An unsettling revelation is shaking the foundations of American agriculture. For decades, a government-endorsed fertilizer has quietly poisoned farmlands with hazardous chemicals, threatening both farmers and the broader food chain. A new investigation has uncovered that municipal sewage, commonly referred to as “black sludge” and widely used as fertilizer, contains dangerous levels of PFAS, a class of chemicals with long-lasting effects on both the environment and human health. The consequences of this discovery are reverberating across rural communities, leaving farms in jeopardy and consumers questioning the safety of their food.
The Growing PFAS Contamination Crisis
The practice of using municipal sludge as fertilizer has been encouraged by the U.S. Environmental Protection Agency (EPA) for years. This sludge, rich in nutrients, was seen as an efficient way to recycle waste into agricultural production. However, the dark side of this process is now becoming more apparent. Recent tests have revealed that the sludge often contains per- and polyfluoroalkyl substances, or PFAS, commonly known as “forever chemicals” due to their inability to break down in the environment. These chemicals have been linked to severe health conditions, including certain cancers, high cholesterol, and developmental issues in babies.
Impact on Farmers and Ranchers
Farmers like Jason Grostic, a third-generation cattle rancher in Michigan, have found themselves at the epicenter of this unfolding crisis. In 2020, tests revealed that the sludge fertilizer Grostic used on his property had contaminated his land with PFAS. Michigan’s health department swiftly issued a health advisory for his beef, effectively shutting down his business. Grostic expressed the anxiety shared by many in his situation, stating, “This stuff isn’t just on my land. People are scared to death that they’re going to lose their farm, just like I did.”
The financial toll on farmers is enormous. In Texas, a farm halted its cattle sales after discovering high PFAS concentrations on their land. With no income from their livestock, they are left to manage a herd they can no longer sell, all while scraping together a living from odd jobs. These families, who rely entirely on farming for their livelihood, are facing an uncertain future.
Public Health Concerns and the Spread of PFAS
PFAS contamination doesn’t just stay on farms. The chemicals can easily enter the food chain through crops grown on contaminated soil or animals that graze on it. As the food moves from farm to table, these harmful substances make their way into the meals of unsuspecting consumers. Research has shown that pregnant women can pass PFAS on to their babies, and the chemicals’ presence in the environment is widespread, extending far beyond agricultural fields.
PFAS have infiltrated water supplies globally. A study found concerning levels of the chemicals in waterways near textile manufacturing centers in Bangladesh, while another investigation discovered PFAS in water supplies far from known contamination sites. This pervasive reach highlights the difficulty in containing these chemicals once they enter ecosystems.
The Scope of the Problem
The numbers are staggering. According to the New York Times, more than two million dry tons of municipal sludge were spread across 4.6 million acres of farmland in 2018 alone. This extensive use of contaminated fertilizer raises alarming questions about the safety of the food produced on these lands.
In 2022, the Environmental Working Group (EWG) estimated that around 20 million acres of farmland across the U.S. could be contaminated with PFAS. They reported that at least 5% of farms in the country are using wastewater sludge, exposing millions of acres to potentially harmful substances. For consumers, the problem is compounded by a lack of transparency regarding where their food comes from and whether it may have been grown on contaminated fields or fed with compromised feedstock.
States and Farmers Take Action
In response to mounting concerns, Maine took a bold step in 2022 by banning the use of sewage sludge on agricultural fields. The state is leading the charge, but it remains one of the few to take such decisive action. Other states have started testing for PFAS on farms, but the EPA continues to endorse the use of sludge as fertilizer, despite the risks.
Janine Burke-Wells, executive director of the North East Biosolids & Residuals Association, argues that banning sludge is not the right solution. She believes the key lies in preventing PFAS from entering wastewater in the first place. According to Burke-Wells, banning PFAS in consumer products or requiring industries to clean their wastewater before it reaches treatment plants would address the root cause of the contamination.
Some states are heeding this advice. Colorado has passed legislation to ban PFAS in many consumer products starting in 2026, while Pennsylvania is working on a bill to eliminate these chemicals from items like cleaning products, food packaging, dental floss, and textiles by 2027. These steps represent a shift in the fight against PFAS, focusing on limiting their use before they reach farms and homes.
The Need for Greater Awareness and Action
Despite these state-level initiatives, much remains to be done to protect the public from the dangers of PFAS. Consumers currently have little way of knowing if the food they purchase has been exposed to these chemicals. The lack of labeling or traceability in food production leaves the public in the dark about the potential risks in their diet.
Burke-Wells’ push for upstream solutions—preventing PFAS from reaching wastewater facilities—is an essential strategy. Limiting PFAS use in everyday products could significantly reduce the volume of these chemicals entering sewage systems and, by extension, agricultural fields.
What Comes Next?
The PFAS contamination crisis is far from over. Farmers, many of whom are unaware that their fields are contaminated, are left grappling with the financial and emotional toll. Consumers, meanwhile, face a silent threat in the food supply. Without significant action from both regulators and industries, the contamination will likely continue to spread, posing long-term risks to public health and the environment.
Water Filtration Helps
Given the widespread contamination of PFAS in water supplies, reverse osmosis (RO) filtration systems offer a practical solution for households concerned about their water quality. RO systems effectively remove PFAS from drinking water by forcing water through a semipermeable membrane, filtering out even tiny chemical particles. Additionally, whole-home water conditioners can improve the overall safety of household water by treating water at the point of entry, ensuring that all taps deliver cleaner, safer water. For households near known contamination sites or agricultural lands, investing in these systems may provide an added layer of protection against PFAS exposure.
