Impactanalyse stoppen van gebruik van bestrijdingsmiddelen in grondwaterbeschermingsgebieden: Quickscan

The quickscan aims to gain a first general understanding of the impact of a nationwide pesticide use ban in groundwater protection areas (GWP areas). The Netherlands has 158 GWB areas with an area of 94,310 ha. These areas occur throughout the Netherlands, mainly on the lighter (sandy) soils. Of the 39 substances detected in at least 3 groundwater samples above the drinking water signalling value in the period 1963- 2022, 10 substances are from pesticides that still have an authorisation as a plant protection product or biocide within the Netherlands. Of these, 6 substances are a herbicide or a metabolite of a herbicide. The consequences of a ban on pesticide use in GWB areas are greatest for perennial crops and high balance crops.
