How “Forever Chemicals” Are Contaminating America’s Farmland: A Growing Crisis

For decades, American farmers have been encouraged by government agencies to use municipal sewage sludge as a nutrient-rich fertilizer on millions of acres of farmland. This practice was intended to recycle waste products and prevent the accumulation of sludge in landfills. However, recent research has revealed that this sludge, which is made from the sewage flowing from homes and industries, contains hazardous chemicals known as per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals.” These substances, which do not break down in the environment, are now being detected on farmland across the United States, raising alarm over their potential impact on public health, agriculture, and the environment.

The Hidden Dangers of Sewage Sludge

PFAS are a group of synthetic chemicals that have been widely used in a variety of products, including nonstick cookware, water-repellent fabrics, firefighting foam, and food packaging. They are called “forever chemicals” because they do not break down over time, persisting in the environment and accumulating in the human body. Exposure to PFAS has been linked to several serious health issues, including increased risks of cancer, liver damage, thyroid disease, and developmental problems in children.

Despite these risks, PFAS have been largely unregulated in the United States, even as evidence of their dangers has mounted. The use of sewage sludge as fertilizer has been promoted by the Environmental Protection Agency (EPA) since the 1970s, under the assumption that it was a safe and beneficial way to dispose of waste. However, as PFAS have made their way into the sewage system, they have contaminated the sludge used on farms, leading to widespread pollution of agricultural land.

Contamination Across the Nation

The problem of PFAS contamination is not isolated to one region but is being discovered across the country. States like Michigan, Texas, Maine, New York, and Tennessee have all reported cases of farmland contamination. In some instances, these chemicals have been detected at alarmingly high levels, leading to fears that they may be entering the food chain through contaminated crops and livestock.

For example, in Michigan, one farm was shut down after tests revealed extremely high levels of PFAS in the soil and cattle. This led to the state permanently prohibiting the use of the property for agriculture. In Maine, which has taken a leading role in addressing this issue, the use of sewage sludge on agricultural fields has been banned since 2022. The state has also begun systematic testing of its farms, discovering contamination on 68 out of 100 farms tested so far.

Impact on Farmers and the Agriculture Industry

The discovery of PFAS contamination has had devastating effects on the livelihoods of farmers. In Texas, for instance, ranchers have reported the deaths of cattle, horses, and other animals after sludge fertilizer was applied to neighboring farmland. The chemicals were detected in surface water at levels far exceeding the EPA’s safety standards for drinking water. In response, affected farmers have filed lawsuits against the fertilizer providers, including Synagro, which is accused of distributing contaminated sludge.

Farmers like Tony Coleman of Johnson County, Texas, have seen their herds decimated and their livelihoods threatened by these toxic substances. Despite working tirelessly to care for their animals, they fear that their farms will never recover. The financial strain has forced some to take on additional jobs and dip into their savings just to stay afloat.

The Role of the EPA and the Regulatory Failures

At the heart of this crisis is the EPA, which has long promoted the use of sewage sludge as a safe fertilizer without adequately regulating the presence of PFAS. While the agency has set limits on heavy metals and pathogens in sludge, it has failed to address the growing evidence of PFAS contamination. This lack of regulation has left farmers vulnerable to the consequences of using contaminated fertilizer, with little recourse for the damage caused.

Recently, the EPA has begun to acknowledge the risks posed by PFAS, issuing new guidelines for drinking water and designating certain types of PFAS as hazardous substances. However, these actions have come too late for many farmers who have already been affected by the widespread contamination. The agency is now studying the potential risks of PFAS in sludge fertilizer, but many are calling for more immediate and stringent regulations to protect public health and the environment.

Solutions and the Way Forward

As the scale of PFAS contamination becomes clearer, there is a growing consensus that more needs to be done to address this issue. In Maine, efforts are being made to assist affected farmers by helping them transition to other uses for their land, such as growing non-food crops or installing solar panels. Michigan, meanwhile, is focusing on reducing PFAS levels in industrial wastewater and has banned the use of sludge with high levels of the chemical.

However, many experts argue that the only way to truly tackle this problem is to address it at the source. This would involve stricter regulations on the use of PFAS in consumer products and requiring industries to clean their wastewater before it reaches treatment plants. Without these measures, the cycle of contamination is likely to continue, with devastating consequences for the agriculture industry and public health.

The use of sewage sludge as fertilizer, once seen as a sustainable practice, has now become a source of widespread environmental contamination. The presence of PFAS in this sludge has exposed a significant regulatory gap that has allowed these dangerous chemicals to proliferate across the nation’s farmlands. As the full extent of the contamination is revealed, it is clear that immediate and decisive action is needed to protect both farmers and consumers from the long-term effects of PFAS. The responsibility lies not only with the EPA but also with state governments, industry leaders, and the public to demand safer practices and stricter regulations to prevent further damage.
