CNN — A boil water advisory issued Wednesday for Washington, DC, and Arlington County, Virginia, has been lifted, the District of Columbia Water and Sewer Authority and Arlington County said Thursday. The advisory was issued Wednesday due to an increase in algae blooms in the Potomac River, as the nation’s capital prepared for its annual Fourth of July celebrations. Advisories included Washington, Arlington County, the Pentagon, Arlington National Cemetery and Reagan National Airport. The Army Corps of Engineers said the advisory was prompted by elevated cloudiness in the water supply caused by increases in algae blooms in the Potomac River. “Upon observing the increase in algae and resulting turbidity today, Washington Aqueduct staff implemented additional mechanical and chemical treatment solutions to help meet system water supply demands and (Environmental Protection Agency) standards,” the Army Corps said in a statement. Turbidity is a measure of cloudiness in water the EPA says can be used to assess water quality and filtration effectiveness to indicate whether disease-causing organisms could be present.
