WQeMSEuropean Union ProjectsProject duration: Jan 2021 to Jun 2023Monitoring the extent of the effluents in the lake provides a warning about the risk of water contamination and contributes to impact mitigation strategies, both for the drinking water production and the environmental sustainability.IntroductionWQeMS focuses its activities on the monitoring of lakes with the aim to provide an operational Water Quality Emergency Monitoring Service, which enhances our ability to deliver drinking water in all EU member states. The project exploits Sentinel satellite data for quality monitoring at a finer spatial resolution level, following validated processes with in situ data.WQeMS provides extensive information about water quality by building a multi-temporal and high spatial resolution monitoring framework. The goal is the optimization of the use of resources by gaining access to frequent acquired, wide covering and local accurate water-status information, by which citizens will gain a deeper insight and confidence for selected key quality elements of the water we drink.The project will address slow evolving phenomena such as geogenic or anthropogenic release of potentially polluting elements that can contaminate freshwater reservoirs, but also the detection of seasonal and annual changes in submerged aquatic vegetation in shallow waters, which is of high value as a quality indicator.Grumets will mainly participate in the quality/uncertainty documentation of the data and in the user feedback integration. Visualization of data uncertainty will be also further analysed.
