The Department of Public Works in Baltimore is lowering the level of fluoride in its drinking water systems this week, tying the reduction to supply issues caused by the Iran war.

“This is an adjustment driven solely by supply availability,” said DPW Director Matthew Garbark in a statement. “We remain committed to providing safe, high-quality drinking water.”
