As the Washington Aqueduct performs its annual spring cleaning, the water treatment facility will switch from chloramine to chlorine between March 26 and May 7. During that time, residents may notice an unusual smell or odor.
According to a press release, the switch is used to "clean and maintain" the water distribution systems in D.C., Arlington County and Falls Church.
To try to eliminate or at least reduce the odor and taste, water authorities recommend "running the cold water tap for approximately two minutes and refrigerating cold tap water for a few hours," according to the press release.
