“…Appelo and Postma (2005) [97] suggested that an IBE exceeding 5% should be considered anomalous. Li et al (2016) [74] and Bouaissa et al (2021) [98] considered test results with IBE more than 9% and 10% as accurate, respectively. In two other studies, test results with IBEs exceeding 10% were also deemed acceptable [19,99].…”

Coastal areas have made substantial contributions to global economic development but are plagued by challenges such as groundwater salinization. Groundwater serves as the primary source for drinking, industrial, and domestic purposes in these coastal areas. Therefore, understanding the causes and processes of groundwater salinization holds paramount significance for effective groundwater management. The coastal area of Laizhou Bay in northern China serves as a quintessential example of such a scenario. With substantial groundwater extraction and severe groundwater salinization issues, it exacerbates the disparity between water-resource supply and demand. Currently, our understanding of the processes and influencing factors related to groundwater salinization in this region remains limited. In this study, employing hydrochemical and stable chlorine isotope analyses on 35 groundwater and seawater samples, an in-depth investigation into the complex mechanisms underlying groundwater salinization in the Quaternary aquifers of the eastern coastal plain of Laizhou Bay was conducted. The test results of the samples indicate that brine and saline groundwater are primarily of the Na-Cl type, exhibiting a hydrochemical composition similar to that of seawater. Brackish groundwater exhibits a diverse hydrochemical composition. The hydrogen and oxygen isotope characteristics of brackish and fresh groundwater resemble atmospheric precipitation, while brine, seawater, and saline groundwater show hydrogen and oxygen isotope depletion. Compared to seawater, brine exhibits significant δ37Cl depletion. The analysis of the test results reveals that the formation of brine aquifers results from a complex interplay of climate change, tectonic movements, and sea–land evolution, involving lagoon development during seawater regression, salt concentration through evaporation, and subsequent water–rock interactions. The genesis of saline groundwater involves a complex interplay of brine–seawater mixing, significant evaporation, and potential input of fresh groundwater from atmospheric precipitation and river sources. The formation of brackish groundwater is predominantly influenced by atmospheric precipitation, and agricultural activities, with significant variations in NO3− concentrations attributed to varying intensities of fertilizer application in the northern plain area. These insights contribute to a deeper understanding of the origins of groundwater and can inform the development of policies for groundwater protection in this area.

“…Preserving the cleanliness and safety of groundwater is of utmost importance for achieving sustainable social and human development. However, due to rapid urbanization and increased wastewater generation, the deterioration of groundwater quality has become a worldwide concern, given its widespread distribution and potential health implications (Bouaissa et al 2021) (Bulut et al 2020) (Gao et al 2020) (Das et al 2019). Many cities worldwide, particularly those in arid regions, are currently confronted with the dual challenge vis-à-vis groundwater depletion and degradation of water quality ) (Liu and Li 2019) (Grimmeisen et al 2017) (Li et al 2013).…”

Groundwater in Afghanistan stands as the predominant water source employed for potable consumption, household utilization, agricultural irrigation, and industrial applications. Major cities of Afghanistan are largely dependent on groundwater resources. However, the groundwater quality of major cities in Afghanistan was not investigated in detail. In this study, we investigated Mazar-e-Sharif city of northern Afghanistan intending to identify the major hydrogeochemical processes controlling groundwater chemistry and evaluate the groundwater quality of Mazar-e-Sharif using an integrated approach. We found that 1) The prevailing groundwater within the study area are predominantly characterized by Na-(Ca)-HCO3 and Ca-(Mg)-SO4 water types. 2) Physicochemical variables such as NO3¯, F¯, TDS, and SO42− exceeded the World Health Organization (WHO) safe limits in many wells. 3) Weathering of silicates and cation exchange are the main hydrogeochemical processes controlling hydro-geochemistry in the aquifer. 4) The high salinity observed in the groundwater of Mazar-e-Sharif is likely attributed to a combination of geogenic and natural factors and the Cl/Br ratios suggest that salinity may originate from evaporitic lacustrine and evaporite deposits. The findings of this study hold value for decision-makers in formulating a proficient strategy for the management of groundwater resources in Mazar-e-Sharif City in achieving the UN sustainable goal (SDG) of providing sustainable water for all.

Groundwater is an indispensable source of water for drinking water supply, agriculture and industry worldwide. In arid and semi-arid regions, groundwater has seriously deteriorated in recent decades due to environmental changes, anthropogenic activities and marine intrusion. A total of 79 groundwater samples from the Nekor-Ghiss plain were sampled for major chemical ion analysis. These analyzes showed that the water samples were highly mineralized (>1,500 mg/L), with hardness (83.5% of the samples were very hard) and high concentrations of chemical elements, such as Cl−, Mg2+, Na+ and SO42-. To assess the quality of water in the study area for irrigation and consumption purposes, we used the quality index (GWQI) as well as a multi-criteria analysis based on “geographic information system” by assigning a weight to the different water quality parameters. Also, Piper and Durov diagram was investigated. The results of the study were focused on the water quality parameters of the collected groundwater samples, such as the sodium adsorption rate (SAR), the percentage of soluble sodium (Na%), the Residual Sodium Carbonate (RSC) and Permeability Index (PI) Majority of water samples in the study area are suitable to be used for irrigation. Magnesium Risk (MH) and Kelley’s Ratio Kelly ratio. 51.9% unsuitable samples to 59.49% good samples for irrigation purposes. Monitoring the quality and quantity of groundwater is crucial for the effective and sustainable management of this valuable resource. According to the results obtained, it appears that 92% of all the samples are located in the domain of frequent recharge waters of limestone and dolomitic aquifers, namely, Ca-Mg-HCO3. About 8% of the samples measured have a composition of the Ca-Na-Mg-HCO3 type.
