PFAS: “Forever Chemicals,” Lawsuits, and the Damage to Soil, Livestock, and Human Health

Per- and polyfluoroalkyl substances, commonly known as PFAS, are among the most persistent and controversial pollutants of the modern industrial age. Often called “forever chemicals,” PFAS are a large group of synthetic compounds developed in the mid-20th century for use in products resistant to heat, water, grease, and stains. They have been used in nonstick cookware, waterproof clothing, firefighting foams, food packaging, industrial manufacturing, and countless consumer products. What once appeared to be a technological breakthrough is now recognized as a global environmental and public health crisis.

PFAS are dangerous because they do not easily break down in nature or in the human body. Instead, they accumulate in soil, water, animals, and people over time. Scientists have linked PFAS exposure to cancer, immune system dysfunction, liver disease, reproductive problems, developmental disorders, and other chronic illnesses. Communities around the world are now discovering contamination in drinking water, farmland, livestock, and food supplies. As awareness has grown, so has a massive wave of lawsuits against chemical manufacturers, industrial facilities, and governments accused of allowing PFAS contamination to spread unchecked. 

What Are PFAS and Why Are They Dangerous?

PFAS are a family of thousands of human-made chemicals designed to resist degradation. Their chemical structure contains strong carbon-fluorine bonds, which make them extremely durable. This durability explains both their commercial usefulness and their environmental threat. Once released into the environment, PFAS can persist for decades or even centuries.

These chemicals move easily through air, groundwater, rivers, and soil. They are absorbed by plants and animals and can bioaccumulate in living organisms. Studies have found PFAS contamination in rainwater, fish, wildlife, agricultural soils, and even human blood worldwide. Researchers now consider PFAS contamination one of the most widespread forms of industrial pollution ever documented. 

The health effects associated with PFAS exposure are extensive. Scientific studies have linked exposure to kidney cancer, testicular cancer, thyroid disease, liver damage, elevated cholesterol, immune suppression, fertility problems, hypertension, and developmental disorders in children. Some PFAS compounds may also interfere with hormone regulation and vaccine effectiveness. Because these chemicals accumulate gradually, even low-level exposure over long periods can become dangerous. 

PFAS Contamination of Soil and Agriculture

One of the most alarming aspects of the PFAS crisis is the contamination of farmland and agricultural soil. PFAS enter agricultural systems through several pathways, including contaminated irrigation water, industrial air emissions, firefighting foam runoff, and especially sewage sludge used as fertilizer. Municipal sewage sludge, often marketed as “biosolids,” has been spread on farmland for decades because it contains nutrients useful for crop production. However, the sludge can also contain concentrated PFAS from industrial waste streams and household products. 

Once PFAS enter soil, they can remain there for extremely long periods. Unlike many pollutants that degrade naturally, PFAS can persist and migrate through ecosystems. Crops grown in contaminated soil may absorb these chemicals, allowing PFAS to enter the food chain. Groundwater beneath farms can also become contaminated, affecting nearby communities and drinking water supplies. Scientists have documented PFAS movement from soil into surface water, crops, livestock feed, and eventually human food products. 

The economic consequences for farmers are devastating. Farms contaminated with PFAS may become unusable for food production. In some cases, agricultural products such as milk, meat, and vegetables cannot legally be sold because contamination levels exceed safety limits. Property values decline sharply, and farmers face enormous cleanup costs without clear government support. States such as Maine and Michigan have become major examples of agricultural PFAS contamination, where farms have been shut down or heavily restricted after testing revealed high levels of contamination. 

Damage to Livestock and Food Systems

Livestock are especially vulnerable to PFAS contamination because animals consume contaminated water, feed, and soil over long periods. Research has shown that PFAS accumulate in animal tissues, particularly in organs such as the liver, as well as in milk and eggs. Studies also suggest that PFAS can transfer from mother animals to offspring. 

Farmers in contaminated areas have reported severe impacts on animal health and agricultural productivity. In Texas, lawsuits alleged that PFAS-contaminated sewage sludge poisoned livestock, caused animal deaths, contaminated meat supplies, and harmed farm families. The contamination reportedly reached drinking water at levels far above federal health advisories. 

In Michigan, testing found dangerous PFAS concentrations in cattle raised on contaminated land. Authorities eventually restricted the land from agricultural use because of fears that contaminated beef could enter the food supply. Similar concerns have emerged in dairy farming, where contaminated milk has forced farmers to dump entire milk supplies and shut down operations. 

The livestock issue highlights a larger food security concern. PFAS contamination does not remain isolated to industrial sites. Instead, it spreads into agricultural systems that support entire communities. Once contamination enters the food chain, removing it becomes extraordinarily difficult.

The Growing Wave of PFAS Lawsuits

As evidence of harm has expanded, PFAS litigation has become one of the largest environmental legal battles in modern history. Thousands of lawsuits have been filed against manufacturers such as 3M, DuPont, Chemours, and other companies accused of producing or using PFAS while allegedly concealing knowledge of the risks. 

These lawsuits generally fall into three categories:

1. Drinking water contamination lawsuits filed by municipalities and water utilities seeking compensation for cleanup and filtration systems.
2. Environmental contamination lawsuits involving polluted soil, groundwater, and ecosystems.
3. Personal injury lawsuits brought by individuals claiming PFAS exposure caused cancer or other diseases. 

One of the most significant areas of litigation involves aqueous film-forming foam (AFFF), a firefighting foam widely used at military bases and airports. AFFF contains high concentrations of PFAS, and decades of use contaminated nearby groundwater and communities. Many lawsuits related to AFFF have been consolidated into a large multidistrict litigation case in the United States. 

Several major settlements have already emerged. 3M agreed to a multibillion-dollar settlement related to public water contamination claims, while other companies have reached agreements with states and municipalities. However, many lawsuits remain unresolved, and legal experts expect PFAS litigation to continue for years as more contamination sites are discovered. 

International legal battles are also growing. In Sweden, residents of Ronneby pursued legal action after discovering severe PFAS contamination linked to firefighting foam near an airbase. Sweden’s Supreme Court ruled that the mere presence of PFAS in human blood could constitute personal injury, setting a potentially groundbreaking precedent for future litigation worldwide. 

Government Response and Regulatory Challenges

Governments have struggled to respond effectively to the PFAS crisis. Regulatory agencies were slow to recognize the scale of contamination, and many safety standards remain incomplete or inconsistent. In the United States, the Environmental Protection Agency has begun developing drinking water standards and cleanup guidelines, but critics argue that regulation still lags behind scientific evidence. 

A major challenge is that PFAS represent thousands of different chemicals, many of which remain poorly studied. Cleanup is also technically difficult and extremely expensive. Conventional water treatment systems often cannot fully remove PFAS, and contaminated soils may remain hazardous for decades.

Some states have begun taking stronger action. Maine became the first U.S. state to ban sewage sludge spreading on agricultural land and has developed financial support programs for affected farmers. Other states are considering similar measures as contamination becomes more visible. 

Conclusion

The PFAS crisis represents a profound failure of industrial oversight, environmental regulation, and public health protection. Chemicals once celebrated for their usefulness are now contaminating ecosystems, poisoning farmland, threatening livestock, and accumulating in human bodies around the world. The damage extends far beyond polluted water supplies. PFAS contamination affects food systems, rural economies, public trust, and future generations.

The growing wave of lawsuits reflects increasing demands for accountability from chemical manufacturers and regulators. Communities affected by PFAS are seeking compensation for medical costs, environmental cleanup, agricultural losses, and long-term health damage. Yet litigation alone cannot fully solve the problem. Addressing PFAS contamination will require stronger regulation, improved scientific research, agricultural protections, and large-scale environmental remediation.

PFAS are called “forever chemicals” because they persist for generations. The legal, environmental, and human consequences of their widespread use may persist just as long.

Spotlight on Yara International in a PFAS context:

Yara International and the PFAS Debate

Yara International is one of the world’s largest fertilizer producers and a major industrial player in global agriculture. Headquartered in Oslo, the Norwegian company manufactures nitrogen fertilizers and agricultural products used across Europe, the Americas, Africa, and Asia. Because PFAS contamination has increasingly been linked to fertilizers, sewage sludge (“biosolids”), and agricultural runoff, Yara inevitably enters the broader conversation about industrial agriculture and environmental accountability.

However, it is important to distinguish between documented PFAS allegations directly involving Yara and the wider PFAS crisis affecting the fertilizer industry as a whole.

Yara’s Connection to the PFAS Issue

At present, Yara is not among the primary corporations most heavily targeted in PFAS litigation. The largest PFAS lawsuits have focused on chemical manufacturers such as 3M, DuPont, Chemours, and companies involved in firefighting foams or sludge-based fertilizers. 

Still, Yara operates in an industry increasingly scrutinized for several environmental concerns that intersect with PFAS contamination:

• fertilizer production,
• industrial chemical emissions,
• soil and groundwater pollution,
• agricultural contamination pathways,
• and waste-stream management.

PFAS concerns become especially relevant where fertilizer systems interact with sewage sludge, wastewater reuse, or industrial byproducts. Researchers and regulators are increasingly examining whether agricultural inputs can act as vectors for PFAS entering farmland and food systems. 

Environmental Cases Involving Yara

Yara has faced environmental litigation in several countries involving pollution and contamination claims, though not always specifically tied to PFAS.

According to company reporting, Yara has been involved in lawsuits in Brazil concerning alleged soil and groundwater pollution in industrial areas where fertilizer-related operations occurred. The company has denied liability in those cases. 

This matters in the PFAS discussion because PFAS contamination rarely exists in isolation. Communities affected by industrial fertilizer operations often experience overlapping contamination involving nitrates, heavy metals, sulfur compounds, industrial solvents, and persistent organic pollutants. Environmental advocates increasingly argue that intensive fertilizer production and industrial agriculture create conditions where long-term chemical contamination can spread through ecosystems with inadequate oversight.

Agriculture, Fertilizers, and PFAS Pathways

The strongest PFAS connection to agriculture today involves biosolid fertilizers — fertilizers derived from sewage sludge. These products can contain concentrated PFAS from industrial waste streams and household chemicals. When spread on farmland, PFAS can enter:

• soil,
• groundwater,
• crops,
• livestock feed,
• meat and dairy products,
• and ultimately human bodies. 

This broader crisis has cast a shadow over the fertilizer sector generally, including major multinational firms like Yara, even when they are not directly accused of PFAS wrongdoing. Critics argue that large agricultural corporations benefit from systems that historically prioritized productivity over long-term environmental toxicity.

Norway and the European Context

In Europe, environmental regulation around PFAS is becoming much stricter. Norway has generally taken a precautionary approach toward chemical regulation, and Norwegian industrial companies are under growing pressure to reduce environmental footprints and increase transparency.

Yara itself has publicly emphasized sustainability initiatives, including low-carbon fertilizer production and renewable hydrogen projects intended to reduce greenhouse gas emissions. However, critics note that climate sustainability and toxic chemical accountability are separate issues. A company may reduce carbon emissions while still operating within environmentally harmful industrial systems.

The Larger Ethical Question

The PFAS crisis raises difficult questions about industrial agriculture as a whole:

• How much chemical contamination is considered acceptable?
• Who pays when farmland becomes poisoned?
• What responsibilities do fertilizer producers have for downstream environmental damage?
• And how should governments regulate chemicals that persist for generations?

Companies like Yara sit at the center of this debate because they are deeply embedded in the global food production system. Fertilizer corporations helped enable enormous increases in agricultural productivity, but modern environmental science is revealing the hidden costs of industrial-scale chemical dependency.

Conclusion

There is currently no major body of evidence publicly identifying Yara International as a central PFAS polluter comparable to companies such as 3M or DuPont. Nevertheless, Yara operates within an agricultural and industrial ecosystem increasingly under scrutiny for contamination, chemical persistence, and environmental degradation.

As PFAS investigations expand globally, pressure is growing on all major fertilizer and agricultural corporations to demonstrate transparency, monitor contamination pathways, and ensure that farming systems do not become long-term carriers of toxic “forever chemicals.”

The PFAS issue is no longer only about chemistry. It is about trust — trust in regulators, trust in corporations, and trust that the systems feeding the world are not quietly poisoning the land beneath them.
