Surface Water Protection

Waters of Arizona | Surface Water Protection

A change in the federal definition for a Waters of the United States (WOTUS) in the Navigable Waters Protection Rule became effective on June 22, 2020 | View ADEQ's WOTUS Page >

ADEQ acknowledges that the rule narrows protection for some Arizona waterways. We are developing a "local control approach" at the state level to potentially address any gaps and protect Arizona’s important and precious surface water resources.

Through a collaborative stakeholder process, ADEQ is conducting community engagement and Tribal consultations to hear from people throughout Arizona to develop a state surface water protection program outline. Legislative approval will be necessary prior to any program going into effect in Arizona.
