What this violation means

Nitrate contamination is most acute in agricultural regions where fertilizer and animal waste leach into groundwater. The immediate risk is to formula-fed infants under 6 months — high nitrate levels prevent their blood from carrying oxygen, causing 'blue baby syndrome.' Pregnant women should also avoid high-nitrate water.

Recommended precautions

→Never give untreated high-nitrate water to infants — use bottled water for formula.
→Boiling does NOT remove nitrate. Boiling concentrates it.
→Reverse osmosis, ion exchange, or distillation are the only effective home treatments.
→Private well owners in farming areas should test annually for nitrate.
