School Water Safety Lookup — Check Your School District

Yes, it is more widespread than many realize. A 2018 GAO report found that 43% of school districts tested for lead and, of those, 37% found elevated levels. Many older schools built before 1986 have lead solder in plumbing, and even newer buildings can have fixtures that leach lead. The problem affects all 50 states.

Schools typically collect first-draw water samples from drinking fountains and kitchen taps after water has sat stagnant for 8 to 18 hours, usually overnight. Samples are sent to EPA-certified laboratories for analysis. The EPA's 3Ts guidance (Training, Testing, Taking Action) recommends testing every outlet used for drinking or cooking.

The EPA recommends an action level of 15 parts per billion (ppb) for lead in school drinking water, though the American Academy of Pediatrics advocates for a stricter threshold of 1 ppb, noting that no level of lead exposure is considered safe for children. Several states have adopted levels stricter than the federal recommendation, ranging from 5 to 15 ppb.

Parents can request their school's water testing results, which are public records in most states. If testing has not been done, parents can formally request testing through the school board. At home, sending children with a filled water bottle is a simple precaution. Advocating for NSF-certified point-of-use filters on school fountains is one of the most effective long-term solutions.

It depends on the age of the plumbing, the fountain model, and whether filtered bubblers have been installed. Fountains connected to older lead-soldered pipes or with brass components pose the highest risk. Running the water for 30 seconds before drinking can reduce lead levels significantly. Schools that install NSF 53-certified filters on fountains can reduce lead to below 5 ppb.
