The Bollaertbeek catchment is a zone with mixed urban/rural land-use and is part of the surface water capturing area of the drinking water production company VMW.
Plant protection product concentrations are a problem for water quality in the catchment. Despite several extension and training campaigns on water contamination problems by PPPs, there still is a low uptake of mitigation measures.
Nitrate concentrations in surface water in the region have improved after the establishment of water quality groups, this approach is a combination of monitoring, setting up discussion groups, advising farmers on fertilization and fertilization plans
A governance strategy to decrease concentrations of plant protection products in surface water in the region will be developed building on the experience from the water quality groups and the lessons learnt from other successful cases of increased uptake of best management practices (BMPs).
