No problem - thankyou

Thanks mate however am not talking about PFA, am talking about PFAS (per- and polyfluoroalkyl substances). thanks anyway.

Wondering if there could be any adverse effects from PFAS (per- and polyfluoroalkyl substances) that may affect the integrity/lifespan etc of concrete (esp. foundations)? Whilst I do appreciate that that organic content in cements/concretes, <eg - lime> may act as a preferential sorption media over surrounding soils (depending on the chemistry of the soils), I cannot figure any deleterious integrity impacts to the concrete from the PFAS. When considering construction, I would have thought only real issue is in regard to disposal of concrete at end of life (re: presence of PFAS)). Any assistance appreciated. Thanks.
