A recent story came out in the popular press about the heavy metals lead and cadmium being found in certain dark chocolate products. As this article points out, one of the ways these heavy metals enter our food supply is via sewage sludge applied on land as so-called 'fertilizer' where food is grown for human consumption. Here, read it yourself: What are the sources of lead and cadmium?

Sludge Tracker unveils the inept practices of toxic waste disposal by agencies and industry, as seen through the eyes and experiences of citizens and activists. This seminal work reveals the dangerous and destructive consequences of land-disposed Toxic Sewage Sludge, while shining a light forward on how we can build a healthier, more vibrant future.
Land-disposed Toxic Sewage Sludge, water-disposed wastewater effluents, and the land or water disposal of other toxic wastes, such as leachates from landfills, provoke a broad spectrum of adverse impacts on human and environmental health, noting well that nearly all chronic diseases are incited by long-term exposure to low levels of environmental contaminants and pollutants.
Our mismanaged wastes contribute to the global crisis of climate change, and to pollution of our air, food, soil, and water, leading to famine, drought, compromised health, epidemics, deforestation, and lost biodiversity. No matter the source, kind or concentration of toxics in our wastes, whether in sludges from wastewater treatment plants, wastewater effluents, stormwater runoff, landfill leachates, industrial or medical wastes, or agriculture runoff that may include fertilizers, pesticides or wastes from concentrated animal feeding operations, the net result is environmental degradation. The consequences include a decline in readily available potable water supplies, aggravated further by climate change and population growth.
It’s all about the reluctance of agencies to safely manage our produced, released, and ever-accumulating wastes, and it’s about water—good, clean, potable water. Earth is a planet with surface water, and it resides at a steady state, meaning there will never be more or less water than we have now, and it’s often in the wrong form or place. We need potable water for survival, yet today, nearly half the world’s population is adversely affected by a shortage of fresh water, and such predicament incites disease, famine, food insecurity, wildfire, human migration, and war. Therefore, we must notice that it’s all about the ready availability of clean water for the safeguarding of human and environmental health, which current infrastructure fails to do.
We can act by protecting our air, food, soil, and water from contamination and pollution, or we can bear witness to an alarming decline of our life-sustaining resources. The climate is changing and the population is increasing, while we continue to contaminate and deplete our critical fresh waters, never seeking alternatives or improvements for proper management of our growing toxic wastes. Protecting our essential resources is critical to human survival. Workable solutions exist to convert toxic wastes to renewable clean energy and beneficial byproducts—a climate crisis no longer.
A new study has found that fertilizer made from sewage sludge and used widely in agriculture operations is introducing vast amounts of microplastics into Europe's soils
The sludge that is created through sewage treatment processes is rich in nutrients like phosphorous and nitrogen, making it an excellent source of fertilizer for agriculture. But not all that it contains is good for the environment, with a new study demonstrating how the material acts as a vehicle for huge amounts of tiny plastic fragments to enter soils, so much so the authors suggest Europe's farms could be acting as the world's largest reservoir for microplastics pollution.
Sewage sludge serves as an appealing and sustainable source of fertilizer, for both large-scale agriculture operations and home gardeners. But studies are starting to illustrate that its contents may not be entirely benign, neither for the environment or living organisms.
A study published last year that analyzed home fertilizer products found unsafe levels of toxic PFAS "forever chemicals" in every sample. That research found that typical sewage treatment methods don't break down these persistent chemicals, and as sludge is widely applied to lands across the US, it introduces huge amounts of them to food crops and waterways.
This new study was carried out by scientists at Cardiff University and the University of Manchester and focused on the farmlands of Europe, and the risks posed to them by fertilizers made from sewage sludge. The work involved analyzing samples from a wastewater plant in Newport, South Wales, which treats sewage from a population of around 300,000.
This showed that the plant was collecting larger plastic particles between 1 and 5 mm in size with a 100-percent strike rate, preventing them from slipping through into the waterways. Each gram of the sewage sludge created through this process, however, was then found to contain up to 24 microplastic particles, amounting to around one percent of its total weight.

Excerpt from the article in NC Policy Watch:
"Traditional wastewater treatment methods can’t remove PFAS, so the compounds enter the waterways – the Haw River, the Cape Fear – unimpeded. Sludge, also known as biosolids, from wastewater treatment plants is often applied as fertilizer on agricultural fields. From there, PFAS can seep into the groundwater or run off into rivers and streams, and ultimately the drinking water supply."
An early view of the Synagro waste-pit blaze
June 1, 2022: The early view of an inferno in the guts of an 80-acre High Desert pit of feces, brewery muck and more from across Southern California.
San Bernardino County’s composting regulator may force Synagro Technologies Inc. to stop accepting all forms of waste at its open-air pit of sewage sludge in Hinkley after a more than three-month fire that’s now central to two “mass action” lawsuits by rural High Desert residents.
The county’s Environmental Health Services Division issued a cease-and-desist order with the potential for new fines against Synagro, a Maryland firm owned by a private-equity arm of Goldman Sachs Group Inc., in a Sept. 29 letter signed by EHS inspector Sarah Cunningham.
