Abstract: Per- and polyfluoroalkyl substances (PFAS) –also known as forever chemicals– are synthetic compounds characterized by their strong carbon–fluorine bonds, which confer exceptional chemical stability and resistance to degradation. This persistence has led to widespread environmental contamination and bioaccumulation. PFAS transport and accumulation are strongly influenced by adsorption at environmental interfaces, particularly the air–water and water–sediment boundaries. To investigate the impact of these processes in a coastal setting, a numerical modeling approach was embraced to investigate the Mar Menor coastal lagoon (southeastern Spain) using the Delft3D 4 suite. Hydrodynamics and wave dynamics were simulated with Delft3D-FLOW and Delft3D-WAVES, while adsorption–desorption processes and Lagrangian particle transport were represented through Delft3D-WAQ and Delft3D-PART. This study provides insights into PFAS behaviour in aquatic environments and supports improved understanding of their environmental fate.
