Beyond rising fuel costs, the Middle East conflict is creating unexpected challenges for American water systems, with several utilities reporting difficulties maintaining proper fluoride concentrations in public drinking water supplies.
Recent weeks have brought supply chain disruptions affecting water treatment facilities nationwide, reports the Association of Metropolitan Water Agencies. Water systems add fluoride as a dental health measure to combat tooth decay in communities.
The supply issue stems from Israel’s position as a leading global producer of fluorosilicic acid, the chemical compound used in water fluoridation, according to Environmental Protection Agency records. The United States ranks among the world’s top five nations importing this product.
Production capacity has declined at Israeli manufacturing facilities as workers receive military deployment orders, explained Dan Hartnett, who serves as chief policy officer for the Association of Metropolitan Water Agencies.
“That has led to decreased production, and supply shortages for the U.S. market,” he said.
While currently affecting a limited number of utilities, the shortage impacts several hundred thousand residents. Hartnett warned that continued fighting means “there will likely be additional stressors placed on the supply chain, leading to shortages in additional communities.”
Maryland’s WSSC Water, ranking as the nation’s eighth-largest water and wastewater provider, announced fluoride reductions on April 7. The utility decreased fluoride concentrations to 0.4 milligrams per liter from the standard 0.7 milligrams per liter recommendation.
Chuck Brown, representing the utility that serves 1.9 million customers, acknowledged uncertainty about the shortage duration, “but we feel confident that we’ll be able to stretch that out for a couple more months.”
Pennsylvania’s Lititz borough temporarily suspended water fluoridation for several weeks in recent months due to similar supply constraints.
Since fluoride addition remains voluntary for public health benefits, reduced concentrations don’t compromise water safety standards.
Dr. Scott Tomar, a community water fluoridation specialist with the American Dental Association, believes temporary fluoride reductions shouldn’t alarm most residents.
Studies examining communities that discontinued fluoridation programs in Calgary, Canada; Juneau, Alaska; and Israel demonstrate that impacts typically emerge over multiple years rather than months.
“Based on the best available information we have, below about 0.5 milligrams per liter, you’re probably not going to see effective preventive exposure,” he said.
Children face the greatest risk from prolonged fluoride deficiency, Tomar noted, since the mineral reinforces tooth enamel during development and after permanent teeth emerge.
He advises residents in affected areas to maintain twice-daily brushing with fluoride toothpaste and continue regular dental checkups. Anyone concerned about fluoride intake should consult their dentist before considering supplements or alternative treatments.
Studies confirm water fluoridation provides benefits even when fluoride appears in toothpaste and other products. Centers for Disease Control data shows nearly two-thirds of Americans receive fluoridated tap water.
Public health officials historically celebrated water fluoridation as among the most significant health advances of the previous century. The American Dental Association attributes the practice with cutting tooth decay rates by over 25% across age groups.
Despite this track record, fluoride safety misinformation has spread widely. Utah became the first state to prohibit public water fluoridation last year. Health Secretary Robert F. Kennedy Jr. has frequently questioned fluoride safety and opposed its dental health applications.
“The levels we use in the United States is perfectly safe,” Tomar said. “Despite a lot of the misinformation, there are no adverse health effects associated with the levels we use in our drinking water.”
