In this citizen science research project of KWR and the drinking water company WML, the clients of a water company are, for the first time, participating as researchers in a scientific study of drinking water hardness and lime-scaling. The research is being conducted at and around the WML pumping station in Pey-Echt. Besides knowledge about lime-scaling it will be giving us new insight into the socio-scientific value and significance of citizen science.
Citizens measure lime-scaling themselves
Together with more than 130 citizen water scientists, KWR and WML will be researching the hardness and lime-scaling of drinking water. A unique aspect of this research is that invitations to participate in the project were sent to more than 1,000 selected addresses, which resulted in a very diverse group of participants. Using a simplified boiled water test and a ‘drop test’, the participants will determine the hardness and lime-scaling of their water. They’ll carry out drop tests once on water directly from the tap and once on boiled water. In this way, the participants will gain more insight into the composition of their drinking water, and WML will get a more refined monitoring network.
This ‘Citizen Science and Lime’ project, together with the ‘Citizen Science and Lead’ project (with Dunea) and the ‘Citizen Science and Hardness’ project (with Brabant Water), which starts later this year, is part of the joint effort on the part of KWR and the drinking water sector to further explore the significance of citizen science for the sector. This line of research builds upon the ‘Freshness of Water’ citizen science pilot project of 2016.
