D.C. Fire and EMS investigated the smell, which was concentrated around the Foggy Bottom area, and later said that they “believe the Army Corps of Engineers drained a catch basin” in Georgetown, “resulting in stink.”
Via Twitter, Arlington residents told us where they caught a whiff of the foul odor.
“Something did smell odd near Virginia Square,” one Twitter user told us. Two other users agreed that Virginia Square was particularly odorous.
“Noticed the smell around Lyon Village,” said another Twitter user. “Particularly bad near Lee Hwy & Spout Run.”
“Crystal City was a little odd for a bit but that could just be normal Crystal City,” said yet another.
Others reported the smell along the GW Parkway, Lee Highway and Route 50, as well as in Hayes Park.
