    • Authors: Emma Petrella; Alessandro Chelli, Roberto Valentino
      Abstract: [One of trickiest issues in Rwanda has always been linked to hydrogeological risk. To make the scenario even more complicated, it is the lack of integrated knowledge of different disciplines that are related to landslide phenomena. In this context, the Erasmus+ EnRHEd project has organized a Summer School entitled “Landslides and Slope Stability Analysis in Rwanda” addressed to Civil Engineers and Geologists, as well as Technicians and Teachers. The summer school took place from 11 to 16 July 2022 in Musanze, Rwanda.] [In Italian]

  • Study of dilution processes of sulfidic aquifer hosted by the Fiume-Vento
           karstic complex, Frasassi (Central Italy)

    • Authors: Riccardo Nicolini; Lucio Di Matteo, Sandro Galdenzi, Fabio Baldoni, Francesco Frondini, Daniela Valigi
      Abstract: Sulfuric acid caves are widespread worldwide. In Central Italy, the Fiume-Vento karstic complex represents the most important active hypogenic cave system hosting several interconnected lakes where groundwater moves towards sulfidic springs emerging along the Sentino Stream. Stratification and dilution phenomena between freshwater and sulfidic water occur in many underground lakes, even if they remain still open if these processes are driven by stream-aquifer interaction or dripping water. The speleological knowledge coupled with geochemical surveys can help study groundwater circulation in the karst system’s inner and outer portions. The geochemical analyses on water samples taken along the Sentino Stream, inside the caves (dripping and lakes water) and in sulfidic springs allow establishing the origin of the dilution water in the dripping water. However, stream-aquifer interactions cannot be excluded during flood events. Using the tracer masse balance method (chloride and sodium ions), the discharge of the sulfidic springs ranges between 65 and 11 L/s. The results presented in this study may help understand groundwater circulation and dilution phenomena in other karst systems characterised by sulfuric acid speleogenesis type.

  • Climate impact assessment to the groundwater levels based on long
           time-series analysis in a paddy field area (Piedmont region, NW Italy):
           preliminary results

    • Authors: Elena Egidio; Manuela Lasagna, Susanna Mancini, Domenico Antonio De Luca
      Abstract: The analysis of the time-series of groundwater level are extremely important to observe the behaviours of groundwater over time and to identify any critical situations. The studied area is an agricultural district characterised by paddy fields, located in the eastern part of Piedmont, on the border with Lombardy. In this area long time-series of groundwater level, starting from the 1960s, have been collected in 16 wells. Water table data have a good completeness (in the majority of the cases >90%). Firstly, the groundwater hydrodynamic behaviour, based on water table levels, was investigated to highlight the response of groundwater to the recharge. A basic statistical analysis was performed (mean, median, standard deviation, maximum, minima), and then trends of water table levels were evaluated in order to better observe the long-term behaviour of groundwater. These analyses allowed to observe a groundwater hydrodynamic behaviour characterised by a repeating annual pattern (minimum in February/March and maximum in August/September) in correspondence to the period of irrigation. Moreover, trend analysis highlighted the presence of both wells with a decreasing water table (with maximum lowering of 4.3 m in 60 years) and wells with an increasing water table (with maximum rises of 2.8 m in 35 years). Furthermore, in most cases, it can be observed that all three trends analysed agree on being positive or negative. Future insights will be the comparison of these long time-series with the meteorological data, and the investigation of other factors (e.g. anthropic withdrawal, variations of cultivation practices and irrigation, geology of the subsoil) to better understand the causes of the water table fluctuations and trends.

  • The Nationwide Water Budget Estimation in the light of the New
           Permeability Map of Italy

    • Authors: Giovanni Braca; Martina Bussettini, Rossella Maria Gafà, Gennaro Maria Monti, Lucio Martarelli, Angelantonio Silvi, Francesco La Vigna
      Abstract: The hydrological budget is one of the fundamental tools for the sustainable management of water resources. In the last decades, the knowledge of the distribution of freshwater resources in space and time is becoming of great concern due to the growing pressure related to increasing population, water pollution, and climate change. Furthermore, in the scope of hydrological balance, the estimation of aquifer assumes particular concern in Italy. In fact, more than 80% of water withdrawal for domestic and drinkable use is derived from groundwater. In this context, the Italian Institute for Environmental Protection and Research (ISPRA) has developed a mathematical model for estimating the hydrological budget components at a national and macro-regional scale called BIGBANG. The aquifer recharge is estimated as a percentage of the monthly soil water surplus by the potential infiltration coefficient defined as a function of the permeability of the hydrogeological complexes beneath the soil layer. In this paper, a comparison highlighting the differences between the estimations of the long-term annual average of two of the main hydrological budget components, aquifer recharge and surface runoff, at national and sub-national levels, is carried out. The estimations are based on the new and more detailed Permeability Map of Italy produced by ISPRA and on the old map of the hydrogeological complexes currently used at national level used so far in the BIGBANG budget model.

  • Investigating the feasibility of using precipitation measurements from
           weather RaDAR to estimate potential recharge in regional aquifers: the
           Majella massif case study in Central Italy

    • Authors: Diego Di Curzio; Alessia Di Giovanni, Raffaele Lidori, Frank Silvio Marzano, Sergio Rusi
      Abstract: Rain gauge spatial sparsity and temporal discontinuity of data represent one of the major issues for reliable recharge estimations. In the past decades, the use of ground-based microwave weather RaDAR has dramatically improved quantitative rainfall estimation by providing spatially continuous estimates of rainfall over an area of more than 400 km2 every 10 minutes. Furthermore, weather RaDAR data have also proved relatively reliable in mountainous areas. These paramount features of RaDAR-derived precipitation data could improve the estimation of potential recharge of aquifers, which rely on geospatializations (e.g., Thiessen polygons) of rainfall data collected by a sparse rain gauge network which often shows lacking at high altitude (i.e., recharge areas), introducing additional uncertainty in the inflow volumes. Weather RaDAR rainfall estimation is also affected by various sources of error, which can be reduced by proper post-processing; however, uncertainties remain, especially for surface rain rate estimations. Despite the currently necessary complex numerical processing, the purpose of the study is to evaluate the use of the weather RaDAR data as an alternative or in addition to meteorological data. Based on the above considerations, the feasibility of using RaDAR-based precipitation data to estimate aquifer potential recharge and calculate a detailed water budget in the areas characterized by high elevations, such as the Majella massif in the central Apennines, has been evaluated. To address this objective, the water budget has been calculated in the 2017-2018 period using both RaDAR-based precipitation data and rain gauge data, as well as adopting different methods (i.e., Turc and Thornthwaite). Although intrinsically uncertain, the RaDAR-based precipitation data provided solid results, pointed out by comparing it with water budget obtained by rain gauge data, and especially with experimental literature data. This interdisciplinary work may pave the way for continuous monitoring of aquifer potential recharge at extremely high temporal and spatial resolution.

  • [Future regulation for the reduction of PFAS pollution in aquifers and for
           the improvement of drinking water quality]

    • Authors: Angelo Merlin; Andrea Sottani
      Abstract: [This Technical Note, inspired by some recent international scientific contributions, focuses attention on the relationships existing between the diffusion of per- and polyfluoroalkyl substances and the drinking water environmental sector. Firstly, the analysis takes into consideration published data to highlight the ubiquity of PFAS in the aquifers of various nations. There are also some health implications resulting from the exposure of individuals to PFAS following the ingestion of contaminated water. The technical background is then compared with the current state of the regulatory framework, indicating the reasons, collateral initiatives and precautionary criteria that must guide an urgent and effective remodeling of the law.] [In Italian]
