Drinking fountains in schools provide the primary water access for students throughout the school day. PFAS in school drinking fountains exposes children during their most developmentally vulnerable years and in an environment where parents cannot easily provide filtered alternatives. Addressing school water PFAS requires testing, appropriate remediation, and clear communication with school communities.
Why School Fountains May Differ From Tap Concentrations
PFAS concentrations at school drinking fountains can differ from utility source water measurements for several reasons. Internal building plumbing may contribute additional contaminants. Drinking fountains that see intermittent use may have longer water stagnation times between uses, during which PFAS can concentrate through minor evaporation or interact with plumbing materials. First-draw testing (without pre-flushing) captures the water that students actually drink and may differ from flushed samples used in utility monitoring.
Testing Protocols for Schools
EPA and several state agencies have developed school drinking water testing guidance that addresses PFAS alongside lead. First-draw sampling at each drinking water outlet — without flushing before sampling — captures the actual exposure water. Results are compared against regulatory MCLs, and outlets exceeding limits should be taken out of service immediately pending remediation. Schools should publish testing results transparently and communicate results to parents regardless of outcome.
Remediation Options
For schools with PFAS-affected drinking fountains, point-of-use certified filters installed directly on drinking fountain outlets provide immediate protection at relatively low cost. Many certified drinking fountain filter systems are available specifically designed for school and commercial fountain applications. Whole-building treatment addresses all water simultaneously but at higher cost. Interim measures while permanent remediation is implemented include providing sealed bottled water or directing students to filtered water stations.
