Plastic Spotter


Download the CrowdWater app and register. Observe a canal or river, preferably from a bridge, and add your measurement location to the map. Share a picture of the water and indicate if the water is running, which part of the canal or river you have investigated and how much plastic you see. To get a good overview of the distribution of the plastic on this location, add a new measurement to the same location every few days. Canoes are available to investigate the plastic in more detail and eventually clean it up!


Investigate how much plastic can be found in the canals and other waters of the city Leiden in the Netherlands. Where does the plastic come from and how much of it will eventually end up in the sea and be a part of the infamous plastic soup
