Vattenkommunikation, spårbart dricksvatten och aktörer i branschen

Sammanfattning: Due to climate change, chemical use and physical impact on natural waters, the vulnerability and load of drinking water distribution systems is likely to increase. Therefore traceable drinking water regarding origin and quality analysis through a QR code by the taps in people’s homes, might become necessary. The QR code could make up an easy communication channel for information exchange between user and producer. This study aims to map the actors within the drinking water distribution chain in Sweden and to discuss the possibilities and prerequisites for traceable drinking regarding water plant, aquifer and quality analysis in the municipality of Svalöv. The study focuses on actors involved with groundwater, production and distribution, thus not on surface water. Six interviews with people of different professions within the distribution chain were conducted and regulations with instructions for governmental authorities were reviewed. The actors are many and often have complex relationships. Four professions and three authorities were found to play central roles within the distribution chain: hydrogeologists, drilling technicians, society planners, water producers, the Swedish Food Agency, the County Administrative Boards and the Geology Survey of Sweden. Traceability regarding water plants for municipal users is possible today, for those whose water originates from one water plant and one aquifer. Quality analyses in real-time for every relevant parameter is not implemented today and might not be possible in the future. Instead, measurable parameters in real-time such as temperature, pH, turbidity and electrical conductivity could indicate when the entire spectrum of parameters should be analyzed.
