The Soil Association urges use of sewage fertiliser on land

THE country's leading organic organisation has called for human sewage to be used on farmland as a fertiliser.

It is a shame that The Soil Association does not look further into the experiences of the use of sewage sludge in the US.

Sewage sludge is the necessarily hazardous by-product of the treating of wastewater by the Water Companies and the big problem is what to do with it.

Wastewater brings to sewage treatment plants all the wastes sent into the sewers from drains and toilets: industrial wastes, hospital wastes, commercial wastes, “human waste”, stormwater runoff, and every other kind of hazardous, toxic, and biological waste material produced in a municipality and carried away from its source via the sewer. Whatever toxins, hazardous materials, and other pollutants happen to be removed from the wastewater in the process of wastewater treatment, and that are concentrated in the sludge, will remain in the sludge. Nothing in the treatment of sewage “treats” e.g., detoxifies sludge. This is as true of the toxins - organic and inorganic - as it is of the pathogenic viruses and bacteria.

The word “Biosolids” is now being used a 'nice' word for sewage sludge by the water industry. It is a made up euphemism for sewage sludge that has no scientific basis. However, it has been adopted by the waste industry and the waste generators, and it can be found in place of the actual word, sludge, throughout their marketing materials and literature.

The Environmental Protection Agency has promoted the “land application” of sewage sludge in the US since 1993 as the preferred method for municipal sludge disposal. Millions of tons of hazardous sewage sludge have subsequently been spread on farmland, school yards, and parks in the United States, and many people living near sludged agricultural sites and many farm animals fed on sludged silage and hay have been made very sick.

In February 2008, the McElmurrays, diary farmers from Georgia, received an order and judgment issued by Federal Judge Anthony Alaimo of the 11th Circuit Court. The order addresses and confirms that there have been decades of deceit by the EPA and finds against the USDA and the EPA. It acknowledges that the sludge applications on the McElmurrays’ farm were responsible for killing hundreds of diary cattle and contaminating the milk supplies in several states. In the ruling, Judge Alaimo said, “Senior EPA officials took extraordinary steps to quash scientific dissent and any questioning of EPA’s biosolids program.” (United States District Court Southern District of Georgia, McElmurray v. U.S. Department of Agriculture, Case 1:05-cv-00159-AAAWLB Document 67, Filed 02/25/2008.)

In addition to toxic metals, pathogenic viruses and bacteria, hazardous materials in sludge include: endocrine disruptors like brominated flame retardants (PBDEs, which are a lot like PCBs), phthalates like DEHP (a reproductive and developmental toxin), persistent and toxic ingredients in personal care products (e.g., triclosan and galaxolide)hormones and pharmaceuticals.

A 2009 EPA study “Targeted National Sewage Sludge Survey” concluded that all sewage sludge contains toxic and hazardous materials, including large numbers of endocrine disruptors. For a list of peer-reviewed, technical papers documenting hazardous materials in sewage sludge, see http://www.sludgenews.org/resources/

The sole job of wastewater treatment is to reduce pollution in the effluent (the treated wastewater that leaves the plant): there is no treatment or “detoxification” of any hazardous or toxic material in the sludge.
It is claimed that some industrial wastewater discharges are “pretreated” before they go down the drain. Does “pretreatment” mean that none of the “pretreated” hazardous or toxic wastes go down the drain? - NO. “Pretreatment” means only that the concentrations of the limited number of hazardous materials covered by this program may have been lowered in the wastewater. The QUANTITY and TOXICITY of hazardous materials will remain unchanged. As anyone who has worked in the field of environmental protection for decades knows, the amount—not the concentrations—of hazardous or toxic material is the accurate measure of pollution in the environment.

DO WE REALLY WANT TO GO DOWN THE SAME ROAD?

  1. 'Humanure' is spread near where I live and the smell is absolutely horrendous. The stench travels for miles and no-one living within 'nose' distance can sell their houses.
    Spreading sewage sludge on land should be banned.

  2. The US Environmental Protection Agency (EPA) has identified infectious human and animal prions (think Mad Cow, Chronic Wasting Disease, Alzheimer's, Creutzfeld Jakob Disease, etc.) as emerging pathogenic contaminants of concern in sewage sludge "biosolids".:
    www.sludgevictims.com/prions/PRIONS-EPA-EMERGINGCONTAMINANTSINSLUDGEBIO.pdf

    Prions are found in the blood, urine and feces of human and animal prion victims.
    Dr. Adriano Aguzzi: "Further research by the team showed that, if inflammation is induced in any excretory organ of the body, prions are excreted in whatever substance the organ excretes.
    bacteriality.com/2008/05/05/prions/


    Alzheimer's Disease (AD) has been identified by scientists as a prion
    disease: www.sludgevictims.com/pathogens/ALZHEIMERS-CJD-samepriondisease.pdf

    There are 5.3 million victims of AD in the US who may be excreting infectious prions in their urine and feces to sewers, where the wastewater treatment process reconcentrates the prions in the sewage sludge: www.sludgevictims.com/pdf_files/PRIONSINSEWAGEANDSLUDGE_PEDERSEN_ETAL.pdf

    But the EPA and waste industry are making FALSE statements to the public. Even though they acknowledge there are prions in Class A sludge "biosolids" compost
    they still promote and advertise this contaminated waste for use in home flower and vegetable gardens, and parks, playgrounds, ballfields, where children with their hand-to-mouth behavior eat dirt and play as being "STERILE" and "PATHOGEN-FREE". www.sludgevictims.com/prions/PATHOGENFREECLASSASLUDGE.pdf

    University of Melbourne, October 2009 - The human prion is a hundred thousand times more difficult to deactivate than the animal form of infective agent: www.sciencealert.com.au/news/20091310-19987-2.html

    2007 - Dr. Joel Pedersen, et als: Oral transmissibility is enhanced by a common soil mineral which binds prions and can increase the infectious titer by a factor of 680. www.plospathogens.org/article/info:doi/10.1371/journal.ppat.0030093

    In the July 3, 2010 issue of VETERINARY RECORD, renowned Univ. of Wisconsin researcher Dr. Pedersen stated: “Finally, the disposal of sludge was considered to represent the greatest risk of spreading (prion) infectivity to other premises.”

  3. Well done to the 2 comments above.
    The trouble with the UK is that it does not look at the problems that others have had. We are too insular in our thinking - perhaps it is our 'Island mentality' but the 'GREENS' must look at the bigger picture before thet lead us to another disaster.

  4. This post is really interesting sewage treatment plants is important because to clear out up the sewage. Alfa India is providing the advanced and custom desired engineered systems and equipment for controlling water pollution and solid waste management. We are the leading Sewage treatment plants Manufacturer and Effluent Treatment plants Manufacturer
