Sewage treatment plants were never designed to produce fertilizer. What is being spread on farmlands now and called biosolids or free fertilizer is the concentrated residuals of whatever comes into the sewage treatment plant from all sources: homes, businesses, industry, hospitals, laboratories, nursing homes, funeral homes, and street run-off. This thick viscous concentrated residual called sludge is what remains after the sewage water is treated to be discharged back into rivers or streams.
We are told that sewage sludge/biosolids are recycled organic human waste, which is true. What is not told is that from 80 to 100,000 chemicals are used in products for personal and home use, in industry, and medical and laboratory facilities. Any drugs or chemicals going down the drain into the sewer system may wind up on the land intact or as chemical mixtures never anticipated or tested for toxicity. The treated sludge also contains bacteria, viruses and intestinal worms and parasites. Class B sewage sludge can have 2 million fecal coliform indicator bacteria (thermotolerant E. coli) per gram (size of a sugar cube) which means there’s pathogenic bacteria in the sludge—but not what type or amount and this will be sprayed or spread on farm fields which will grow human and animal crops and grass for cattle. The waste water treatment plant has to follow EPA and state regulations for processing sewage sludge but this process does not remove the drugs, chemicals, toxic metals, or all of the bacteria, viruses, or parasites.
