Army engineers to put end to dumping sludge into the Potomac River

The U.S. Army Corps of Engineers will spend $96 million to build a new processing facility in Northwest that should put an end to the periodic, massive discharge of sludge into the Potomac River.

The 68,559-square-foot residuals-processing facility, slated for 7.4 acres off Little Falls Road near the Dalecarlia Reservoir, immediately north of Sibley Memorial Hospital, should allow the Washington Aqueduct to meet a Clean Water Act permit restricting the expulsion of sediment and aluminum sulfate into the river.
