Water Filtration

Nitrate, a chemical most commonly used as a fertilizer, poses an immediate threat to infants when it is found in drinking water at levels above the national standard. Nitrates are converted to nitrites in the intestines. Once absorbed into the bloodstream, nitrites prevent hemoglobin from transporting oxygen. (Older children have an enzyme that restores hemoglobin.) Excessive levels can cause “blue baby syndrome,” which can be fatal without immediate medical attention. Infants most at risk for blue baby syndrome are those who are already sick, and while they are sick, consume food that is high in nitrates or drink water or formula mixed with water that is high in nitrates. It is extremely important to avoid using water with high nitrate levels for drinking. This is especially important for infants and young children, nursing mothers, pregnant women and certain elderly people. Also, when you know nitrates are present in your drinking water, Do NOT Boil the water in an attempt to reduce nitrates. Boiling water contaminated with nitrates increases its concentration and potential risks. If you are concerned about nitrates, talk to your health care provider about alternatives to boiling water for baby formula. Using a water filter especially designed to remove nitrates is also recommended. Countertop, under sink and in-line refrigerator filters, both ultrafiltration type and reverse osmosis, will do an excellent job of removing nitrates and other similar contaminants from drinking water.
