Please educate yourselves with peer-reviewed, published data from scientists who have spent their lives researching biosolids. The "so-called" experts that you are citing do not have any objective evidence of harm from land-applying Class A biosolids according to increasingly stringent regulations in many states and provinces.
Land application of sewage sludge at agronomic rates diverts organic waste from landfills, returns nutrients and organic matter to the soil, and reduces greenhouse gas emissions. Biosolids do contain small amounts of pharmaceuticals and other industrial products. Many of these industrial chemicals (such as phthalates and flame retardants) are in MUCH higher concentrations in your house dust and on consumer products, and you are MUCH more likely to come in direct contact with these items. In addition, soil is the most efficient and appropriate medium for degrading these materials over time. Land application of Class A materials and ongoing monitoring is the best way to manage these materials.
Again, I urge the public to educate themselves. Presence DOES NOT equal risk. Risk is a combination of presence, concentration and likelihood of exposure.
If you want to read some evidence-based science about biosolids use in agriculture, please go to Google Scholar and search papers by Dr. Gordon Price, Dr. Chris Metcalfe, Dr. Paul Sibley, Dr. Lynda McCarthy, Dr. Sally Brown, Dr. George O'Connor. These distinguished professors have spent their careers studying the use of biosolids and the possible environmental and human health risks of their use in agriculture. Do not listen to the fearmongering of those who have not done any primary research of their own in this area.
How much is used and how often ?.? I know it's used on golf courses, but then again how much and how often?
We can't allow PCBs, dioxins and other chlorine and fluorine-based chemicals to be created IN THE FIRST PLACE. Leave the heavy metals in the ground where they belong and STOP the horrendous production of chlorine and petroleum chemicals poisoning and killing everything on earth. They have no inherent "right" to exist. Just the opposite. Then we don't have to worry about getting rid of toxic sludge. There is no way to get rid of these persistent manmade poisons--especially with environment-hating greed-mongers creating, and digging up, more everyday.
What are the alternatives suggested for getting rid of this solid waste?
"Keep sewage sludge out of life cycles" -- this is a ridiculous, mindless "solution" to anything! In this Nature we interactively and interdependently occupy, there is no such thing as "waste," and no place isolated from Life. Within the context of that self-evident truth, we must make our sewage sludge, and everything else we produce, nurturing to the biodiverse ecology we inhabit. Ceasing to consume (or throw away) non-biodegradable substances will be a first step ....
Laura Orlando's article is a bright light in the darkness of misinformation, and propaganda regarding this ill-conceived practice of disposing a municipalities' concentrated toxic sewage sludge on farm and forestland, that results in poisoned air, water, food, and illness. Thank you!
Laura Orlando hit the nail right on the head. I would add this information to hers concerning the chemicals in this mess:
1. EPA's 40 CFR 261.30(d) and 261.33 (4), every US industry connected to a sewer can discharge any amount of hazardous and acute hazardous waste into sewage treatment plants. There are over 80,000 chemicals in commerce and growing even today.2. EPA's Office of Inspector General's Report (OIG) No. 14-P-0363 is the final RED flag on the ill-conceived practice of land application of industrial, medical, storm and household waste. Just Google this EPA OIG number to see that industrial pre-treatment has not worked and is not working.3. Sewage sludge and biosolids are over burdened with phosphate which is thecause of algae blooms
