Nitrates in Tap Water Put 1 in 5 Americans at Risk, New Report Finds
TL;DR
EWG’s 2021–2023 analysis of nearly 50,000 public water systems finds about 62 million Americans (roughly 1 in 5) may drink tap water with nitrate levels linked to health risks; millions exceed 3 mg/L and thousands exceed 5 mg/L, with some wells reaching much higher levels. Nitrates largely come from agricultural fertilizers and manure, and private wells aren’t covered by EPA rules. Mitigation includes home reverse-osmosis filters, but tighter regulations and consumer awareness are urged, as bottled water is not a guaranteed fix.
