- Analysis of the geological control on the spatial distribution of potentially toxic concentrations of As and F- in groundwater on a Pan-European scalePublication . Giménez-Forcada, Elena; Luque-Espinar, J. A.; López-Bahut, T.; Grima-Olmedo, Juan; Jiménez-Sánchez, Jorge; Ontiveros-Beltranena, Carlos; Elster, Daniel; Skopljak, Ferid; Voutchkova, Denitza; Hansen, B.; Hinsby, Klaus; Schullehner, Jörg; Malcuit, Eline; Gourcy, Laurence; Szőcs, Teodóra; Gál, Nóra; Porbjörnsson, Daði; Tedd, Katie; Borozdins, Dāvis; Rosenqvist, Lars; Debattista, Henry; Felter, Agnieszka; Cabalska, Jolanta; Mikołajczyk, Anna; Pereira, Ana Paula Teixeira; Sampaio, José; Perşa, Diana; Pantic, Tanja Petrović; Rman, Nina; Arnó, Georgina; Herms, Ignasi; Rosenqvist, LarsABSTRACT: The distribution of the high concentrations of arsenic (As) and fluoride (F-) in groundwater on a Pan-European scale could be explained by the geological European context (lithology and structural faults). To test this hypothesis, seventeen countries and eighteen geological survey organizations (GSOs) have participated in the dataset. The methodology has used the HydroGeoToxicity (HGT) and the Baseline Concentration (BLC) index. The results prove that most of the waters considered in this study are in good conditions for drinking water consumption, in terms of As and/or F- content. A low proportion of the analysed samples present HGT≥ 1 levels (4% and 7% for As and F-, respectively). The spatial distribution of the highest As and/or F- concentrations (via BLC values) has been analysed using GIS tools. The highest values are identified associated with fissured hard rock outcrops (crystalline rocks) or Cenozoic sedimentary zones, where basement fractures seems to have an obvious control on the distribution of maximum concentrations of these elements in groundwaters.
- Assessment of chloride natural background levels by applying statistical approaches. Analyses of European coastal aquifers in different environmentsPublication . Pulido-Velazquez, D.; Baena-Ruiz, L.; Fernandes, Judite; Arnó, Georgina; Hinsby, Klaus; Voutchkova, D. D.; Hansen, B.; Retike, I.; Bikse, J.; Collados-Lara, A. J.; Camps, V.; Morel, I.; Grima-Olmedo, J.; Luque-Espinar, J. A.ABSTRACT: Estimated natural background levels (NBLs) are needed to assess groundwater chemical status according to the EU Groundwater Directive. They are commonly derived for different substances by applying statistical methodologies. Due to the complexity of the sea water intrusion process, some of those methods do not always provide appropriate assessment of chloride NBLs. This paper analyzes the applicability of different NBL estimation methods in five EU coastal aquifers with significant differences in available datasets and hydrogeological set-tings. A sensitivity analysis of results to different constraints was performed to remove samples with anthro-pogenic impacts. A novel statistical approach combining different methods to identify the range of chloride NBLs is proposed. In all pilots the estimated NBLs were below 85 mg/L and fitted well with previous studies and expert judgment, except Campina del Faro aquifer (the maximum being 167.5 mg/L). Although this approach is more time consuming, it provides a more robust solution.
- A Geological Service for Europe: building trust through interdisciplinary and intersectoral collaborationPublication . Hollis, Julie; Calcagno, Philippe; Bertrand, Guillaume; de Oliveira, Daniel Pipa Soares; Negrel, Philippe; Díaz-Martínez, Enrique; La Vigna, Francesco; Poyiadji, Eleftheria; Tonné, Nathalie; Van Heteren, Sytze; Dakin, Nicola; Hinsby, Klaus; Van Der Keur, Peter; Siddiqi, Gunter; Čápová, Dana; Pizzocolo, FrancescoABSTRACT: Geology encompasses all of the Earth sciences and thus is multidisciplinary. It does not respect geopolitical borders, so requires teamwork across disciplines and between nations. Applying geological solutions to climate change increasingly requires transdisciplinary teamwork. This extends well beyond the geosciences to inform on issues of universal concern, e.g., deployment of renewable energy, management of groundwater resources, mitigation of climate-induced geohazards, and more. To achieve sustainability and success in these fields, it is essential to employ knowledge of subsurface, land, and subsea geology for the discovery, tracking, preservation, regulation, and exploitation of resources. This knowledge also supports integrated and coherent surface and subsurface spatial planning and the creation of cohesive laws guided by scientific insights. This in turn requires multi-stakeholder collaboration between scientific and governmental agencies, industry, and civil society, from research design to data and knowledge application. Such a broad spectrum of engagement is at the heart of the concept of a Geological Service for Europe, founded on a long history of collaboration between the Geological Surveys of Europe –extending networks, fostering innovation, sharing knowledge, building capacity and common standards. Given the current lack of public knowledge and negative perceptions of geology, collaborative efforts based on objective science can have a significant impact on building trust. This contribution highlights the collaboration of the Geological Surveys of Europe with non-geoscientific partners in serving society, supporting nature, and delivering the Green Deal.
- Mapping and understanding Earth: Open access to digital geoscience data and knowledge supports societal needs and UN sustainable development goalsPublication . Hinsby, Klaus; Négrel, Philippe; de Oliveira, Daniel Pipa Soares; Barros, Renata; Venvik, Guri; Ladenberger, Anna; Griffioen, Jasper; Piessens, Kris; Calcagno, Philippe; Götzl, Gregor; Broers, Hans Peter; Gourcy, Laurence; van Heteren, Sytze; Hollis, Julie; Poyiadji, Eleftheria; Čápová, Dana; Tulstrup, JørgenABSTRACT: Open access to harmonised digital data describing Earth’s surface and subsurface holds immense value for society. This paper highlights the significance of open access to digital geoscience data ranging from the shallow topsoil or seabed to depths of 5 km. Such data play a pivotal role in facilitating endeavours such as renewable geoenergy solutions, resilient urban planning, supply of critical raw materials, assessment and protection of water resources, mitigation of floods and droughts, identification of suitable locations for carbon capture and storage, development of offshore wind farms, disaster risk reduction, and conservation of ecosystems and biodiversity. EuroGeoSurveys, the Geological Surveys of Europe, have worked diligently for over a decade to ensure open access to harmonised digital European geoscience data and knowledge through the European Geological Data Infrastructure (EGDI). EGDI acts as a data and information resource for providing wide-ranging geoscience data and research, as this paper demonstrates through selected research data and information on four vital natural resources: geoenergy, critical raw materials, water, and soils. Importantly, it incorporates near real-time remote and in-situ monitoring data, thus constituting an invaluable up-to-date database that facilitates informed decision-making, policy implementation, sustainable resource management, the green transition, achieving UN Sustainable Development Goals (SDGs), and the envisioned future of digital twins in Earth sciences. EGDI and its thematic map viewer are tailored, continuously enhanced, and developed in collaboration with all relevant researchers and stakeholders. Its primary objective is to address societal needs by providing data for sustainable, secure, and integrated management of surface and subsurface resources, effectively establishing a geological service for Europe. We argue that open access to surface and subsurface geoscience data is crucial for an efficient green transition to a net-zero society, enabling integrated and coherent surface and subsurface spatial planning.
- Pan-European geological data, information, and knowledge for a resilient, sustainable, and collaborative futurePublication . Hollis, Julie; Bricker, Stephanie; Čápová, Dana; Hinsby, Klaus; Krenmayr, Hans-Georg; Negrel, Phillippe; de Oliveira, Daniel Pipa Soares; Poyiadji, Eleftheria; van Gessel, Serge; van Heteren, Sytze; Venvik, GuriABSTRACT: Many fields of research relevant to climate-change-related policy are grounded in geological sciences – far more than is generally recognised by the public or policy makers. These fields include management of marine environments, urban development, groundwater, landslide risk, understanding the geochemistry of soils and water, and securing raw materials. Through the concerted collaborative efforts, over many years, of EuroGeoSurveys – the Geological Surveys of Europe – national datasets bearing on these and other areas have been harmonised at European scale and delivered through an online digital platform, the European Geological Data Infrastructure. This vast store of baseline data, information, and knowledge is crucial for informed pan-European decision making and is considered the core of a future Geological Service for Europe.
