The EPA Alumni Association, has published an interactive report entitled Protecting the Environment: A Half Century of Progress. The report tells "the story of our nation's environmental program for those who don't know or remember it", and it "presents an overview of the environmental problems that existed, the major actions taken, and the progress made as well as the challenges that remain."
Seven essays were written in order to support the main report. The essays detail the improvements made in the environment since the 1970s in the areas of Air, Water, Drinking Water, Waste Disposal, "Superfund" land cleanup, Pesticides, and Toxic Substances. Links to the supporting essays are provided below.
