By combining cutting-edge monitoring, real-time IoT (Internet of Things)  tools, historical records, and citizen science, the project delivers a missing international, standardised online spring hydrological and ecological database, a powerful tool for long-term ecosystem tracking and sustainable conservation of groundwater and its associated surface ecosystems. Through diverse living labs across Europe, SentinelSprings fosters inclusive conservation, empowers local communities, and informs science-based policy. Explore how we’re turning springs into early warning systems, securing clean water, ecosystem resilience, and sustainable use for generations to come.
