| Summary: | Drinking water is a crucial provision for our survival and well-being. However, it is often taken for granted. The environmental objectives in Sweden appear insufficient to ensure drinking water with good quality, because the objectives lack clear protective descriptions, which allow municipalities to determine how to interpret and ensure drinking water. The purpose of this study is to investigate barriers and opportunities for sustainable management of drinking water sources in a tourist region. In order to fulfil the purpose, the study identifies vulnerabilities in the municipal drinking water system with the help from scenario analysis of climate change and tourism development. The study also presents relevant adaptation solutions. The DPSIR framework was used as a tool to categorize and describe the studied problem and was based on a literature study and a mapping of the study area. Åre ski resort was used as a case, and it is supplied with drinking water from two groundwater beds infiltrated by Åresjön (a lake, part of a river). Åresjön is included in an objective to keep drinking water quality standards. The results show that climate change and tourism development reduces surface and groundwater quality, primarily by increasing microbiological particles. Increases in the number of tourists combined with insufficient monitoring of groundwater levels and infiltration capacity knowledge are unsustainable and are expected to reduce the amount of water in the large groundwater beds. The identified most vulnerable parts of the drinking water system are within the municipal planning process, water production and wastewater treatment. Therefore, the various adaptation solutions address these issues. Direct and indirect adaptations are necessary to ensure sufficient drinking water of good quality until 2100. Tourism development is the main driver for affecting drinking water (if no adaptation measures are implemented). === <p>20180623</p>
