The Hidden Dangers of Sewage-Based Fertilizers: Texas County Declares Emergency Over PFAS Contamination
Share
In a concerning development, Johnson County, Texas, has declared a state of emergency following the discovery of dangerously high levels of per- and polyfluoroalkyl substances (PFAS) on its farmland. PFAS, also known as "forever chemicals," do not break down in the environment and pose severe health risks, including cancer, developmental disorders, and reproductive issues (Tabuchi, 2025). This alarming situation highlights the dangers associated with the use of fertilizer made from treated sewage sludge, a practice that has increasingly come under scrutiny.
The Crisis in Johnson County
The issue first came to light in 2023 when county investigators found high PFAS concentrations at two cattle ranches. According to reports, the contamination stemmed from a neighboring farm that had used sewage-based fertilizer produced from wastewater treatment facilities in Fort Worth (Tabuchi, 2025). The chemicals leached into the soil, crops, and water sources, endangering both agricultural products and livestock.
In response, county officials have urgently called upon Texas Governor Greg Abbott to seek federal disaster relief. The proposed emergency measures include rigorous testing of drinking water, environmental cleanup efforts, and even the euthanization of cattle that have been exposed to the contaminated soil and feed (Tabuchi, 2025). This marks one of the most significant responses to PFAS contamination in recent years and raises broader concerns about the safety of sewage-derived fertilizers.
The Widespread Threat of PFAS
PFAS are synthetic chemicals commonly found in nonstick cookware, stain-resistant fabrics, and firefighting foams. Their persistence in the environment makes them a major public health concern, as they accumulate in the human body over time. Studies have linked PFAS exposure to several serious health conditions, including kidney and liver disease, immune system suppression, and endocrine disruption (Tabuchi, 2025). Given these risks, the agricultural use of PFAS-contaminated fertilizers poses a significant threat to food safety and environmental health.
One of the most pressing concerns regarding PFAS exposure is its detrimental effect on fertility. Research indicates that PFAS can interfere with hormonal balance, leading to reduced fertility in both men and women. The chemicals have been associated with irregular menstrual cycles, lower ovarian reserves, and decreased sperm quality, making conception more difficult (Tabuchi, 2025). In regions where agricultural contamination is prevalent, these risks become even more pronounced, potentially affecting entire communities. Addressing PFAS pollution is not just an environmental issue—it is a critical step toward safeguarding public health and ensuring reproductive well-being.
