DC Water, in coordination with the Environmental Protection Agency, is evaluating soil samples from areas directly impacted by the Potomac Interceptor overflows, where the initial clean-up is complete. This includes the drainage channel along Clara Barton Parkway, Rock Run Culvert (Culvert 12), and the unnamed tributary to the Potomac River.

Starting the evening of Friday, March 27, and continuing through the early morning of Monday, March 30, essential repairs will be underway as part of a high-priority project on the Rock Creek Main Interceptor (RCMI) near Rose Park.

DC Water has completed sludge removal on a section of the C & O Canal between locks 13 and 14, which was used as a bypass to divert wastewater around the collapsed section of the Potomac Interceptor and back into the pipe further downstream. Crews are now constructing an access bridge to this section of the canal to allow soil removal to begin.
