Striking images show what the environment looked like before the EPA

Documerica project shows effects of unregulated pollution.

— -- Public concern for the environment led to the creation of the Environmental Protection Agency, which began operations on Dec. 2, 1970.

Its mission? “To protect human health by safeguarding the air we breathe, water we drink and land on which we live,” according to the EPA website.

Here’s a look at some of the most striking images from the project:

In this photo of the Georgetown Gap, taken in April of 1973, raw sewage flows freely into the Potomac River.

This image from June 1972 captures "Old Darky," an Atlas Chemical plant that earned its nickname from the black soot that covered everything nearby.

Additional images from the project are available on the U.S. National Archive's Flickr page.
