Nitrites can be harmfull to infants below the age of six (6) months who drink water from a supply higher than the maximum allowable numbers. Some infants may become seriously ill and if untreated, may die. Symptoms include shortness of breath and blue baby syndrome.
Blue Baby Syndrome is indicated by blueness of the skin.
Symptoms in infants can develop rapidly, with health deteriorating over a period of days. If symptoms occur, seek medical attention immediately.
Do not use water for mixing formula for children under six (6) months of age, use bottled water low in nitrites until the situation is resolved.
Do not boil water containing high nitrites. Boiling, freezing or letting water stand will NOT reduce the nitrite level. Excessive boiling can make nitrites more concentrated.
Adults and children older than six months can drink tap water (nitrites are a concern for infants six months and younger because they can't process nitrites in the same way adults can).
If you are pregnant or have specific health concerns, you may wish to consult your doctor.
