Dublin Airport warns 'forever chemicals' in soil on its lands could impact MetroLink project

The Daa said it was building an apron in 2023 when the first evidence of contamination was discovered.

Dublin Airport warned Government officials and regulators that Ireland had no sustainable system for dealing with soil contaminated by so-called “forever chemicals” linked to firefighting foam.

Internal records detail how the airport's operator Daa said even extremely low levels of contamination with per- and polyfluoroalkyl substances (PFAS) meant excavated soil would have to be exported abroad because no Irish facility could handle it.
