While Colorado River surface water supplies have dominated news headlines recently, Arizona communities face another important water challenge: rapidly declining groundwater levels.
Arizona relies on groundwater for about 40% of its water supply, yet groundwater resources outside of the state’s biggest urban areas are largely unprotected and unregulated, posing a risk to long-term economic growth, community resilience and healthy flowing rivers.
HB 2467, a bill that was signed by Gov. Doug Ducey on May 22, takes an important step forward to address groundwater challenges in Mohave and La Paz counties.
Mohave County is in northwest Arizona and includes western portions of the Grand Canyon and the city of Kingman on historic Route 66. La Paz County is just south of Mohave and includes the Interstate 10 corridor, part of the Kofa National Wildlife Refuge and important perennial streams. In recent years, residential and other small wells have increasingly seen water levels dropping as more large-capacity wells are drilled for commercial agricultural operations moving into the region, often from outside Arizona.
