Book Part Groundwater Arsenic in an Urban Area: Izmir’s Comprehensive Response and Remediation Blueprint(Springer Science and Business Media Deutschland GmbH, 2025) Kırçiçek, N.T.; Güngör, E.B.; Baba, A.The contamination of groundwater with arsenic poses a critical challenge to the environment and public health, affecting millions of people worldwide. In the rapidly urbanising regions of Türkiye, understanding the origin, mobility and effective treatment of arsenic contamination is crucial to ensure water safety. This study analyses the spatial distribution of arsenic contamination of groundwater, specifically in the province of İzmir, while attempting to delineate the potential sources of risk. The arsenic concentrations in groundwater samples from different districts were analysed, and the variations at district level were visualised using a point-based density map. The resulting values were then critically compared with the World Health Organization (WHO) limits and Turkish national regulations (10 μg/L) to draw attention to the pronounced spatial differences in concentrations. Following the arsenic crisis in 2008, the İzmir Municipality has taken a decisive course and implemented targeted arsenic remediation strategies that represent significant progress in solving and addressing this pervasive problem. In 2023 alone, more than 139 million m3 of groundwater were treated, accounting for almost 30% of the city’s drinking and industrial water supply. This considerable magnitude represents a remarkable level of implementation, especially against the backdrop of numerous global cities struggling with similar contamination problems. The results of this study should serve as a basis for sustainable groundwater management strategies, not only for İzmir, but also for other regions with hydrogeological and urban dynamics. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.Article Geothermal Drying in Agricultural Sector - Worldwide Examples(Elsevier Ltd, 2026) Tomaszewska, B.; Baba, A.; Akkurt, G.G.; Mukti, M.; Helvaci, H.U.; Bielec, B.; Operacz, A.Agricultural drying is traditionally used to preserve fruits and vegetables which mostly relied on energy-intensive processes usually powered by fossil fuels. In this review, we explore an innovative and sustainable alternative: using geothermal energy to dry produce. The paper reviews the main technical aspects related to the use of geothermal energy in drying fruits and vegetables. We delve into the technical details of two leading methods, hot air drying and refractive window drying, highlighting their advantages, drawbacks, and the critical factors that influence the quality of the final product. By examining real-world applications from countries as diverse as Iceland, the USA, Greece, Turkey, Macedonia, Kenya, Serbia, El Salvador, Guatemala, Mexico, Thailand, Poland, and the Philippines, this paper showcases how geothermal energy can be directly applied in drying operations—whether through standalone systems operating between 60 °C and 97 °C or integrated cascade systems wherever geothermal resources are used for power generation and in the form of the waste heat for drying purposes, can be considered as important direction. Due to a lack of actual information on the economic aspects of geothermal drying, in addition to outlining the technical merits of geothermal drying, we also discuss economic considerations and potential challenges to provide a roadmap for future projects. Moreover, the authors underlined several aspects that can contribute to the failure or limited success of geothermal drying projects. Ultimately, adopting geothermal drying not only reduces greenhouse gases (GHS) emissions but also lessens dependence on costly, polluting fossil fuels, paving the way for a greener, more energy-efficient future in food preservation. © 2025 Elsevier Ltd.

The general distribution of geothermal systems is controlled by the different types of fault systems, active volcanism, and hydrothermally altered areas. These diverse resources occur in different parts of the Earth and different geologic settings. In addition, geothermal resources may have different physical and chemical properties depending on temperature and depth variations, geology, geochemistry, and hydrogeological characteristics. These resources are used for direct (heating, cooling, greenhouse, thermal bath, and others) and indirect (electricity generation) applications. Today, geothermal heat base applications continue to develop in an integrated manner with the processes of combating global warming and adaptation to climate change. This chapter provides information on the source of geothermal energy, the current status of the geothermal energy sector, the importance of geothermal energy, the history of geothermal energy applications, and the classification of geothermal systems. © 2024 Elsevier Inc.

In order to ensure the sustainable operation of geothermal power plants, it is necessary to recharge geothermal fluids back into the reservoirs. It is worth mentioning that the accidental release of geothermal brines or the accumulation of salts and silica from geothermal power facilities can lead to significant environmental issues. Geothermal fluids brought to the surface for any application must be treated in the most practical and feasible way before discharge to the any receiving body or back to the reservoirs. The objective of this chapter was therefore to study the hydrogeochemical properties of geothermal fluids in different regions and propose some scientific approached for the treatment of spent geothermal fluid prior to its use as an alternative water source, especially in agriculture applications. © 2024 Elsevier Inc.

These energy sources can be used directly or by conversion to other forms of energy. The use of geothermal energy for various purposes such as electricity, heating, cooling, greenhouses, dry food, thermal tourism, fisheries, and mineral extraction is widespread in many countries. Today’s installed geothermal capacity is dominated by the United States with about 3.7 GW, followed by Indonesia (2.1 GW), the Philippines (1.9 GW), Turkey (1.7 GW), and New Zealand. Global geothermal power generation capacity at the end of 2020 was 15.6 GW. The top ten geothermal producers account for nearly 90% of the global market, and many countries, especially Europe, plan to invest in geothermal soon. Looking at the direct use of geothermal energy for thermal applications, only four countries (China, Turkey, Iceland, and Japan) account for three-quarters of the energy consumed. Hydrogen can provide a number of benefits for future energy systems. Hydrogen can serve as storage for intermittent renewables or provide grid services. It can replace natural gas in industrial heating processes that are otherwise difficult to decarbonise. Therefore, geothermal resources can be used to produce clean hydrogen. Within this section, the importance and use of geothermal energy have been highlighted. At the same time, detailed information is given about the importance of hydrogen, its production, and its use in connection with geothermal energy. © 2025 selection and editorial matter, Mohammad Reza Rahimpour, Mohammad Amin Makarem, and Parvin Kiani.Editorial
