Is Oro Valley’s water supply safe? I heard that another town’s water supply recently tested positive for contaminants.

Recently, a neighboring jurisdiction’s water tested positive for two unregulated compounds. We can assure our Oro Valley Water Utility customers that these compounds have NOT been detected in our water system or water supply.

The Town of Oro Valley tests for 112 regulated contaminants and other water quality parameters, as required by the United States Environmental Protection Agency (EPA). In addition, the Oro Valley Water Utility voluntarily tests for various unregulated contaminants that could be regulated at some point in the future. Unregulated contaminants are those that the EPA is studying to determine what levels could be detrimental to human health. The EPA establishes advisory guidelines (rather than maximum contaminant levels) for these compounds.

Oro Valley will continue to monitor for regulated and unregulated contaminants to ensure a safe water supply system. If you have any questions about your water, please contact the Oro Valley Water Utility at 520-229-5000.
