Is it really safe to use biosolids aka sewage sludge on farmland and forests?

David Tenenbaum says "Yes!" in this popular 1997 journal article that consistently rank high in the biosolids Google search. The title is one of my all time favorites, The Beauty of Biosolids.

Even the picture of bubbling sewage with the title watermarked on it reflects the stark contrast between the first mental and visual "Yuck" impression , and the long list of environmental benefits that biosolids the resource bring from and back to society.

Biosolids Demonstration Garden - Sustainability via Sewage Sludge - Decades of safety and performance! #Free poster

King County is an inspiration leader for the rest of us who recognize how wonderful biosolids are. The information below is found on their website: http://www.kingcounty.gov/environment/wtd/Education/RWBGarden.aspx

 


Reclaimed water & biosolids demonstration garden

The research and demonstration garden at South Treatment Plant helps showcase beneficial use of our wastewater resources


Background
King County has been producing Class A reclaimed water since 1997 and exceptional quality biosolids compost since 1976. At our treatment plants, we are constantly recycling important resources that enhance our ability to conserve fresh water, save energy, reduce runoff pollution, and decrease effluent into our water bodies.

Research Garden

University of Washington researchers have worked with us for over three decades to evaluate effectiveness and safety of our resources. The reclaimed water and biosolids garden at South Treatment Plant was created in 2009, offering an opportunity to continue greenhouse research that began in 2008. In September of 2009, we held a luncheon where the results of the research were shared with potential customers and interested parties while they sampled food grown in the garden. The garden also won the Northwest Biosolids Management Association's 'Golden Gourd award' [external link] award in 2009. A second luncheon in 2010 focused on how to use compost in community gardens.


Also on this fabulous website is this very cool poster of the demonstration garden. I love their key messages:
  • Creating Resources from Wastewater
  • Local, Safe, and Sustainable
  • Don't take our word for it; the science is behind it
  • Making the World a Better Place one Garden at a time! Biosolids compost is a good fertilizer, soil conditioner, and also helps sequester carbon and reduce greenhouse gases!




Thank you, King County Biosolids folks! Keep up the Great work!!!
