The Irreversible Impact Widespread Sewage Sludge Has on our Planet’s Ability to Support Life

Dr. David L. Lewis retired from the U.S. EPA in 2003 as a senior-level Research Microbiologist with 32 years of service. He also served on the Graduate Faculty of the University of Georgia. His research on public health has been published in Nature, Lancet and other leading scientific and medical journals. Dr. Lewis’s book, Science for Sale, covers the history of affects of sewage sludge. Dr. Lewis received the 2000 Science Achievement Award by the EPA, and the 2018 Distinguished Service Award by the Sierra Club and the Center for Environmental Law and Policy..

Industrial Waste Spreading

Patty Martin is the former Mayor of Quincy WA, founder of Save Our Soil, and Chair of Northwest Toxic Communities Coalition. The book, Fateful Harvest (2001), chronicled her fight to expose the use of hazardous waste-derived fertilizers in agriculture and the chemical industry’s efforts to shut her up. In 2013, Patty received the Environmental Justice Award from the Sierra Club and has fought against land application of sewage waste in Washington state. Martin spoke on the non-sludge hazardous wastes used in fertilizer (coal ash, mining waste, nuclear fuel processing waste, etc.). Sixty times as much of it is used on food compared to sludge.

3 Adventures Organizing Citizens to Stop Sewage Sludge Land Spreading

Ed Kenney is a consummate environmental activist who has organized teams of volunteers to clean up the debris and planted trees for large restoration projects. He was awarded Conservationist of the Year by Black Hills Audubon Society in 1992. More recently, Ed brokered a multi-million dollar agreement between Joint Base Lewis-McChord military base, the City of DuPont, CalPortland and six conservation groups to restore over three miles of Sequalitchew Creek. He has fought against land application of sewage waste in Washington state.
