A new bill in the state Legislature would require California to review the environmental impacts of a company’s proposal to pump groundwater from beneath the Mojave Desert and sell it to Southern California cities — a controversial plan that was slowed down by President Obama, but which appears to have the backing of the Trump administration. Cadiz Inc. hopes to pump 16.3 billion gallons of groundwater annually in the heart of the desert, about 75 miles northeast of Palm Springs, on land surrounded by Mojave Trails National Monument and near Mojave National Preserve.
