“…Fluoride amounts suggest that thermal waters interacted with the granitic basement under the Mesozoic sedimentary spread. Fluoride is absorbed into the water by these formations (21,34) . The cation and anion data points towards the presence of meteoric signature in the waters and the waters seeped to the surface after attaining boiling point due to meteoric activity (35,36) .…”

“…In Schoeller's chart, major cations and anions are plotted on the horizontal axis having equal divisions and the vertical scale is the logarithmic scale of an equal concentration of these ions. To envisage the relationship between two ions points are connected by polyline and the slope of the line between two ions can be equated with other samples (21) . As seen in Figure 19, as compared to the other samples, the water sample from A01 has the largest concentration of K, Mg, Ca, Na, Cl, SO 4 , and HCO 3 .…”

“…Plotting of major cations and anions in this tri-linear diagram can give an understanding of the hydrochemical evolution of hot spring water. The Piper plot contains two split tri-linear plots they are cations and anions respectively comparative concentration of each other (21) . Out of four locations, three locations in Dholera show high Cl concentrations.…”

Objective: This study is aimed at interpreting geochemical and geophysical data of 4 locations in Gujarat, India to understand the subsurface geothermal hotspot locations. Methods: CG-5 gravimeter was used to collect the gravity data. Data corrections were done to obtain a complete Bouguer anomaly. The depth of the dense bodies was calculated using Euler deconvolution. Also, the geochemical classification of physiochemical properties of geothermal spring waters of the locations was evaluated to assess their possible applications. Findings: In the sample region, the complete Bouguer anomaly analysis ranges between 1.99 mGal-2.23 mGal. The Euler deconvolution produced depth solutions ranging from 100 to 450 meters, which were mostly found near gravity highs, and the presence of deep structures can be deduced. These deep structures are translated as dense intruding bodies trapped by an overlying cap rock. The Geochemical analysis was done of the four samples. Based on the results of various plots such as Ternary, Durov, Piper, Stiff, the waters are graded as cationic with Na+K and anionic with Cl+SO 4 . The sample waters indicate suitability for drinking and irrigation at some locations. Finding these hotspots and exploiting them is of importance for these areas which are dealing with the acute water crisis. Novelty: Euler deconvolution of gravity data was first time applied for subtle geothermal trap identification in Saurashtra and Cambay basins. It has been established through this study that surface manifestation of these subtle traps are the hot springs. Systematic geochemical characterization of the hot springs progressed the nascent geothermal energy research of India.

“…The importance of energy supply and the progress towards the conversion of the worldwide energy supply system by means of renewable sources is a reality of today [1]. The awareness of a sustainable world that leaves fossil fuels aside in a transition to clean and less polluting energies opens up a range of possibilities for a study of this type of energy, in many cases with a long research trajectory [2,3] and in others with a shorter history [4][5][6].…”

Environmental Impact Comparison of Geothermal Alternatives for Conventional Boiler Replacement

In the transition towards a sustainable world with a “green horizon” (something that is also of great importance to the policy of energy self-sufficiency in housing and self-consumption), geothermal energy is seen as quite a feasible alternative for single-family homes. This article focuses on a comparison between the environmental impact and life cycle analysis of three alternatives and provides a base case for the replacement of a conventional type of boiler with a geothermal one for a typical house located in a Mediterranean climate. The first alternative (A) consists of a horizontal catchment system through a field of geothermal probes. The second alternative (B) is a shallow water catchment system, open type, with the return of water to a nearby river. The third option studied (C) is also a shallow water catchment system but with the water, return injected into a well downstream to the underground water flow. The study shows that alternatives A and B have the least environmental impact in most of the categories studied. The total amortization periods for the three alternatives and the base case differ by almost two years, with alternative A taking 6.99 years and alternative C costing 8.82 years.

“…Since each energy source is related to reasonable accessibility, and the meteorological and pedoclimatic conditions of a specific area, one of the future opportunities for Mediterranean Countries could be the choice of appropriate sustainable energy sources. According to Abdelkareem et al (2018) and Shah et al (2018) [118,119], globally, there are only 131 desalination plants powered by renewable sources, and this…”

According to the United Nations (2020), since the 1980s, the global overall rate of water use has grown by 1% per year, and it is projected that, by 2050, humanity’s water footprint could exceed 30% of current levels. This situation is in stark contrast to the path toward the Sustainable Development Goals, especially Goal 6, “clean water and sanitation”, which also influences Goal 14, “life below water”, and Goal 15, “life on land”. This is because the availability of water directly affects the food security and production capacity of each Country, and therefore its management is a crucial issue worthy of particular attention. Problems related to water security are particularly evident in the Mediterranean area, which is already facing high environmental challenges. It is an area severely affected by global warming; thus, it is one of the most vulnerable environments to climate change globally. It follows that the improper management of water resources could further worsen an already alarming situation. This research aims to study the main water-related challenges that Mediterranean Countries face, highlighting the significant problems that weaken each Country. In this regard, the indicators relating to Goal 6 were considered, to define each Country’s current state. However, for a correct understanding, the main problems these Countries face were researched through a critical review of the literature (Scopus, Google Scholar, Web of Science). In this way, we were able to underline the effects of human activities on the hydrosphere and the repercussions on various ecosystems, following the drivers-pressures-state-impact-response causal framework. The results suggest that there is still a long way for Mediterranean Countries to progress toward Agenda 2030, as they face problems related to chemical (nitrate, microplastics, heavy metals, pesticides, etc.) and biological (E. coli and other microorganisms) pollution, as well as saline aquifers, absent or obsolete infrastructures, and transboundary basins. Hence, this study aims to provide valuable tools for a better evaluation of water management in Mediterranean Countries.
