CANTON, Kan. — The City of Canton has issued a drinking water warning due to high levels of nitrates which could be dangerous for infants and some other individuals. Nitrate in drinking water can come from natural, industrial, or agricultural sources (including septic systems and run-off). Levels of nitrate in drinking water can vary throughout the year.
The city said Wednesday a water sample collected July 8th showed a nitrate level of 11 mg/l which is above the federal nitrate standard, or maximum contaminant level (MCL), of 10 mg/L. A confirmation sample is being collected to determine if there is a nitrate problem with the water quality. Testing results from that sample should be available in about 30 days.
Canton water should not be given to infants below the age of six months, including use in preparation of formula or juice. Infants below the age of six months who drink water containing nitrate in excess of the MCL could become seriously ill and, if untreated, may die. Bottled water is being provided by the city for vulnerable populations
Symptoms include shortness of breath and blue baby syndrome. Nitrate is an acute toxin to infants less than six months of age. In infants, it can cause a condition known as methemoglobinemia, or “blue-baby syndrome” which can be fatal. The most obvious symptom is a bluish skin coloring, especially around the eyes and mouth.
Other symptoms can include shortness of breath, nausea, vomiting and dizziness. An infant with bluish skin should be taken immediately to a medical facility for treatment. It is safe to bathe or shower in tap water with elevated nitrate levels.
Boiling, freezing, filtering, or letting water stand does not reduce the nitrate level. Excessive boiling can make the nitrates more concentrated, because nitrates remain behind when the water evaporates.
Adults and children older than six months can drink the tap water (nitrate is a concern for infants because they cannot process nitrates in the same way adults can). However, if you are pregnant or have specific health concerns, you may wish to consult your doctor.
