Aqueous film-forming foam, used in firefighting, and biowastes, including biosolids, animal and poultry manures,
and composts, provide a major source of poly- and perfluoroalkyl substances (PFAS) input to soil. Large
amounts of biowastes are added to soil as a source of nutrients and carbon. They also are added as soil
amendments to improve soil health and crop productivity. Plant uptake of PFAS through soil application of
biowastes is a pathway for animal and human exposure to PFAS. The complexity of PFAS mixtures, and their
chemical and thermal stability, make remediation of PFAS in both solid and aqueous matrices challenging.
Remediation of PFAS in biowastes, as well as soils treated with these biowastes, can be achieved through preventing
and decreasing the concentration of PFAS in biowaste sources (i.e., prevention through source control),
mobilization of PFAS in contaminated soil and subsequent removal through leaching (i.e., soil washing) and
plant uptake (i.e., phytoremediation), sorption of PFAS, thereby decreasing their mobility and bioavailability (i.
e., immobilization), and complete removal through thermal and chemical oxidation (i.e., destruction). In this
review, the distribution, bioavailability, and remediation of PFAS in soil receiving solid biowastes, which include
biosolids, composts, and manure, are presented.
