Muzzillo, R.; Zuffianò, L.E.; Rizzo, E.; Canora, F.; Capozzoli, L.; Giampaolo, V.; De Giorgio, G.; Sdao, F.; Polemio, M. Seawater Intrusion Proneness and Geophysical Investigations in the Metaponto Coastal Plain (Basilicata, Italy). Water 2021, 13, 53

The Metaponto coastal plain extends about 40 km along the Ionian coast, between the Sinni and Bradano Rivers (southern Italy). During the 20th century, the increases in modern irrigation systems, land reclamation works, the overexploitation of wells, and agricultural and industrial activities have deeply modified land use and groundwater availability and quality along the plain. These modifications negatively impacted the natural systems in terms of groundwater and soil salinization, magnifying the risks due to seawater intrusion. In this study, we explored the proneness to seawater intrusion, testing a multidisciplinary approach based on hydrochemical and geophysical investigations. A significant portion of the coastal plain was selected for this purpose. A set of 49 groundwater samples was analyzed to define the chemical characteristics of the water and geoelectrical measurements were recorded along three long profiles. The geoelectrical surveys showed in detail the aquifer bottom pattern where it is deeply incised by paleovalleys, defining the main hydrostratigraphic features, as it is necessary to prevent seawater intrusion worsening. The hydrochemical data highlighted areas with higher seawater intrusion proneness. The acquired measurements show the high proneness to seawater intrusion, especially where the aquifer bottom is very deep below the sea level, also far from the coast, and the relevance of the detailed knowledge of the aquifer bottom in supporting any kind of management. View Full-Text

Sulla rivista Water (Water 2021, 13, 327) è stato pubblicato un nuovo articolo scientifico che tratta dello studio delle acque sotterranee della piana di Gioia Tauro (costa tirrenica, Calabria, Italia meridionale) in termini di idrostatigrafia e stato chimico fisico.

Il Gruppo di Idrogeologia ha sottoscritto in questi giorni una Convenzione Operativa attuativa dell’accordo quadro tra Consiglio Regionale della Puglia e Consiglio Nazionale delle Ricerche (Deliberazione n. 153/2018 dell’Ufficio di Presidenza del Consiglio Regionale della Puglia) avente come oggetto la seguente Proposta Operativa:

“Strumenti di Studio, documentazione e ricerca a supporto delle politiche regionali verso i “Sustainable Development Goals” e test-focus sulla sostenibilità del geoscambio termico”

Il tema della geotermia a bassa entalpia è cruciale quale strategia di mitigazione ed adattamento ai cambiamenti climatici.
In tale ottica, si prevede la strutturazione su base territoriale di informazioni conoscitive, ambientali e realizzative, sul tema della geotermia a bassa entalpia nelle sue diverse declinazioni ed un testing di una attività di approfondimento delle attuali conoscenze sul contesto normativo e sugli effetti degli impianti geotermici sul sottosuolo e sulle acque sotterranee.

The Maltese Islands are located in the central Mediterranean area,
on the Malta-Sicily Platform. The archipelago consists of three main
islands, Malta, Gozo and Comino, and several other small uninhabited
islets. Malta, the largest of the three islands, has an extent of 246 km2.
The aim of this paper is to describe the collaboration between CNRIRPI
and EWA (Energy and Water Agency of Malta) and the efforts to
upgrade the hydrogeological knowledge of the Malta Island, pursuing
the sustainable utilisation of groundwater resources. This will support
the water management activities for optimizing the use of Malta’s
groundwater resources. Firstly, a review of the hydrogeological
environment of the aquifer systems has been undertaken, identifying
so some important data gaps that should be filled up. The eventual
groundwater body management tool to be developed under this
collaborative initiative will enable the formulation and testing of
updated groundwater exploitation strategies. These plans ensure the
protection of the groundwater bodies from regional and localized
sea-water intrusion, whilst taking full consideration of the potential
effects of climate change, including the variability of recharge, sea
level and seawater salinity.
