Local challenges and water contaminants
Plant protection product concentrations are the main problem for the water quality in the catchement. Due to the establishment of water quality groups (CVBB) which focuses on nitrate concentration in surface water the nitrate concentrations in surface water are under control.
The surface water of the Bollaertbeek is the capturing area of the drinking water production company De watergroep. The water of the Bollaertbeek is stocked in De verdronken weide from where the surface water is purified to drinking water.
