Commissioned by Water Board Rivierenland, for the first time a pilot investigation of the presence of microplastics in Dutch regional waters has been performed.

Microplastics in fresh water
Microplastics in fresh waters receive growing interest. Until now no data were available for regional waters in The Netherlands. Knowledge about the abundance of microplastic in many different water types is important in order to be able to assess the sources and dispersion of microplastics.
Sampling of different locations
Sampling took place in different water types and on different locations: starting from Groesbeek at the Dutch-German border, to The Kinderdijk in the Alblasserwaard. Microplastics were detected at all locations. For one location also waste water from a sewage treatment plant was investigated. The microplastic concentrations were much higher than in the receiving surface waters. Concentrations in these regional surface waters appeared to be very similar to those recently reported for the Five Great Lakes (USA) and for Lake Geneva (Switzerland).
