If the Trump plan survives legal challenges, polluters would no longer need a permit to release contaminated water into ephemeral streams and wetlands that aren’t immediately adjacent to protected waters. This would, according to New Mexico’s Environment Department, eliminate about 40% of the state’s water pollution permits, including those held by wastewater treatment plants, hard-rock mines and coal mines.
The effect this could have on the state’s drinking water is illustrated most starkly at Los Alamos National Laboratory, the former Manhattan Project site that serves as a center of the country’s nuclear research and development.
