<unk>  mostly affects infants under 6 months of age (particularly those under 4 months) due to low hepatic production of<unk> moglobin reductase. The most at-risk populations are those with water sources high in nitrates, such as wells and other water that is not monitored or treated by a water treatment facility. The nitrates can be hazardous to the infants. The link between blue baby syndrome in infants and high nitrate levels is well established for waters exceeding the normal limit of 10 mg/L. However, there is also evidence that breastfeeding is protective in exposed populations.
