A common question from developers is whether PFAS testing is actually required on a given site. The answer depends on site history, location and proposed use.
Common triggers include former fire training grounds, airfields, industrial facilities, landfills and sites near known PFAS plumes. Where these factors are present, regulators increasingly expect PFAS to be considered as part of the conceptual site model.
A proportionate PFAS assessment focuses investigation where risk is credible, avoiding unnecessary testing while still satisfying regulatory expectations.
