Longer-chain PFCAs generate more harmful disinfection by-products in aged pipes.
Per- and polyfluoroalkyl substances (PFAS) inevitably enter drinking water distribution systems (DWDS) and may interact with corrosion-derived iron particles to affect the formation of disinfection by-products (DBPs). This study investigated the influence of perfluorocarboxylic acids (PFCAs) with varying chain lengths...
