Pesticides in Dutch sources for drinking water supply

“For decades, pesticides are widely considered as a major threat for the quality of groundwater and surface water sources of drinking water. We present the results of a comprehensive inventory of observed pesticides and metabolites throughout the sources of drinking water in the Netherlands (2018-2022). For surface water we distinguish between observations in intake water and pre-treated dune filtrate, which are two major sources for drinking water production. For groundwater, we distinguish between observations in observation wells, individual abstraction wells and the abstracted groundwater as a whole. We also present the Removal Requirement Index to monitor the level of required purification treatment.”
