First seen Jun 25, 2026 · Last updated Jun 25, 2026
Summary
This study provides American Indian households in North and South Dakota with a special water filter to remove arsenic from their drinking water, plus extra educational visits to help families use it correctly. The goal is to see if this combined approach can lower the amount of arsenic in people's urine, which is a sign of exposure. The trial involves 57 households and is currently active but not recruiting new participants.
