ExpectedOutcome:
In line with the European Green Deal’s zero pollution ambition, successful proposals will contribute to halting and preventing pollution of freshwater and soils, and consequently also protecting biodiversity, as addressed by several impacts under Destination ‘Clean environment and zero pollution’, in particular “Advanced understanding of diffuse and point sources of water pollution in a global and climate change context, enabling novel solutions to protect water bodies, aquatic ecosystems and soil functionality, and further enhancing water quality and its management for safe human and ecological use, while fostering the European position and role in the global water scene.”
Project results are expected to contribute to some of the following expected outcomes:
- Wider use of an enhanced knowledge base and better understanding of pollution sources, pathways and impacts, including surface hydrology, aquifers and receiving water bodies, as well as the synergistic effects of multiple stressors on groundwater quality.
- Implement advanced prevention and mitigation strategies to protect groundwater against pollution induced by global and climate change, including anticipative approaches preparing for future or emerging challenges.
- Apply effective risk assessment and risk management strategies enabling early warning systems and delivering ready-made outcomes for decision-making and governance.
- Deploy innovative monitoring strategies, including advanced sensors, tracers and analytical methods, and integration of IT tools/platforms and advanced modelling.
- Broad uptake of advanced knowledge, breakthrough solutions and innovative technologies to enhance the competitiveness of the EU water sector and foster the EU’s position and role in the global water scene.
- Increasing the EU scientific and technological base on measures to manage groundwater quality and providing evidence and guidance for policy-making and implementation.
- Science and evidence-based implementation of the European Green Deal and the Sustainable Development Goals, notably the SDG 6 “Ensure availability and sustainable management of water and sanitation for all”.
Scope:
The European Union has made noticeable progress in terms of reducing concentrations of nutrients in groundwater and in rivers through the implementation of dedicated policy measures. However, Member States identified that diffuse pollution is still a significant pressure that affects 35% of the area of groundwater bodies[1], while quality standards (pesticides, herbicides, etc.) were exceeded in 15% of the groundwater bodies studied. Climate change and increasing water demand will exert significant pressures on groundwater quality, notably where the combined effect of reduced hydrological flows, water table depletion and sea level rise endanger the integrity of coastal aquifers and groundwater quality due to saline water intrusion. Extreme events like higher tides, storm surges and inland flooding events, and consequent pollutant and pathogen runoff, will put at risk wetlands and reservoirs, estuaries and ecosystems, jeopardising an efficient and qualitatively good groundwater recharge. Rising water tables in urban and rural areas, caused by e.g. higher sea level, changing water use or variable precipitation patterns, could potentially affect pollution sources (sewage, runoff infiltration, dilution of soil pollutants, salinization, etc.) and deteriorate the quality of groundwater.
Additional knowledge is needed to understand the synergistic effects and risks of multiple stressors and pollutants on groundwater quality to better evaluate the impacts of global and climate change, particularly in highly vulnerable areas affected by diffuse pollution, anthropogenic activities and/or water table fluctuations. Actions in this field should aim to identify and assess sources and pathways of groundwater pollution to inform risk management plans at basin/regional scales, with particular consideration of aquifer recharge with reclaimed water and persistent pollutants.
Further developments are expected in terms of cost-efficient monitoring strategies, which could include new tracers and sensors, increased sampling and analytical capacity, as well as integrating IT advances and geophysical modelling.
Proposals in this area should assess possible options and anticipate novel strategies to protect groundwater quality by considering the harmful effects of and threats from climate change. Actions in this field should focus on preventive measures and consider technological and non-technological solutions, and should engage with policy and decision-making bodies.
In general, the participation of academia, research organisations, utilities, industry and regulators is strongly advised, as well as civil society engagement whenever necessary, also aiming to broaden the dissemination and exploitation routes and to better assess the innovation potential of developed solutions and strategies.
If appropriate, applicants are advised to seek complementarities and synergies, while avoiding duplication and overlap, with relevant actions funded under Horizon 2020 calls[2], as well as targeted topics supported in the last Horizon 2020 and Horizon Europe calls, addressing micro/nano-plastics, persistent and mobile pollutants, such as per- and polyfluoroalkyl substances (PFAS), pharmaceuticals and contaminants of emerging concerns (CECs), pathogens and antimicrobial resistance.
In order to better address some or all of the expected outcomes, international cooperation is strongly encouraged.
