Nitrates are present in some groundwater and form when microorganisms break down fertilizers or organic residues. Usually plants take up these nitrates, but sometimes rain or irrigation water can leach them into groundwater. Common sources of nitrate is from fertilizers, manure, municipal waste water treatment and septic tanks. In moderate amounts, nitrate is harmless in drinking water. If people or animals drink water high in nitrate (>10 mg/l), it may cause Blue Baby Syndrome, an illness found especially in infants and pregnant women. This condition disrupts oxygen flow in the blood.
Nitrate can be removed from drinking water by two methods: ion exchange or reverse osmosis. Special anion exchange resins are used that exchange chloride ions for nitrate ions in the water as it passes through the resin.
