A sulfurous odor was reported Tuesday night in many sections of Washington near the Potomac River, as well as in Arlington, authorities said.
The smell was noted in Foggy Bottom and Georgetown as well as along the Southwest Waterfront, in park areas near the river, and in Anacostia, according to Pete Piringer, spokesman for the D.C. fire and emergency services department. Arlington County’s emergency communications center said reports were also received there.
Piringer said authorities were trying to find the source of the odor. He said they were investigating whether the cleaning or draining of sewage or water supply facilities might have created the smell.
Last week the smell of smoke in parts of the Washington area was attributed to a fire in the Great Dismal Swamp in southeastern Virginia.
It was not immediately clear if that fire also caused the smell detected Tuesday night.
