Morgan has tried cases involving alleged PCE, hexavalent chromium, and petroleum contamination. He is currently the managing partner of Barg Coffin Lewis & Trapp, LLP.

Environmental law is among the most fascinating topics facing mankind. It is about how we balance our need to use resources today with the long-term health of our species and our planet. For me, it also marries several interests – scientific interests in geology and chemistry, which I studied in college, and law and economics, which is at the heart of much of environmental law. Today, my practice encompasses a broad range of legal, scientific and technical issues, including contamination of air, soil and water, greenhouse gas emissions and brownfields.
