Reviving the river

Industrial growth and raw sewage in the region in the 20th century killed aquatic life in much of the Delaware River and surrounding streams.

A grassroots environmental effort in the '60s resulted in The Clean Water Act and major federal dollars were provided for the upgrades we see today.

Hidden beneath what looks, and smells, like much cleaner water are potential new dangers like plastics, pharmaceuticals and the impacts of climate change.

Reviving the Delaware River took decades and came about through a combination of social need, public outcry, and political will. Here, we look at the river's history.

Since taking office, President Donald Trump has made environmental deregulation a priority.
