Arizona Department of Environmental Quality (ADEQ)

About us

The Arizona Department of Environmental Quality administers state environmental protection laws and delegated federal programs to prevent air, water, and land pollution and provide 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.
Our mission is to protect and enhance public health and the environment in Arizona.
