This is simply a lie. We were briefed by one of the guys running for SRP water board. AZ has as much ground water as it had in 1970. We have, despite fourfold increase in population, actually managed to conserve more water recently. Management of the lakes and canals and Colorado River Water is excellent, contra CA.
This is the Slimes trying to raise a Global Warming hoax claim.
I moved to Tucson in 1968. I left in 1978. During that time we observed stretches of I-10 between Tucson and Phoenix crumple due to land subsidence, due to dropping water tables due to groundwater use. Absolutely no way this politician’s words are true.
