- 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.
- Atlas Europeo de Potencial de Geoenergías Sostenibles: una prioridad del Servicio Geológico para Europa (GSEU) [Resumo]Publication . Canteli, P.; Herms, Ignasi; Ramalho, Elsa; Carvalho, João; Arnó, Georgina; Caldera, N.; García-Crespo, J.; Carrión, E.RESUMEN: El proyecto europeo GSEU (Servicio Geológico para Europa, 2022-2027) respalda la visión del Pacto Verde Europeo a través del conocimiento del subsuelo y en particular, de las materias primas, la energía, el agua y todas las áreas relacionadas. El objetivo último del proyecto es establecer las bases de un Servicio Geológico para Europa a través de 48 servicios geológicos nacionales y regionales de 35 países europeos – EuroGeoSurveys –, y demostrar la capacidad del mismo. Uno de los resultados de este ambicioso proyecto será el denominado “Atlas Europeo del potencial de geoenergías sostenibles”; es decir, se construirá, por primera vez, un atlas continuo a escala europea, que incluirá mapas, bases de datos del potencial evaluado para el almacenamiento geológico (CO2, H2 y CAES); para los recursos geotérmicos profundos y someros; y almacenamiento subterráneo de energía térmica (frío y calor).
- Enhancing Resilience of Hot Spring Ecosystems Towards a Model of Sustainable Management of SPA Territories, Driving Innovation and Energy transition [Poster]Publication . Bertin, C.; Iasio, C.; Herms, Ignasi; Arnó, Georgina; Carvalho, João; Ramalho, Elsa; Becerra, S.; Roussel, M.; Brut, E.ABSTRACT: The climate observation systems have classified 2020, 2022, 2019, 2015, and 2014 as the five hottest years in Europe over the past four decades. In the SUDOE region, 2022 was the warmest year since 1950. The projected long-term decline in precipitation in the SUDOE region may alter the natural properties of thermal springs, by changes in of shallow and deep groundwater mixing, impacting their anthropogenic ecosystem. Currently, there is no data assessing the impact of climate change, nor is there any adaptation strategy in place to anticipate its socio-economic consequences. Data on groundwater quality, climate change vulnerability, and territorial adaptive capacity are heterogeneous, exacerbating the economic divide. Migration movements and indirect impacts of climate change, as such as pandemic crises, may further intensify stress on water resources and the economy.
