What We do

ADEQ stands for the Arizona Department of Environmental Quality. We administer the state’s environmental laws and delegated federal programs to prevent air, water and land pollution and ensure cleanup.

Under the Environmental Quality Act of 1986, the Arizona State Legislature created ADEQ in 1987 as the state’s cabinet-level environmental agency. ADEQ is composed of three environmental programs: Air Quality, Water Quality and Waste, with functional units responsible for technical, operational and policy support.

ADEQ carries out several core functions: planning, permitting, compliance management, monitoring, assessment, cleanups and outreach.

Mission/Vision

To protect and enhance public health and the environment in Arizona.

Through consistent, science-based environmental regulation; and clear, equitable engagement and communication;

With integrity, respect, and the highest standards of effectiveness and efficiency;

Because Arizonans treasure the unique environment of our state and its essential role in sustaining well-being and economic vitality, today and for future generations.
