Matrix Detail
Aquarden: PFOS-based AFFF material: 3M Lightwater produced prior to 2002. Lightwater produced before 2002 contains both short-chain and long-chain PFAS, including the C8 compounds perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA)
Data Detail
PFAS quantified in the influent or effluent of the SCWO experiments and observed decrease in pH and COD
