The Washington Suburban Sanitary Commission is reducing fluoride in the water it delivers to 1.9 million customers in Washington’s Maryland suburbs because of supply chain issues caused by the Iran war.
The utility said Tuesday it’s making the reduction at the Potomac and Patuxent water filtration plants, serving its customers in Montgomery and Prince George’s counties, from 0.7 milligrams per liter to 0.4 milligrams per liter.
WSSC Water said the supply chain issue involves the chemical hydrofluorosilicic acid, which is used to fluoridate community water supplies. Fluoridation is intended to help protect residents from tooth decay.
In addition to a drop in domestic production, output from other sources has fallen. That includes a supplier in Israel that has “experienced significant operational impacts,” WSSC Water said.
“This is a temporary adjustment driven solely by supply availability. We remain committed to maintaining safe, high-quality drinking water and will restore optimal fluoride levels as soon as supply conditions stabilize,” said Ben Thompson, director of production for WSSC Water.
The Washington Aqueduct, the federally operated supplier of water to 1 million customers, has not responded to a request for comment from The Washington Times about fluoride supply issues or cutbacks.
In addition to WSSC Water, the town of Lititz, Pennsylvania, 75 miles northwest of Philadelphia, stopped fluoridating its water March 21-26 due to problems with securing hydrofluorosilicic acid.
The town’s officials did not say whether the shortfall was due to lower domestic output or problems getting it from abroad.
