I have been an Environmental Engineer for over 50 years. It all started when I was 19 and Purdue set me up with 3 professors and together we developed an individual engineering program to become an environmental engineer.
When I was 23 I was the senior technical representative on two wastewater treatment design teams for chemical plants. At 29, I wrote my first book, “Groundwater Treatment Technology”. For the next 30 years I wrote, taught and designed treatment systems for groundwater and soil all over the world.
The one constant during all of this was that biological systems were always the workhorse in removing unwanted chemicals from any environment.
