Sen. Bernie Sanders vowed Tuesday that if elected president in 2020, he would create national clean drinking water standards forcing corporations to stop contaminating the nation’s water supply with dangerous chemicals.

“Corporate greed is threatening one of the most basic necessities of life: clean water,” Sanders said in a statement to the Associated Press. “Not only will we support state efforts to enforce stronger clean water laws, we are going to create federal clean water standards that force these companies to clean up their mess.”

Sanders, one of the leading contenders for the 2020 Democratic presidential nomination, told AP that his national standards would target perfluoroalkyl and polyfluoroalkyl substances (PFAS) as well as other hazardous chemicals.

The goal of the standards, Sanders said, would be to guarantee clean drinking water “as a human right.”
