Abstract:
Sewage sludge and biosolids have been used for land application since the early 20th century due to their agricultural benefits. Sewage sludge treatment does not specifically remove PFAS, and treated biosolids can therefore contain these persistent contaminants. PFAS contamination in biosolids has received growing attention nationwide, with some cases drawing national media coverage. There are currently no federal regulations limiting PFAS concentrations in land-applied biosolids, but some states have enacted PFAS-specific regulatory limits, and several others have proposed legislation under review. This review summarizes the current regulatory landscape surrounding PFAS in biosolids and provides an overview of applicable analytical methods.
