Put simply, there are towns in Texas where you turn on the tap, and nothing comes out for days. Why? Fracking.
You knew this was going to happen, and you knew it was going to happen in the desert-like South and Southwest. And whether the God-fearing folks in rural Texas knew it or not, when they voted for all those Drill-Baby-Drill Republicans (and Democrats who seek power by imitating them), they voted themselves out of water.
The Guardian (my emphasis and some reparagraphing):
A Texan tragedy: ample oil, no water
Fracking boom sucks away precious water from beneath the ground, leaving cattle dead, farms bone-dry and people thirsty
Beverly McGuire saw the warning signs before the town well went dry: sand in the toilet bowl, the sputter of air in the tap, a pump working overtime to no effect. But it still did not prepare her for the night last month when she turned on the tap and discovered the tiny town where she had made her home for 35 years was out of water.
