What Are Biosolids?

“Biosolids” is the word waste treatment industry marketers came up with to rebrand sewage sludge, the solid byproduct of wastewater treatment processes. The reason the industry needed to rebrand sewage sludge was because they planned on marketing and selling the nutrient-rich waste to farmers and home gardeners as cheap fertilizer and compost products.

But biosolids aren’t just rich in nutrients. Biosolids can contain high levels of toxic PFAS “Forever Chemicals” (perfluoroalkyl and polyfluoroalkyl substances) that aren’t removed during the waste treatment process. And neither are the phthalates, pesticides, PCBs, antibiotics and other pharmaceuticals, microplastics, heavy metals, and innumerable other harmful substances that have been found in biosolids.

Applications of biosolids contaminate the soil with toxic PFAS and other chemicals, which are then taken up by crops grown in that soil. PFAS also migrates to contaminate groundwater and surface waters. The meat, milk and eggs of livestock become contaminated when the animals consume adulterated crops and water.

The biosolids industry and the commercial fertilizer and compost companies that use biosolids continue to claim that the products are safe and non-toxic. Even municipalities have been giving out biosolids fertilizer and compost to farmers, community gardens, and home gardeners for free, without warning about the dangers.

Unfortunately, the Environmental Protection Agency (EPA), though aware of the problem, still allows the commercialization of toxic biosolids. Just as alarming, the U.S. Department of Agriculture (USDA) actively promotes the use of biosolids as fertilizer to commercial farmers. We suspect this is due to the revolving door and corporate capture of our regulatory agencies and the resulting collusion, favoring corporate profits over human or environmental health.

In 2022, Sally Brown, Research Professor at the University of Washington and veteran biosolids industry lobbyist, was selected by USDA Secretary Tom Vilsack to serve on USDA’s inaugural Advisory Committee for Urban Agriculture.

Sally Brown once called environmental activists “ecoterrorists” for a successful protest on March 4, 2010, that stopped the San Francisco Public Utilities Commission from giving away sewage sludge as “organic biosolids compost” for home and school gardens.

As you’ll soon read, it’s Sally Brown that is the ecoterrorist for promoting biosolids.

Biosolids Poisoning Farms and Farmers Across America

The practice of using biosolids as fertilizer on conventional farms has been happening for decades but has, more recently, turned into a national catastrophe, creating a crisis for farmers and ranchers across the country.

Although the use of biosolids as fertilizer is prohibited in organic agriculture, even organic farms have been hit hard.

March 22, 2022, The Guardian reported:

Maine organic farmers Johanna Davis and Adam Nordell bought Songbird Farm in 2014. By 2021 the young family with their three-year-old son were hitting their stride, Nordell said. But disaster struck in December. The couple learned the farm’s previous owner had decades earlier used PFAS-tainted sewage sludge, or “biosolids”, as fertilizer on Songbird’s fields. Testing revealed their soil, drinking water, irrigation water, crops, chickens and blood were contaminated with high levels of the toxic chemicals. The couple quickly recalled products, alerted customers, suspended their operation and have been left deeply fearful for their financial and physical wellbeing. “This has flipped everything about our lives on its head,” Nordell said. “We haven’t done a blood test on our kid yet and that’s the most terrifying part. It’s f#####g devastating.” Ironwood Organic Farm, about six miles from Songbird Farm, tested its water and found high levels suspected to have migrated from a neighbors’ sludge-packed field. The small produce farm pulled its products, halted operations and is nervously awaiting more test results. “I spent my entire adult life building this farm,” said Nell Finnigan. “Everything is at stake for us, and this is a tragedy for anyone who comes up with a high [groundwater] well test.” Stoneridge Farm, a small dairy operation more than 100 miles south of Songbird Farm, discovered in 2016 that sludge and paper mill waste used as fertilizer had probably contaminated its cows and milk. Stoneridge killed most of its livestock in 2019. Co-owner Fred Stone was denied federal assistance for his tainted milk because one of its milk tests came in just below the state’s limit, but Stone didn’t feel comfortable selling it. Now his family of four, which believes PFAS is behind their health ailments from thyroid disease to reproductive problems, survives on welfare and friends’ and family’s generosity. Stone said he could have continued to sell contaminated food: “This is the cost of having a moral compass and doing the right thing.” “I don’t know how we are going to get debts paid,” he added. “I don’t know how the Christ we are going to live. I don’t know how we’re going to survive.”

...

March 11, 2024, KCUR reported:

“This is a hundred-year-old operation,” Jason Grostic said. “My grandpa milked cows, my dad milked cows, I milked cows, (then) got into the beef industry. It’s in my blood.” But Grostic may be at the end of the line. Two years ago, he was blindsided when the state of Michigan ordered him to shut down his farm, citing high levels of PFAS in both his beef and soil. Grostic had been using biosolids, a treated byproduct from wastewater plants, to fertilize his crops, which he then fed his cattle. But what he thought was a cost-effective fertilizer, turned out to be laden with PFAS. It’s a risk, Grostic said, no one warned him about — and now his 400-acre farm has been deemed unusable. “I took a fertilizer source that was recommended and was EPA-approved, and the government dropped the ball by not testing it and assuring it was a clean product,” he said.

We encourage you to watch the VICE Special Report, “The Hidden Chemicals Destroying American Farms,” a year long investigation featuring Jason Grostic and his experience with biosolids and PFAS. It will shock you.

[turtlesandfrogs]

Started the day by reading this article from the NY times, and I'm frankly, disturbed.

Some highlights:

"For decades, farmers across America have been encouraged by the federal government to spread municipal sewage on millions of acres of farmland as fertilizer. It was rich in nutrients, and it helped keep the sludge out of landfills."

Which I knew, and I knew that there were concerns about contaminants from like, the medications people were on. But human waste is part of the nutrient cycle, and it always made sense to me that it should be throughly composted and returned to agricultural lands, and I assumed that people in general were taking the steps necessary to make it safe.

But here's what I didn't know:

"The 1972 Clean Water Act had required industrial plants to start sending their wastewater to treatment plants instead of releasing it into rivers and streams, which was a win for the environment but also produced vast new quantities of sludge that had to go somewhere."

Which, yay, no longer polluting bodies of water, but now that means we're applying industrial waste water to agricultural lands. And have been since 1972. Which leads to this situation, among many others, I'm sure:

"The sludge that allegedly contaminated the Colemans’ farm came from the City of Fort Worth water district, which treats sewage from more than 1.2 million people, city records show. Its facility also accepts effluent from industries including aerospace, defense, oil and gas, and auto manufacturing. Synagro takes the sludge and treats it (though not for PFAS, as it’s not required by law) then distributes it as fertilizer."

So here's what some states are doing:

"In Michigan, among the first states to investigate the chemicals in sludge fertilizer, officials shut down one farm where tests found particularly high concentrations in the soil and in cattle that grazed on the land. This year, the state prohibited the property from ever again being used for agriculture. Michigan hasn’t conducted widespread testing at other farms, partly out of concern for the economic effects on its agriculture industry.

In 2022, Maine banned the use of sewage sludge on agricultural fields. It was the first state to do so and is the only state to systematically test farms for the chemicals. Investigators have found contamination on at least 68 of the more than 100 farms checked so far, with some 1,000 sites still to be tested.

“Investigating PFAS is like opening Pandora’s box,” said Nancy McBrady, deputy commissioner of Maine’s Department of Agriculture."

This is fun:

"The E.P.A. is currently studying the risks posed by PFAS in sludge fertilizer (which the industry calls biosolids) to determine if new rules are necessary.

The agency continues to promote its use on cropland, though elsewhere it has started to take action. In April, it ordered utilities to slash PFAS levels in drinking water to near zero and designated two types of the chemical as hazardous substances that must be cleaned up by polluters. The agency now says there is no safe level of PFAS for humans...

It’s difficult to know how much fertilizer sludge is used nationwide, and E.P.A. data is incomplete. The fertilizer industry says more than 2 million dry tons were used on 4.6 million acres of farmland in 2018. And it estimates that farmers have obtained permits to use sewage sludge on nearly 70 million acres, or about a fifth of all U.S. agricultural land."

There's more, but I wanted to condense it at least a little bit. I am glad we're raising awareness, and I'm glad we're starting to regular the amount in our drinking water, and I hope that we'll find a way to actually deal with PFAS. I am so frustrated that people are exposed in the first place, and in nigh inescapable ways.

Also, to all those people who were like, oh, organic isn't at all healthier for consumers? Guess what the organic standards don't allow to be applied?

Their Fertilizer Poisons Farmland. Now, They Want Protection From Lawsuits. (New York Times)

Excerpt from this story from the New York Times:

For decades, a little-known company now owned by a Goldman Sachs fund has been making millions of dollars from the unlikely dregs of American life: sewage sludge.

The company, Synagro, sells farmers treated sludge from factories and homes to use as fertilizer. But that fertilizer, also known as biosolids, can contain harmful “forever chemicals” known as PFAS linked to serious health problems including cancer and birth defects.

Farmers are starting to find the chemicals contaminating their land, water, crops and livestock. Just this year, two common types of PFAS were declared hazardous substances by the Environmental Protection Agency under the Superfund law.

Now, Synagro is part of a major effort to lobby Congress to limit the ability of farmers and others to sue to clean up fields polluted by the sludge fertilizer, according to lobbying records and interviews with people familiar with the strategy. The chairman of one of the lobbying groups is Synagro’s chief executive.

In a letter to the Senate Committee on Environment and Public Works in March, sludge-industry lobbyists argued that they shouldn’t be held liable because the chemicals were already in the sludge before they received it and made it into fertilizer.

The lobbying has found early success. A bill introduced by Senators John Boozman of Arkansas and Cynthia Lummis of Wyoming, both Republicans, would protect sludge companies like Synagro, as well as the wastewater plants that provide the sludge, from lawsuits. A House bill has also been introduced.

Ms. Lummis will “work with President Trump’s E.P.A. to ensure ‘passive receivers,’ like water utilities and others, are protected from bogus third-party lawsuits,” her office said in a statement, referring to the Environmental Protection Agency.

Synagro and Goldman Sachs declined to answer detailed questions. Synagro in its most recent sustainability report acknowledged the risks of PFAS contamination in its fertilizer, calling it “one of our industry’s challenges.”

Widespread manufacturing of PFAS began decades ago, with some of the country’s largest chemical companies making vast quantities and downplaying the risks. Water-resistant and virtually indestructible, the chemicals have been used in everything from nonstick pans and dental floss to firefighting gear and waterproof clothing.

How Sewage Treatment Plants Contribute to Environmental Protection

Sewage treatment plants (STPs) play a vital role in safeguarding the environment and public health by managing wastewater effectively. As urban populations grow and industrialization continues to expand, the need for efficient wastewater management becomes increasingly important. Sewage treatment plants not only treat domestic and industrial waste but also contribute significantly to environmental protection. In this article, we explore how these plants help protect the environment and support sustainability.

1. Preventing Water Pollution

One of the primary functions of sewage treatment plants is to prevent untreated sewage from entering rivers, lakes, and oceans. Without treatment, sewage contains harmful pathogens, chemicals, and nutrients that can degrade water quality and harm aquatic ecosystems. Untreated wastewater, when discharged into water bodies, can lead to the spread of waterborne diseases and the eutrophication of lakes and rivers, causing oxygen depletion and killing marine life.

Sewage treatment plants remove contaminants from wastewater through physical, chemical, and biological processes. This process significantly reduces the levels of harmful substances like bacteria, viruses, and excess nutrients, ensuring that the water released back into the environment is clean and safe for aquatic life and humans.

2. Reducing Greenhouse Gas Emissions

Sewage treatment plants contribute to the reduction of greenhouse gas emissions in several ways. First, by treating and managing wastewater effectively, these plants reduce the need for landfills, where untreated waste can release methane, a potent greenhouse gas. By diverting sewage from landfills and treating it properly, STPs help mitigate the environmental impact of waste disposal.

Additionally, many modern sewage treatment plants incorporate advanced technologies, such as biogas production from organic waste. The biogas generated during the treatment process can be captured and used as a renewable energy source, reducing reliance on fossil fuels and contributing to cleaner energy production.

3. Promoting Water Conservation and Reuse

Water is a precious resource, and with the increasing demand for fresh water, it is essential to make the most of every drop. Sewage treatment plants contribute to water conservation by treating and recycling wastewater for reuse. The treated water, also known as effluent, can be used for a variety of non-potable purposes such as irrigation, industrial processes, and even landscaping.

This recycling process reduces the pressure on freshwater resources, especially in areas that face water scarcity. In some regions, advanced sewage treatment plants even produce high-quality treated water that can be used for drinking, thus helping to close the water loop and reduce the demand for fresh water from natural sources.

4. Protecting Soil and Agricultural Land

Sewage treatment plants also contribute to environmental protection by providing a safe and effective method for managing sewage sludge, a byproduct of the treatment process. Sewage sludge contains organic matter that can be used as a natural fertilizer or soil conditioner. After treatment, the sludge is often processed and converted into biosolids, which can be safely applied to agricultural land to improve soil quality and promote plant growth.

By recycling sludge into valuable agricultural products, sewage treatment plants reduce the need for chemical fertilizers, which can have harmful environmental impacts, such as contaminating groundwater and affecting biodiversity. This sustainable use of treated sludge supports soil health and reduces the environmental footprint of farming.

5. Mitigating the Impact of Industrial Waste

Sewage treatment plants play a crucial role in treating not only domestic waste but also industrial effluents. Many industries discharge pollutants such as heavy metals, chemicals, and toxic substances into the wastewater system. Without treatment, these contaminants can pose serious risks to the environment, wildlife, and human health.

Sewage treatment plants equipped with advanced treatment technologies, such as chemical precipitation, filtration, and activated carbon adsorption, can effectively remove industrial pollutants from wastewater before it is released into the environment. This ensures that industrial effluents are treated to meet environmental standards and that harmful substances are not released into rivers, lakes, or the atmosphere.

6. Supporting Biodiversity and Ecosystem Health

By preventing the release of untreated sewage into natural water bodies, sewage treatment plants help maintain healthy ecosystems and biodiversity. Clean water is essential for the survival of aquatic species, and by reducing pollution, STPs ensure that aquatic habitats remain conducive to life.

Moreover, many sewage treatment plants are designed to include wetland systems or artificial lagoons that provide additional filtration and habitat for wildlife. These systems not only improve water quality but also create environments that support plant and animal life, contributing to biodiversity conservation.

7. Complying with Environmental Regulations

Sewage treatment plants are regulated by environmental laws and standards that aim to protect natural resources and ensure that wastewater is treated to meet specific quality criteria. By adhering to these regulations, STPs help prevent environmental degradation and promote sustainable development.

Governments around the world have established stringent wastewater treatment standards to protect water bodies from contamination and to safeguard public health. Sewage treatment plants that comply with these regulations play a crucial role in meeting these standards and maintaining the integrity of local ecosystems.

8. Raising Public Awareness and Engagement

Sewage treatment plants also serve as important tools for raising public awareness about the importance of water conservation, waste management, and environmental protection. Many STPs offer educational programs and tours that help the public understand the significance of proper wastewater treatment and the environmental benefits of reducing water pollution.

By educating the community, sewage treatment plants encourage individuals and businesses to adopt more sustainable practices, such as reducing water usage, recycling, and avoiding the disposal of harmful substances down the drain. This collective effort contributes to a cleaner, healthier environment.

Conclusion

Sewage treatment plants are essential to environmental protection, as they prevent pollution, conserve water, and support sustainable land use practices. By treating wastewater effectively, these plants contribute to cleaner rivers, lakes, and oceans, promote the reuse of water, and protect ecosystems from harmful contaminants. Furthermore, they help reduce greenhouse gas emissions and provide valuable resources such as biogas and biosolids for energy production and agriculture. As urban populations grow and environmental challenges intensify, the role of sewage treatment plants in protecting the environment will continue to be crucial in ensuring a sustainable future for generations to come.

Reducing Environmental Risks from Sewage Treatment Plant Effluent

Sewage Treatment Plant (STP) effluent, although treated to remove contaminants, can still pose significant environmental risks if not managed properly. These risks primarily stem from residual pollutants such as nutrients, pathogens, heavy metals, and microplastics that may remain in the effluent after treatment. These pollutants can harm aquatic ecosystems, degrade water quality, and negatively impact public health. To reduce these risks, it is essential to adopt best practices, advanced technologies, and proactive management strategies in the treatment, monitoring, and disposal of STP effluent.

1. Advanced Treatment Technologies for Improved Effluent Quality

One of the most effective ways to reduce environmental risks from STP effluent is to improve the quality of treatment processes.

Tertiary Treatment: After primary and secondary treatment, tertiary treatment can further refine effluent quality by removing remaining pollutants, particularly nutrients like nitrogen and phosphorus. Technologies such as membrane filtration, reverse osmosis, and UV disinfection can provide high-quality effluent that meets stringent environmental standards.

Nutrient Removal: Nitrogen and phosphorus are common in STP effluent and can lead to eutrophication in water bodies, resulting in harmful algal blooms and oxygen depletion. Advanced nutrient removal technologies, such as biological nutrient removal (BNR), can significantly reduce these pollutants in effluent, mitigating the risk of water body degradation.

2. Effluent Quality Monitoring and Compliance

Continuous monitoring and adherence to environmental regulations are essential in minimizing the environmental impact of STP effluent. Regular monitoring ensures that any residual pollutants are detected and managed effectively.

Real-Time Monitoring: Implementing sensors and automated monitoring systems in STPs can provide real-time data on various parameters like pH, dissolved oxygen, nutrient levels, and microbial contamination. This allows for early detection of any changes in effluent quality and enables quick corrective action.

Regulatory Compliance: Adhering to local and international water quality standards for effluent discharge is crucial. STPs should regularly assess their compliance with regulations governing the discharge of treated wastewater into natural water bodies, ensuring that they do not exceed permissible pollutant levels.

3. Sludge Management and Resource Recovery

Sludge produced during sewage treatment contains concentrated contaminants and must be managed properly to avoid further environmental risks. Efficient sludge management reduces the likelihood of pollutants leaching into the environment.

Sludge Treatment: Techniques such as anaerobic digestion, dewatering, and composting can help reduce the volume of sludge, stabilize it, and eliminate harmful pathogens. These treatments make sludge safer for disposal or reuse.

Resource Recovery: Treated sludge can be converted into biosolids, which can be used as fertilizers in agriculture, reducing the need for synthetic fertilizers. Additionally, biogas produced during anaerobic digestion can be harnessed as a renewable energy source, promoting a circular economy.

4. Minimizing Microplastic Contamination

Microplastics are a growing concern in STP effluent due to their persistence in the environment and harmful effects on aquatic life. While microplastics are difficult to remove entirely, there are strategies that can minimize their presence in treated effluent.

Advanced Filtration: Implementing advanced filtration systems, such as micro-screens and membrane filters, can help capture microplastics during the treatment process. These systems can filter out fine particles, reducing the concentration of microplastics in effluent.

Source Control: Addressing the root cause of microplastic contamination involves promoting better waste management practices, reducing plastic usage, and encouraging industries to adopt more sustainable practices to prevent plastics from entering the sewage system in the first place.

5. Ecological Risk Assessment and Adaptive Management

To understand and mitigate the environmental risks of STP effluent, it is important to assess the potential ecological impact of pollutants on aquatic ecosystems.

Ecological Risk Assessment: Conducting detailed studies of the impact of STP effluent on local ecosystems, including aquatic life and water quality, helps identify specific risks. This may include assessing the effects of residual chemicals, nutrients, and pathogens on biodiversity and ecosystem health.

Adaptive Management: The adoption of an adaptive management approach allows STPs to adjust treatment processes based on monitoring results and ongoing research. By staying flexible and responsive to emerging environmental challenges, STPs can continuously improve their effluent management practices.

6. Effluent Reuse and Circular Water Management

Reusing treated effluent for non-potable applications not only conserves freshwater resources but also reduces the environmental risks associated with effluent discharge. Properly treated effluent can be safely used for agricultural irrigation, industrial processes, landscape irrigation, and cooling water systems.

Agricultural Irrigation: Using STP effluent for irrigation can provide a valuable resource, especially in water-scarce regions. However, the effluent must be treated to remove pathogens and ensure that the nutrients it contains do not cause harm to soil health or water bodies downstream.

Industrial and Municipal Reuse: Effluent can be used in cooling systems, for flushing toilets, or for landscape irrigation, significantly reducing the need for potable water and minimizing the discharge of untreated wastewater into natural water bodies.

7. Green Infrastructure for Natural Treatment

Green infrastructure solutions can complement traditional sewage treatment methods and provide additional environmental benefits.

Constructed Wetlands: These artificial wetlands use plants and natural processes to further treat effluent, removing nutrients, heavy metals, and pathogens. Constructed wetlands also provide habitat for wildlife, improving biodiversity and contributing to ecosystem services.

Riparian Buffers: Planting vegetation around water bodies and discharge points helps filter out pollutants from effluent before they reach natural water systems, reducing the risk of water quality degradation and improving habitat for aquatic organisms.

8. Public Education and Stakeholder Engagement

Engaging with the public, industries, and other stakeholders is essential in reducing the environmental risks associated with STP effluent. Raising awareness about the importance of wastewater treatment, pollution prevention, and sustainable water management practices fosters a collective responsibility for protecting water quality.

Community Engagement: Educating the public on the importance of proper waste disposal, water conservation, and reducing plastic use can help reduce the load on STPs and improve effluent quality.

Industry Collaboration: Collaborating with industries that discharge wastewater into the sewage system can help reduce pollutant levels and optimize treatment processes, ultimately minimizing the environmental impact of effluent.

Conclusion

Reducing environmental risks from Sewage Treatment Plant effluent requires a multi-faceted approach, combining advanced treatment technologies, continuous monitoring, effective sludge management, and sustainable practices. By adopting best practices in effluent treatment, reuse, and disposal, STPs can significantly reduce the adverse impact of wastewater on aquatic ecosystems, human health, and the environment. With the right technologies, regulatory compliance, and community engagement, the safe management of STP effluent is achievable, contributing to cleaner water bodies and a more sustainable future.
