Land application of sewage biosolids for crop production as designed by the Ontario Government

For full text and tables see:  http://www.esemag.ca/0901/land.html

I wonder where the reports are or if they even exist to show that complete tests have been conducted on the hundreds of thousands of metric tonnes of sewage sludge spread on Canadian and American farm land each and every year.

Why don’t I feel better when I read this data??? Apples, grapes etc can have sewage sludge spread as recently as 3 months before harvest. OMG.

Did you know that the feed fed to the cows and other hay/ silage fed animals are the very happy recipients of biosolids?? And the pasture land the animals graze on may have toxic biosolids applied 2 months before grazing?

Did you know that the sod from the commercial sod farm which was laid on your lawn which your children and pets have been rolling around on are also treated to biosolid application??? But it isn’t suggested for home lawns and gardens.

This post is a work in progress and as I unearth more statistics I will add them to this post.

The maximum depth of a fluid sewage biosolid that can be surface applied at any one time is 1.3 cm. This depth is equivalent to an application rate of 130 m3/ha. from an article by M Payne of Omafra (Ont Govt) Environmental Science & Engineering – www.esemag.com – September 2001

If a single application of fluid biosolids is to be limited to 1.3cm you can see why such vast areas of land are being contaminated. It sure begs the question How precise are these contractors in their application????

Ontario- Ottawa

BIOSOLIDS UTILIZATION PROGRAM STATUS UPDATE From 1997 to 2000, over 53,548 wet tons of biosolids have been successfully land applied to farms in and around the Region of Ottawa-Carleton on over 2,117 hectares of land.

Ontario- Toronto using farms in

These include all agricultural land within an area bounded by Hamilton, Brant, Waterloo, Perth and Bruce on the west, Grey,Simcoe, and Muskoka on the north and Peterborough, Hastings and Prince EdwardCounties on the east. Using the three inventory methods, the following results
were obtained for this area:
♦ Based on Method 1, this land area has the capacity to accept
approximately 17,000 tonnes of dry biosolids per year (17,000 t ds/y);
♦ Based on Method 2, this land area has the capacity to accept
approximately 26,000 t ds/y; and,
♦ Based on Method 3, this land area has the capacity to accept
approximately 133,000 t ds/y.
These figures can be compared to the Toronto biosolids generation rate of 63,000
t ds/y, of which 50,000 t ds/y is currently intended for beneficial reuse such as
agricultural land application as biosolids cake or thermally dried pellets. When application is limited by soil nutrient requirements (Method 1),
phosphorus is the limiting nutrient, and there are 22 Counties or Regions,out of 48 in total for the province, that have no additional capacity for
biosolids once manure application is taken into account.

Whatever you call it, the province’s municipalities produce a lot of it: 914,726 tonnes of sludge was scraped out of 700 water treatment plants in Quebec in 2007, the most recent year for which these statistics are available.

About 42 per cent of the sludge was incinerated and 31 per cent was sent to dumps. But the remaining 27 per cent was “recycled” as fertilizer, mostly on farmland.

That’s 246,976 tonnes, can you picture an area

1000 metres long by 1000 metres wide by 1000 metres deep?

its hard to visualize that much shit & chemical toxins I know.

– if you get in your car and drive 1 kilometer turn at right angles drive another kilometer, turn again at a right angle drive another kilometer back to your starting point and look up in the sky 1 kilometer that’s almost how much toxic sludge was applied to Quebec farms in 2007.

The Wrong Kind of ‘Organic’ Farming: Biosolids
In rural areas, properties adjacent to farmland fertilized with biosolids have suffered dramatic reductions in property value and lowered saleability. PJ Wade cautions rural real estate buyers to be alert to sewage sludge applications or they may lose their home like one family recently has.

Please whatever you do even if you never read anything else I write, please read about Sewage Sludge A.K.A. biosolids. What are biosolids? If you want to believe the government, any government ((at all levels) Canadian, American, UK, Australian…. it doesn’t really matter)) propaganda biosolids are “nutrient rich organic material produced by treating wastewater solids.”  What biosolids really are is sewage sludge produced from wastewater containing a combination of industrial, commercial, hospital, and household contaminants that is routed through municipal sewage treatment plants. The U.S. EPA’s most recent Sewage Sludge Survey (January 2009) Briefly, the survey found that:

  • Nitrite/nitrate, fluoride and water-extractable phosphorus were found in every sample.
  • 27 metals were found in virtually every sample, with one metal (antimony) found in no less than 72 samples.
  • Of the six semivolatile organics and polycyclic aromatic hydrocarbons, four were found in at least 72 samples, one was found in 63 samples, and one was found in 39 samples.
  • Of the 72 pharmaceuticals, three (i.e., cyprofloxacin, diphenhydramine, and triclocarban) were found in all 84 samples and nine were found in at least 80 of the samples. However, 15 pharmaceuticals were not found in any sample and 29 were found in fewer than three samples.
  • Of the 25 steroids and hormones, three steroids (i.e., campesterol, cholestanol, and coprostanol) were found in all 84 samples and six steroids were found in at least 80 of the samples. One hormone (i.e., 17a-ethynyl estradiol) was not found in any sample and five hormones were found in fewer than six samples.
  • All of the flame retardants except one (BDE-138) were found in nearly every sample; BDE-138 was found in 56 out of 84 samples.

Serious health problems have been directly linked to the land application of sewage sludge, sludge that is no different than that which the your town or city is giving away to the people. . Rarely, if ever has the public been sold such a huge lie. The truth is, that what to do with wastewater solids is such a huge problem the whole world over that there is tacit agreement to keep all policy discussions couched in such deceptive language that red flags won’t pop up for the average Joe. I am not an intellectual snob by any means, I am not dissing anyone; I know as a 50-year-old woman who until recently worked long hours & couldn’t conceive of spending time after taking care of job and family to spend hours reading about issues such as sewage sludge. It is hard I know as a working Mom or Dad to be involved & engaged in environmental issues. My hat goes off to those who are able to make a commitment to socially and environmentally relevant issues. My work was environmentally significant therefore my contribution was made. How naïve I was!!! I could kick myself now for leaving it up to others to carry the torch for those things I consider important. Family, health, job are all dependant on a habitable planet. Watch this space for more info on biosolid/ sewage sludge.
