ADEQ Drinking Water Warning

ADEQ learned today that drinking water test results of Johnson Utilities water exceeded the federal drinking water standard for nitrate. Because Johnson Utilities has not contacted ADEQ or responded to our inquiries, ADEQ is not able to verify whether Johnson Utilities has completed the required notification to its customers about this important water quality concern.


Water sample results collected Oct. 27, 2016, and Nov. 21, 2016, showed nitrate levels of 12 mg/L and 11.4 mg/L, respectively. This is above the nitrate standard, or maximum contaminant level (MCL), of 10 mg/L. Nitrate in drinking water is a serious health concern for infants less than 6 months old.

Nitrate in drinking water can come from natural, industrial or agricultural sources (including septic systems and runoff). Levels of nitrate in drinking water can vary throughout the year.

What to do? What does this mean?

  • DO NOT GIVE THE WATER TO INFANTS. Infants below the age of 6 months who drink water containing nitrate in excess of the MCL could 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
  • Water, juice, and formula for children under 6 months of age should not be prepared with tap water. Bottled water or other water low in nitrates should be used for infants until further notice.
  • DO NOT BOIL THE WATER. 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 6 months can drink the tap water (nitrate is a concern for infants because they can’t 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.

What is being done?

ADEQ is unable to determine what corrective action Johnson Utilities may be performing at this time and is continuing attempts to contact the company to determine what actions they have taken.

ADEQ urges Johnson Utilities' customers who have questions to contact the company directly:
