Nitrates are formed when nitrogen combines with oxygenated water. Nitrates come from fertilizers, manure, naturally occurs in plants and vegetables, septic systems, and municipal sewage sludge.
A child that is exposed to an increased amount of nitrates is also at risk for a serious condition called “blue-baby syndrome” or methemoglobinemia. This condition is due to a lack of oxygen which causes the skin to have a bluish-gray appearance. Other risks include thyroid disease, diabetes, and certain cancers.
Water should be checked regularly and the levels of nitrates should be under 10 mg/L as recommended by the EPA.
