“…Additionally, the sodiumchloride composition is consistent with the groundwater type of AP1 and AP2. Since these wells are deep, water-rock interaction is favored, increasing the salinity of the water [29]. There are two scales, groundwater, and surface water*.…”

Desalination using reverse osmosis (RO) systems is one of the water technologies introduced to address freshwater scarcity in arid and semi-arid regions through the production of water with characteristics for human consumption. The Zapotal River Basin located in Santa Elena, Ecuador, is a semi-arid area, where water demand is greater than available water sources. The objective of this research is to design a decentralized RO system to production of water for consumption purposes, in terms of low salinity content. Therefore, a water sampling campaign was carried out in the study area to identify the communities with the greatest need for water desalination. Additionally, physicochemical water parameters and the analysis of major ions in surface and groundwater samples were measured to design a RO desalination system. An open-source software named "WAVE" was used to determine the removal efficiencies and energy consumption. Synthetic water solutions using NaCl electrical conductivity (EC)concentrations ranging from 3000 to 24000 μS/cm were used as feed water for the RO technology to simulate the measured EC of the study area. The experimental removal efficiency results were 95.98 and 99.52%, with an energy consumption of 3.90 -4.58 𝒌𝑾𝒉/𝒎 𝟑 . The energy consumption was optimized by increasing the number of membranes in the RO plant simulation. Finally, the importance of this study lies in designing and proposing a brackish water treatment alternative to assure the availability of water for human consumption and its sustainable management, reaffirming what is stated in SDG 6.

Karst groundwater is the main source of water supply for ecosystems that are dependent on its discharges, such as wetlands, which are habitats for various species. Due to their characteristics and significance, it is imperative to conduct research aimed at elucidating the mechanisms governing the water quality and quantity in ecosystems reliant on karst groundwater discharges. The karstic systems are susceptible to contamination, and despite this fact, there is a dearth of information available, which hampers the accurate determination of water quality. The site study is the karst groundwater system discharging in the RAMSAR wetland Ciénaga de Tamasopo (Mexico) affected by the water extraction for the extensive sugar cane agriculture. The goal was to identify the groundwater flow systems discharging into the wetland by using hydrogeochemical and isotopic techniques. Additionally, it aimed to assess the temporal changes in physical and chemical parameters. It was determined that the chemical composition of the water changes with respect to residence time in the subsoil, and the predominant processes are the dissolution–precipitation of calcite, dolomite, and gypsum by water-rock interaction, mixing, and evaporation. This study facilitated the development of a conceptual model for understanding the movement of groundwater in karst systems in a warm, sub-humid climate. This conceptual model is crucial for enhancing water management strategies in the area.
