Cynthia Beltran moved to Sunizona with her seven-year-old son last autumn even though the area lacks functional drinking water wells, because it was all she could afford. She cannot afford the $15,000 cost of deepening her well, which dried up last year, and had been paying for a local firm to deliver water in a tanker. But at $100 a week it became too expensive, so now she will be relying on a friend to help her fetch water from her mother’s well. … Nearly 20 wells in Sunizona alone were deepened between 2015 and 2019, after they dried up.
