- Per- and Polyfluoroalkyl Substances (PFAS) in Sewage Sludge
While these agency actions are underway, the EPA recommends that states monitor biosolids for PFAS contamination, identify likely industrial discharges of PFAS, and implement industrial pretreatment requirements where appropriate
- An Overview of PFAS and Land-Applied Biosolids - Penn State Extension
Because PFAS do not break down easily in the environment, when biosolids with high concentrations of PFAS are used to amend the soil, they persist for long periods of time, allowing them to be transported to soil, water resources, and be absorbed by planted crops
- PFAS in Biosolids: A Review of State Efforts Opportunities for Action
PFAS in biosolids Thirty-four states, shown in green in the map below, responded to the survey This paper outlines ECOS’ findings on how these states manage biosolids, and where opportunities exist for regulation, research, and risk communication PFAS in Biosolids: A Review of State Efforts Opportunities for Action
- PFAS in Biosolids: Risk, Reality and the Road Ahead
The reality is that PFAS are ubiquitous in modern society – and we all contribute to that Wastewater treatment plants are passive receivers of these compounds, and biosolids will continue to contain low levels as long as PFAS remain in widespread use
- Underestimation of Per- and Polyfluoroalkyl Substances in Biosolids . . .
The objective of this study was to quantify 92 PFAS in biosolids collected from eight biosolids treatment facilities before and after four pathogen treatment applications: composting, heat treatment, lime treatment, and anaerobic digestion
- Managing PFAS in Biosolids and Sewage Sludge
Using biosolids as fertilizer could lead to PFAS-contaminated land and pose health risks to livestock and crops, bringing significant implications for food safety and agricultural practices Early testing and investigation not only mitigate public health risk but also reduces reputational risk
- Quantification of PFAS in soils treated with biosolids in ten . . .
Our study showed significantly higher concentrations of PFAS in biosolids-treated (treatment) soils compared to (untreated) controls
- PFAS in Biosolids: The Risks and Potential Solutions
Human exposure to PFAS from biosolids can occur through consuming contaminated food or water, or direct contact with treated soil Exposure to PFAS has been associated with health concerns, as indicated by the EPA’s draft risk assessment for common PFAS compounds like PFOA and PFOS Concerns include effects on the immune system, liver
