Groundwater is a critical resource providing 50% of all water used domestically and 25% of all water used for irrigation worldwide. However, despite the crucial role of groundwater, most of the subsurface remains unexplored for groundwater resources and we primarily use shallow onshore aquifers, limiting our knowledge and understanding of the potential for deeper groundwater. Recent research estimates that the volume of water in such deeper offshore aquifers is one hundred times greater than the amount extracted from the Earth's subsurface in the 20th century. In the context of ongoing water crises, the UN has placed emphasis on the importance of exploring for deep-onshore and offshore freshwater, among other unconventional water resources, to develop resilience of water-scarce communities against climate change. However, to date, there has been little or no exploration of deep-coastal and offshore resources in Europe. The primary challenge hindering the utilization of this new water source is the lack of knowledge. The RESCUE project aims to bridge this gap by building better understanding of deep-coastal and offshore freshwater aquifers through data collection, experiments, and modelling. We will also evaluate if these aquifers are financially viable to exploit, produce guidelines for their use and regulation, and disseminate information to key stakeholders about them. This will enable local and regional policy makers to lay the foundations for the consideration and use of these new resources. The sustainable use of deep-coastal and offshore groundwater will ultimately help secure a steady supply of water to both population and industry, in times of hydroclimatic extremes.

地下水是一种关键的资源，可提供全国所有用水的50％，全球用于灌溉的所有水的25％。但是，尽管地下水的作用至关重要，但大多数地下仍未探索地下水资源，我们主要使用浅水含水层，从而限制了我们对深层地下水潜力的知识和理解。最近的研究估计，如此深的离岸含水层中的水量比20世纪从地球地下提取的数量高一百倍。在持续的水危机的背景下，联合国强调了探索对深度和海上淡水的重要性，以及其他非常规的水资源，以发展水砂社区的弹性抵抗气候变化。但是，迄今为止，欧洲的深层和海上资源几乎没有探索。阻碍这种新水源利用的主要挑战是缺乏知识。救援项目旨在通过数据收集，实验和建模来更好地了解深层和近海淡水含水层。我们还将评估这些含水层在财务上是否可行，可以利用，制定其使用和监管指南，并将信息传播给关键利益相关者。这将使地方和区域政策制定者能够为这些新资源的考虑和使用奠定基础。在氢化气候极端时期，深层和离岸地下水的可持续使用最终将有助于为人口和工业提供稳定的水供应。
