Could toxic chemicals along the Ohio River be a danger to our drinking water?

Arsenic. Lead. Mercury. Sulfuric Acid.

At a closed Duke Energy power plant, at least 10 billion pounds of coal ash containing these toxins and more are sitting on the banks of the Ohio River – a source of drinking water for more than 5 million people.

How the polluted ponds got there is a story that began long before environmental laws were created to keep people and drinking water safe from toxic waste.
