Regulatory Context
Well Drilling Regulations in Arizona
Water well drilling contractors in Arizona must hold a current state well-driller license and follow state well-construction standards that protect groundwater and aquifers. Look for contractors licensed by the Arizona well-driller licensing board and members of the National Ground Water Association (NGWA). Drilling, casing, and well-completion work is regulated by state groundwater-protection programs and state well-construction codes. Private-well construction is overseen at the state and local level, not by the federal Safe Drinking Water Act, which governs public water systems. Contact your state well-driller licensing board for specific licensing and permit requirements in your area.
