New Mexico’s rivers are most threatened waterways in US, report finds

Supreme court ruling left more than 90% of state’s surface waters with no pollution protections, since they don’t run continuously

New Mexico’s rivers, which include the Rio Grande, Gila, San Juan and Pecos, are America’s most threatened waterways, according to a new report. This is largely due to a 2023 US supreme court decision that left more than 90% of the state’s surface waters without federal protections from industrial pollution, according to state officials.

“Virtually all the rivers in New Mexico are losing clean water protections,” said Matt Rice, the south-west regional director of American Rivers, the conservation group that publishes the annual list. “It has the most to lose, and the threat is particularly acute there.”
