This webinar explores how PFAS risk evaluation is carried out in soils and excavated materials in Flanders. Experts from VITO will introduce the scientific basis of PFAS norm-setting, highlight key uncertainties and sensitivities, and explain how background exposure and reuse of PFAS‑containing soil are assessed in practice. The session will also address how these scientific insights translate into policy and what this means for ongoing and future projects. Following the introduction, various stakeholders will share their perspectives to foster a constructive and nuanced dialogue on PFAS management in the field.
