What this trial studies

This clinical trial aims to assess the impact of ultraviolet (UV) light treatment on the incidence of gastrointestinal illnesses in children under 5 who consume untreated water from private wells. Families will be randomly assigned to receive either an active UV device or a sham device, and will report symptoms of illness weekly over the course of one year. The study will also analyze water and stool samples for pathogens to better understand the health risks associated with untreated well water. This research seeks to fill a significant knowledge gap regarding the health effects of private well water in the U.S.

Who should consider this trial

Good fit: Ideal candidates include children under 5 living in households served by untreated private wells in specific counties of Pennsylvania and New Jersey.

Not a fit: Patients who are immunocompromised, have chronic gastrointestinal conditions, or exclusively drink bottled water will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of gastrointestinal illnesses in children by promoting effective water treatment methods.

How similar studies have performed: While this approach is novel in the context of private well water treatment, similar studies have shown success in evaluating water treatment methods for reducing illness.
