A sewage spill in the Potomac River northwest of D.C. last week has not affected drinking water in Fairfax County, the local water utility says.
The spill occurred in Montgomery County, Maryland, along Clara Barton Parkway, which hugs the northern edge of the Potomac River near Chesapeake and Ohio Canal National Historic Park. The spill was caused by a DC Water sewer pipe that collapsed late Monday, Jan. 19, shooting sewage out of the ground and into the river.
