biosolids that are left over from human waste that is removed from sewage water. Sewage sludge is known to contain not only large concentrations of toxic heavy
metal, but also dangerous disease bearing pathogens like E. coli, Salmonella, norovirus, and a host of other contaminants. Sludge is also known to contain
measurable levels of environmentally persistant chemicals such as polychlorinated biphenyls, dioxins, asbestos, PCBs, and hundreds of other toxins. Residual
pharmaceuticals and human hormones are among the other dangers of contaminants contained within sludge.
municipalities to begin disposing of it in landfills. Given the relative difficulty cities and municipalities have faced in disposing of this growing waste problem,
several companies embraced and began marketing it as a “nutrient rich” fertilizer. Biosolids were presented as a no to low cost alternative for farmers. This
process of spinning and rebranding sludge into beneficial fertilizer is well documented by authors John Stauber and Sheldon Rampton in their book, Toxic Sludge is
Good for You.
spinach, cabbage, Swiss chard, and carrots have all been shown to accumulate toxic metals and/or toxic chlorinated hydrocarbons when grown on soils treated with
sewage sludge. In some instances, toxic organics contaminate the leafy parts of plants by simply volatilizing out of the sludge. Small mammals have been shown to
accumulate heavy metals after sewage sludge was applied to forest lands.
including hydrologists for the U.S. Geological Survey, tested an eastern Colorado wheat field that used treated sludge from a Denver sewage treatment plant.
Chemicals in antibacterial soaps, cleaners, cosmetics, fragrances and prescription drugs such as Prozac and Warfarin not only persisted in the topsoil, but migrated
contaminants after digestion, we feel there is no solid evidence that worm fed composted sludge material is any safer, or fit as a fertilizer. Beware! Many
inexpensive or value-priced brands of vermicast & vermicompost products are produced using sewage sludge.
