Environment

Back in the 80s, the Environmental Protection Agency began requiring power companies to install "scrubbers" in the smokestacks of their coal fired plants to capture pollutants before they got into the air. And that did a reasonable job of cleaning up the air we breathe.

But it damaged the water we drink because all that lead and arsenic and selenium trapped in the smokestacks had to go somewhere. It went, unregulated, into thousands of miles of rivers and streams, making power plants the worst water polluters in the nation.
