US EPA’s 503 sludge rule (1993) allows treated sewage sludges, aka biosolids, to be land-applied to farms, forests, parks, school playgrounds, home gardens and other private and public lands. According to a recent EPA survey, biosolids contain a wide range of mutagenic and neurotoxic chemicals, which are present at a million-fold higher concentrations (ppm versus ppt) compared with their levels in polluted air and water (1). Biosolids contain all of the lipophilic (fat-soluble) chemical wastes that once polluted our rivers and lakes, but which now settle out at sewage treatment plants and become concentrated in sewage sludges. Most biosolids contain ppm concentrations of heavy metals, including chromium, lead, and mercury. They contain similarly high levels of polycyclic aromatic hydrocarbons (PAHs) and semi-volatiles, such as bis (2-Ethylhexyl) phthalate, Benzo(a)pyrene), and polybrominated diphenyl ether congeners (PBDE flame retardants). Most biosolids also contain pathogenic agents and ppm levels of many common drugs, including ciprofloxacin (Cipro), carbamazepine (Tegretol, Equetro), and fluoxetine (Prozac).

While working at EPA Dr David Lewis published evidence that teenager Shayne Conner (of New Hampshire) died and other neighbors were harmed from living near land applied with sewage sludge (Lewis et al 2002). He furthermore became involved after dairy herds of two […]
