All of these methods promote the formation of hydroxyl radicals or other oxidizing agents that can oxidize PFAS and break its C−C bonds. [3] [4] However, the remediation of PFAS depends on the environmental medium where the these compounds reside. For example, the treatment of contaminated soil, biosolids and water is not the same, and risk ...

The type of PFAS remediation technology selected is often a reflection of the PFAS contamination levels and the PFAS signature (i.e. the combination of short- and long-chain PFAS substances present) in conjunction with the site-specific water chemistry and cross contaminants present in the liquid stream.
