This map indicates at which extractions plant protection products have been found as potential or current problem substances. The map is based on information from the area files for drinking water abstractions. The parties involved (municipality, province, drinking water company and water manager) make an inventory of current and future risks to water quality in an area file for a production site. These risks can be both substantive and policy-related in nature. The area dossiers also identify possible measures on which the parties will make agreements in a subsequent phase. The coordinators also shape the process of making agreements and monitor the progress of the implementation of measures as agreed.
