“Arizona Gov. Katie Hobbs said a newly released study of the Phoenix metropolitan area’s groundwater showed a potential shortage looms. To safeguard supplies, current developments that have been approved can be constructed, but ones that have yet to be approved will have to show alternate water sources. Developers must show state officials they have an alternative ‘assured water supply’ for 100 years from non-local groundwater… The study found that 4% of the metro area’s demand for groundwater, nearly 4.9 million acre-feet, cannot be met over the next century.”
