The Arizona Department of Environmental Quality is a mid-sized state agency focused on environmental services in Arizona. Located in Phoenix, it was established by the Arizona Legislature in 1986 in response to groundwater quality concerns. Its mandate is to administer programs that protect public health and the environment, ensuring air, land, and water resources meet healthful regulatory standards. ADEQ collaborates with other state agencies, local governments, utilities, and a range of partners to implement environmental quality initiatives and address community health needs. Recent activities include recycling grants to support education campaigns and partnerships advancing the state's Advanced Water Purification rule, adopted in 2025.
