The following letter, submitted by concerned scientists, really underscores the need for the Precautionary Principle to be applied here - there are far too many possible dangers, with very scary outcomes. Far better to put land-application on hold and look for safer alternatives!!
Scientists' Open Letter on the Dangers of Biosolids
The land disposal of sewage sludge has resulted in significant controversy, and a resistance movement is rightfully building to this misguided policy. Quite simply, the science doesn't support
the disposal of sewage sludge across the landscape. The supposed benefits are more than offset by the risks toward human and environmental health.
I love how eloquently these two leading crusaders sum up the Biosolids issue - (this is why we are all fighting so hard for change !!!)
Professor Snyder (Harvard PhD)
"Biosolids applied to land is probably the most pollutant-rich material generated in the 21st century. It contains hazardous industrial waste, pharmaceuticals, carcinogens, neurotoxins, solvents, and a host of other chemicals , metals, and superbugs. Serious life-threatening illnesses, animal deaths, polluted... wells, permanently poisoned soil all have been linked to this unsafe practice. Biosolids regulations are full of loopholes. The government agencies that are supposed to protect human health and the environment have been captured by the industries and cities who profit from this convenient method of sludge disposal. No credible science supports the practice of spreading toxics-containing waste on the land where we graze our animals or grow our food. A growing body of credible peer reviewed science indicates that the land cannot clean up biosolids. Instead toxic and persistent industrial pollutants accumulate in the soil, leach into groundwater, or are picked up by plants."
Jim Poushinsky MSW (Ottawa) - "The spreading of toxic and pathogenic sewage biosolids on agricultural lands and hence into the food chain and environment is the best kept secret of our time. It is a secret because the sewage spreading lobby of government and industry knows full well that if this becomes common knowledge the people will not stand for it and insist it be stopped. "
