A push for nuclear power is fueling demand for uranium, spurring the opening of new mines. The industry says new technologies will eliminate pollution from uranium mining, but its toxic legacy, particularly in the U.S. Southwest, leaves many wary of an incipient mining boom.

Yesterday, the feds signaled their approval for a long-awaited agreement between the Colorado River states — collectively, the lower basin states (Arizona, California, and Nevada) will reduce our water use by 3 million acre-feet by 2026. The hope is that we’ll be able to replenish our crucial reservoirs, including Lake Mead, the source of 90% of our city’s water. But damming rivers to create reservoirs isn’t without problems. So… was creating Lake Mead in the first place a mistake? Today, we’re bringing back a conversation co-host Dayvid Figler had with UNLV hydrologist Dr. David Kreamer, who explains the history of Lake Mead’s creation and why reservoirs can be so essential for cities — but also controversial.

An investigation from the Howard Center at Arizona State University uncovered the coming electric battery revolution in America will require billions upon billions of gallons of water to mine lithium. Many of the new U.S. mines will be located in the drought-prone American West.
