(Earth Focus: Episode 64) In Juliette, Georgia radioactive water flows from the tap. In Pennsylvania, three adjoining counties battle a rare form of cancer. One thing these communities have in common is their exposure coal ash. Coal combustion powers 40 percent of America’s electricity but generates 130 million tons of coal ash each year.

There is no federal coal ash regulation on the books—only a patchwork of state level standards.
