Dr. David Lewis is a former senior research microbiologist with the U.S. Environmental Protection Agency’s Office of Research & Development. He is the only EPA scientist to publish first-authored research articles in Nature, Lancet and Nature Medicine.
As a senior-level (GS-15) research microbiologist for the EPA’s Office of Research & Development, Dr. Lewis used DNA fingerprinting in the late 1990s to study the effects of global climate change on the breakdown of pesticides by bacteria. This research, which he published in Nature – International Weekly Journal of Science, was awarded the EPA’s Science Achievement Award. EPA officials who developed the Agency’s sewage sludge regulations, however, moved to shut down his research when he began investigating illnesses and deaths linked to EPA programs promoting the agricultural use of processed sewage sludge. Nevertheless, his research in this area prompted the Centers for Disease Control and Prevention to issue guidelines protecting workers handling processed sewage sludge. Dr. Lewis was ultimately fired from the EPA.
Kohn, Kohn & Colapinto has represented Dr. David Lewis in his successful campaign to force the EPA to apply appropriate health and safety standards to land applied sewage sludge. In 2002 the EPA Office of Inspector General validated many of Dr. Lewis’ safety concerns.
