The Arizona Department of Environmental Quality reported Dec. 6 that it has lifted the Johnson Utilities Drinking water advisory for nitrate.
ADEQ notified Johnson Utilities (PWS 11182) customers on Dec. 2 to not provide water to infants under of the age of 6 months or use the water to make infant formula because of elevated nitrate levels. ADEQ has confirmed the problem has been resolved and tap water can be given to infants under the age of 6 months, according to a press release.
On Dec. 6, ADEQ received confirmation from Johnson Utilities that its sample collected on Nov. 30, 2016, demonstrated the nitrate level met the federal drinking water standard (lower than the Maximum Contaminant Level of 10 mg/L at 7.15 mg/L). This sample was analyzed using certified analytical methods.
Customers can call Katherine Nierva with Johnson Utilities at 480-998-3300 if they have questions.
ADEQ asks that the public share this information with all people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools and businesses). They can do this by posting this notice in a public place or distributing copies by hand or mail.
