KWR generates knowledge to enable the water sector to operate water-wisely in our urbanised society. At KWR, we have a sense of professional and social responsibility for the quality of water. Our scientific findings and the resulting practical innovations contribute, worldwide, to a sustainable water provision in the urban watercycle.
How are you performing research on Citizen Science, taking part in Citizen Science activities and/or supporting Citizen Science?: 
I have initiated and coordinated five unique citizen science projects in the domain of (drinking) water research in the Netherlands conducted in co-operation with four different organizations and over 1000 volunteers.

Brief description of project: 
1. The Freshness of Water dealt with the microbiological stability of drinking water. Participants took water samples at their home and performed analyses themselves. Samples were also transported to the KWR laboratory where the latest DNA techniques in the field of ‘Next Generation Sequencing’ were performed, making it possible to classify millions of bacteria at the DNA level. Participants were recruited via a Facebook campaign. 2. In the Clean Water Experiment, hundreds of participants received a special toolbox, containing various instruments to carry out quality measurements on the city’s surface water, including an E.coli, colour, temperature, and odour experiment. Citizens were invited to research the quality of the water in the city over a period of three months, and asked to upload their results to a dedicated website. Participants were recruited by means of generic invitation to the general public, both online and offline. 3. In the Citizen Science and Lime project, the participants have determined the hardness and lime-scaling of their tap water at home, using a simplified boiled water test and a ‘drop test’. The drop tests was carried out twice; once on water directly from the tap and once on 5 minutes boiled water. Invitations to participate in the project were sent to 1500 selected addresses. 4. In the project Citizen Science and Lead, citizens were invited to participate in the research into lead water pipes. Citizen scientists contributed in two measurement rounds, which included three variants with different research steps, ranging from taking pictures, taking samples, measuring pipes, to testing for the presence of lead by using indicator strips. Invitations to participate in the project were sent to more than 1255 selected addresses with houses built before 1960, because houses built before that time, may still have in-house lead water pipes. URL: 5. The Citizen Science and Hardness project is in many respects equal to the above mentioned citizen science and lime project, yet differs from it in two ways. First, participants were invited to take measurements on three different occasions over a period of seven months: before, during and after the work on a particular transport pipeline. Second, participants were exclusively asked to carry out the ‘hardness drop test’ with water directly from the tap. Invitations to participate in the project were sent to 2384 randomly selected addresses. URL:
