Emerging contaminants

It is becoming increasingly clear that Belgium’s soil and groundwater contain a wide range of so called ‘emerging contaminants’. For several of these substances, there is insufficient information about the scope of the problem and the associated risks.

In 2016, a consortium of Witteveen+Bos, MAVA and EnISSA was therefore commissioned by the Flanders Public Waste Agency (OVAM) to conduct an exploratory study of the presence of 1,4-dioxane and Perfluorinated Alkylated Substances (PFAS) in Flanders. Both types of contaminants are environmentally persistent and difficult to clean up. Based on the study results, 1,4-dioxane was included in a number of OVAM’s existing standard procedures. In 2017, a follow-up research study will be performed that will also devote attention to decontamination, policy and legal aspects. The PFAS project was set up in cooperation with Arcadis. In 2017, extensive field work and measurement campaigns were performed as part of this project.
