At her own drinking well, the arsenic level jumped from 13 to 20 µg/L this year, she said."

"Since arsenic is not limited to private wells, public agencies have responded, too: The city of Alamosa built a new water treatment plant in 2008 to bring its arsenic levels into compliance with federal standards. In 2020, the state of Colorado sued an Alamosa mushroom farm for exposing its workers to arsenic in tap water."

As the West grapples with a megadrought, its driest spell in at least 1,200 years, rising levels of arsenic — a known carcinogen — in Colorado’s San Luis Valley offer clues to what the future may h…
