows to the Potomac since Feb. 9 and say drinking water remained unaffected, while the Potomac Riverkeeper Network urges broader testing and longer‑term restoration; DC Water says it is coordinating with regulators and stakeholders.
