The Arizona Legislature established the Arizona Department of Environmental Quality (ADEQ) as the state’s environmental regulatory agency
under the Environmental Quality Act of 1986. ADEQ’s mission is to protect and enhance public
health and the environment in Arizona. The department achieves this mission by administering
the state’s environmental laws and delegated federal programs to prevent pollution of the air,
water, and land, and to ensure clean up of such pollution when it occurs.
ADEQ's goal is to lead Arizona and the nation in protecting and enhancing the environment and improving the quality of life for the people of our state. The agency helps Arizonans respect the balance between the natural world and the people who depend on it for sustenance, prosperity and a fulfilling quality of life.
The department is composed of four programs: air quality, water quality, waste, and administration. The programs carry out the core functions of the agency: pollution control, monitoring and assessment, compliance management, cleanups, eduction, outreach and financial assistance, and policy development.
ADEQ ensures that businesses and facilities operate according to state and federal environmental laws and regulations and the department offers a variety of assistance to bring about compliance. The agency also conducts inspections on a routine basis and in response to citizen complaints.
ADEQ engages Arizonans to keep them informed and encourages participation in environmental planning and decision-making. We strive to educate, inspire and assist citizens by promoting environmental awareness through public involvement activities and providing useful tools and resources.
