“…Alicante and Murcia regions are located in South-eastern (SE) Spain, among the regions with the largest (structural) water deficit in Europe of around 400 hm 3 /year [36]. The climatic characteristics of the SRB, in which the study was carried out (Figure 1), correspond to a semiarid Mediterranean climate [37], and according to the water exploitation index, which is the ratio of total fresh water abstraction to the total renewable resource, reaches 130%, ranking this basin with the third highest level of water stress in Europe [38]. The coastal and pre-coastal sectors of Alicante and Murcia are highly specialized in economic activities with high water consumption, mainly residential tourism [39] under the slogan of "sun and beach" [40] and intensive agriculture with an export vocation [41].…”

Although desalination water cost and quality standards have been widely studied, less attention has been paid to understanding how desalination plant managers and irrigation communities interact to address water scarcity. This paper aims to approach these questions from experience in Alicante and Murcia (Spain). Two specific questionnaires have been applied to (1) three desalination plants managed by the Spanish public company ACUAMED, and (2) 11 irrigation communities who use desalinated seawater. Discursive analysis has been applied in order to deepen understanding on the driving factors, benefits, and barriers of desalination use and management. Results highlighted how (1) irrigation communities consider desalination as a complementary water source to be combined with conventional water resources, (2) both ACUAMED and irrigation communities highlighted two main advantages of desalination: the security/guarantee of supply and water quality parameters, and (3) managers and irrigators disagree on the desalination model of seawater provision and management, since irrigators consider that the Central Union of the Tajo-Segura transfer irrigators (SCRATS) should have a leading role. In addition, the main driving factors and barriers useful for policy makers when closing the gap of desalination have been identified: water price and energy consumption; lack of water storage capacity and regulation; environmental impacts.

“…The climate in this area is described as "steppe or sub-desert Mediterranean" according to the Köppen climate system. It is characterised by average annual temperatures above 18 • C, winters with mild average temperatures above 10 • C and hot summers with average temperatures above 26 • C [41]. On the other hand, the average annual rainfall is less than 300 mm, with rainfall basically concentrated in autumn and spring [41].…”

Mine waste constitutes one of the biggest environmental and management problems, both due to its quantity and its danger when they are rich in toxic elements. There is a wide variety of waste from the oxidation of ores in metal mining areas, both metal sulphide and other minerals. These residues may be enriched in potentially toxic elements that can spread and contaminate ecosystems, farmland and villages. This study has focused on the characterization and evaluation of residues derived from metal-bearing mining waste in abandoned mining areas. Mineralogy and geochemical characteristics were determined by XRD, WDXRF and TG-MS techniques. In addition, DIN 38414-S4 leaching tests were carried out to assess the risk and mobility of potentially toxic elements. Silicates and oxides were found as the main mineral groups, followed by sulphates. These tailings were particularly enriched in Zn, Pb, As, Sb and Cd, while their leachates had high or extreme metal content. Consequently, these mining wastes are considered toxic and hazardous, even for landfills. Sulphides, as the primary source, and sulphates from their oxidation, were the main sources of these pollutants. Sulphates, As, Zn, Cd and Cu determined the specific environmental impact of the different tailing types, which were grouped into different clusters according to their mineralogy and geochemistry. These results provided a better understanding of the environmental hazards associated with the different types of metal mining waste in the area studied.

Salt efflorescences from metal sulphides and their waste are important drivers of pollution both in and around mining areas. However, little is known about these supergene minerals, particularly in the mining areas of the Mediterranean. This study aims to characterise saline efflorescences and their leachates from a Mediterranean mining area located in Southeast Spain. The physicochemical characteristics were determined using stereomicroscopy and compositional analysis, with the following techniques: XRD, WDXRF and TG-MS. Additionally, to assess the risk and potential mobility of their analytes, the samples were subjected to the leaching test DIN 38414-S4. The results showed that the salt efflorescences presented a wide range of crystalline habits and colours. Sulphates were by far the largest mineral group, followed by silicates, oxides and sulphides. Their geochemistry was dominated by elements such as S or Fe, although other potentially toxic elements such as Cd, As, Zn, Pb, Ni and Cu were also present. Due to their high metal(loid) concentrations, the salt crusts studied may act as sources of environmental contaminants, demonstrating that their leachates pose a considerable risk to soil and drinking water quality. An analysis of the correlations and provenances of the components of the salt efflorescences revealed the possible presence of some rare supergene minerals of great interest, such as cuprocopiapite and Pb-As-jarosite.
