“…The dissolution and weathering of calcite and dolomite minerals increases the concentration of bicarbonate ions in the groundwater in the Precambrian basement. A few spots in the sedimentary quaternary section of the study area show elevated levels of bicarbonate concentrations due to agricultural activities, which enhance the natural contents of bicarbonate ions in the groundwater system [78]. The concentration of chloride (Cl − ) and sulfate (SO 4 2− ) in the groundwater of the KYB varies from 0.7 to 372 mg/L, with a mean concentration of 48 mg/L, and from 0.1 to 133 mg/L, with a mean value of 15 mg/L, respectively (Table 2).…”

The assessment of hydrochemical characteristics and groundwater quality is crucial for environmental sustainability in developing economies. This study employed hydrogeochemical analysis, geospatial analysis, and groundwater quality index to assess hydrogeochemical processes and quality of groundwater in the Komadugu-Yobe basin. The pH, total dissolved solids (TDS), and electrical conductivity (EC) were assessed in situ using a handheld portable electrical conductivity meter. The concentrations of the major cations (Na+, Ca2+, Mg2+, and K+), were analyzed using inductively coupled plasma optical emission spectroscopy (ICP-OES). The major anions (chloride, fluoride, sulfate, and nitrate) were analyzed via ion chromatography (IC). Total alkalinity and bicarbonate were measured in situ using a HACH digital alkalinity kit by the titrimetric method. Hydrochemical results indicate some physicochemical properties of the groundwater samples exceeded the maximum permissible limits as recommended by the World Health Organization guidelines for drinking water. Gibbs diagrams indicate rock–water interaction/rock weathering processes are the dominant mechanisms influencing the groundwater chemistry. Groundwater is predominantly Ca2+-Mg2+-HCO−3 water type, constituting 59% of the groundwater samples analyzed. The groundwater quality index (GWQI) depicted 63 and 27% of the groundwater samples as excellent and good water types for drinking purposes, respectively. This study further relates the interaction between geology, hydrochemical characteristics, and groundwater quality parameters. The results are essential to inform a sustainable management strategy and protection of groundwater resources.

“…A detailed assessment of groundwater quality for drinking and irrigation near the Rooppur Nuclear Power Plant in Bangladesh was described in the article by Uddin et al (2023). The research area was subject to the water monitoring guidelines as landfills, so research conducted at such a facility can be considered a good example of using the described index.…”

Correctly assessing the impact of waste landfills on groundwater quality requires the development and use of comprehensive tools that consider the content of individual components in water, as well as those relating to the hydrochemical background. The article presents a comparative analysis of selected water quality indices used around the world to assess the environmental threat caused by sources of pollution. The paper includes the following indicators: Water Quality Index, Landfill Water Pollution Index, Nemerow Pollution Index, Backman Index, Canadian Water Quality Index, Horizontal Ratio, Enrichment Factor and Fuzzy Water Quality. Attention was paid to the values of individual indices, their applicability in municipal and industrial waste landfills, and limitations in their use. A literature review has proven that some indices, such as the Landfill Water Pollution Index and Nemerow Pollution Index, are used very often as they provide reliable results. Index methods help conduct rational water management, complement groundwater quality monitoring, and serve as a tool for making decisions in various water protection areas.

“…The overexploitation declined the groundwater level from 40 to 80 m below the ground surface from 1967 to 2007 (Mekkawi et al, 2017). Hydrological, atmospheric, climatic, topographical, and lithological factors are all natural influences on groundwater quality (Islam et al 2017;Mukate et al, 2020 andUddin et al, 2023). In the last decades, the groundwater quality of the NSA has been degraded due to high groundwater abstraction and declining water levels.…”

roundwater in the Kharga Oasis, located in the Western Desert of Egypt, is an essential resource for the local population. The Oasis is fed by the Nubian Sandstone Aquifer (NSA) of the Cretaceous age. This aquifer is one of the world's largest reservoirs, which provides fresh water for drinking, irrigation, domestic use, and industrial purposes. The NSA possesses four bearing zones; Zone A, Zone B, Zone C, and Zone D, which are separated by clay confining layers. The total penetration depth ranges from 12.5 to 800 meters, and the aquifer is underlain by granitic and basement rocks. The groundwater temperature ranges between 18 to 36.8°C, where high temperatures have been detected in the deeper zones (C and D), indicating geothermal activity. Generally, the quality of NSA water is fresh to brackish water types; however, the deeper aquifer zones (C and D) mainly contain freshwater. The concentrations of the trace elements and the natural radioactive nuclei (Rb, Pb, 232 Th, 238 U, and Sr) in the NSA waters are insignificant and far below the permissible drinking limits, and they are mainly coming from the geogenic source due to leaching of aquifer matrix. The stable isotopes (δ 18 O and δ 2 H) show great insights for recharge and salinization sources. The δ 18 O ranges from -11.96 to -6.11‰, while δ 2 H ranges between -83.5 to -67.7‰, indicating that the groundwater in the NSA is fossil water (paleometeoric origin) as the aquifer was recharged during the paleo heavy pluvial periods. Accordingly, the groundwater in Kharga Oasis is a paleo nonrenewable resource whose quality has been threatened mainly by geogenic natural pollution, agricultural activity, and overexploitation.
