What does PFOS in water mean in practice?
Detection requires specialized testing because PFOS is often present in trace concentrations without organoleptic characteristics.
When does it matter?
The behavior of PFOS on sorbents differs from shorter PFAS, so the results cannot be generalized to the entire group.
Which solutions are related to it?
Certified adsorption systems, resins or RO are used with regular monitoring of bed breakdown.
