Questions about this page

Does this page list every boil water advisory in Arizona?

No. We do not read Arizona DEQ's advisories into this page, so nothing on it is a list of what is in force. What this page carries instead is where those advisories are published and which water systems our own database holds.

Where are boil water advisories for Arizona published?

Arizona DEQ publishes its own list of active advisories, and this page links to it. We checked it on 22 August 2026. Arizona's site refused every automated client we tried on 22 August 2026, so we confirmed this page's address and character against the live search index rather than reading it ourselves. Open it in a browser for the current list.

How many water systems does this page cover?

Our database holds 341 public water systems in Arizona. That is a count of what is in our database, not a count of every public water system in the state. Advisories are counted by water system, keyed on the system's federal identifier, and never by the number of separate notices one system has been given.

Is anything on this page a verdict about whether the water is safe?

This is not a statement that your water is safe. We do not read this state's advisories, so this page cannot tell you whether one is in force. Your utility is the authority for your own water.
