Well water worries: UV filters tested to protect kids from diarrhea
NCT ID NCT04826991
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether using a UV light filter on private well water can lower the chance of stomach infections in children under 5. About 900 families in Pennsylvania and New Jersey will either get a working UV filter or a fake one. Researchers will track how often kids get sick and test water and stool samples to understand the link between well water and illness.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Ultraviolet (UV) light water treatment device
- What this could lead to
- If successful, this could show that treating well water with UV light reduces stomach infections in children, providing evidence to guide public health recommendations.
- What could go wrong
- This is an observational-style trial with a sham control, not a treatment study. The UV device may not significantly reduce illness, and results may not apply to other regions or water sources.
