“…Another study [13] determined that weathering of rock forming minerals and contributions from anthropogenic activities were the main processes influencing the groundwater quality in semi-arid China. Various studies in semi-arid regions concur with these findings [14][15][16][17]. Varying techniques were applied in various studies to understand hydro-geochemical processes influencing groundwater quality across the world in the last decade [18][19][20][21][22][23].…”

Groundwater is often the main or only source of fresh water supply in arid to semi-arid rural areas owing to decreasing rainfall patterns, reduced availability of surface water and socioeconomic activities. It is important to understand the hydro-geochemical processes influencing groundwater quality for improved management and sustainability of resources and to improve rural livelihoods. To understand the hydro-geochemical process influencing the hydro-geochemistry of the Soutpansberg region, this study assessed groundwater quality data from 12 boreholes and 2 geothermal springs collected between 1995 and 2017. This study indicated that the majority of the samples were classified as fresh groundwater dominated by Ca-HCO3 and mixed Ca-Mg-Cl types. Gibbs diagrams, Pearson correlations, bivariate plots and saturation indexes suggested that rock dominance processes, such as weathering of silicates, dissolution of carbonates and halite minerals and ion exchange processes, were the main hydro-geochemical processes influencing the groundwater quality in the Soutpansberg region. The high concentration of F− in the geothermal spring was attributed to the dissolution of fluorite mineral. Point source anthropogenic inputs from fertilisers were attributed to the high concentration of NO3− in the groundwater. This study recommends that research outputs should be used to influence and support policy change and groundwater allocation in arid to semi-arid rural environments for improved management of resources and livelihoods. This study further recommends that suitable deflouridation and denitrification techniques be applied to improve the quality of groundwater for drinking purposes.

“…In contrast, if CAI 1 and CAI 2 are negative, the Ca 2+ and Mg 2+ in groundwater have been exchanged by K + and Na + . Finally, if CAI 1 and CAI 2 are 0.00, the ion exchange reaction has not occurred in groundwater [49,50,56,57]. Moreover, the larger the CAI 1 and CAI 2 values, the stronger the ion exchange reaction.…”

There has been substantial research on the sources and geochemical processes associated with fluoride (F -) in agricultural groundwater. However, the spatial distribution, geochemical behaviours, and enrichment mechanisms of fluoride in the groundwater from a coal-mining district used for drinking water supply have not been fully understood. In this study, 42 drinking water samples of the groundwater were collected in May 2019 and March 2020 from the Sulin coal-mining district, Anhui, China. Samples were analysed to investigate the distribution, geochemical behaviour, and formation mechanisms of fluoride. The Fconcentrations in the groundwater samples ranged from 0.55 to 2.06 mg/L, with a mean value of 1.16 mg/L. The Fconcentrations in 54.76% of the water samples exceeded China's national standards (1.00 mg/L). The results show that the Fin the water was enriched in an environment with high pH and HCO 3 content. The weathering of Fbearing minerals was the main source of Fin the drinking water supply. Evaporation, cation exchange, competitive effect, and anthropogenic activities were considered to have promoted elevated Fconcentrations in the groundwater resource. This research will aid policy development for properly managing drinking water to eliminate health problems in coal-mining districts due to excessive fluoride intake.

“…Hydrogeochemical characterization and geological information are utmost important for the efficient management of the water resources in the aquifer [33,47]. The water quality chemical data were plotted on the Piper trilinear diagram [48] in order to understand the hydrochemical facies and associated processes in the groundwater of the area under investigation.…”

“…In India, more than 90% of water withdrawal is for agricultural uses only [21]. Groundwater plays a crucial role in the socio-economic, agricultural and environmental development of a region [32,33,47]. Due to insufficient rainfall and surface water resources in the arid and semi-arid regions, people are mainly relying on groundwater for their needs [41].…”

“…Excessive agricultural practice has put continuous pressure on the groundwater resources in this region, and therefore, potential negative impacts of agricultural activities such as salinization and sodification need to be assessed in order to prevent water and soil quality deterioration. In India, various researchers have stated groundwater pollution by nitrate due to agrarian practices, soil contamination by the indiscriminate use of agrochemicals (pesticides and fertilizers) and irrigation water quality [1,2,4,33,35,38,61,65]. Uncontrolled groundwater mining, leaching of agrochemicals to the aquifers and ill agricultural practices have resulted in the pollution of the groundwater [27,61].…”

The groundwater is the main source for irrigation and other purposes in the alluvial plains of Punjab. The poor irrigational water quality affects the soil quality which interrupts the growth of plants impacting the agricultural production and can cause risk to human health, and thus, it is important to evaluate the water quality for irrigation uses in the agrarian regions. An integrated GIS-based modelling approach along with conventional water quality indices such as sodium adsorption ratio, per cent sodium, residual sodium carbonate, residual sodium bicarbonate, magnesium hazard, permeability index, potential salinity, Kelly's ratio, electrical conductivity, total hardness, pH and total dissolved solids was used to delineate the irrigation water quality suitability zones in parts of agricultural prolific Satluj River Basin. Analytical results revealed that groundwater of the study area is very hard and slightly alkaline in nature and the relative abundance order of major ions is Mg 2+ > Na + + K + > Ca 2+ and HCO 3 − + CO 3 2− > Cl − > SO 4 2− , respectively, for cations and anions. The weighted overlay technique was applied to generate the irrigation water quality zonation map, and results revealed that nearly 3.2% (117 sq. km) of the total area was not suitable for the irrigation water quality, whereas 85.2% (3076 sq. km) and 11.6% (421 sq. km) area fall under moderately suitable and suitable classes, respectively. The elevated level of some ions found in the shallower zone as compared to the deeper zones indicates that in addition to the geogenic factors (weathering and dissolution of aquifer materials) anthropogenic inputs such as ill agricultural practices, leaching from septic tanks and municipal waste are adversely affecting the groundwater system in the region. The results of US Salinity Laboratory's diagram showed that 42% groundwater samples fall in C3S1 (high salinity with low sodium hazard) category indicating the unsuitability for irrigation purpose due to high salinity hazard and cannot be used in soils with restricted drainage. The results of Piper and Durov diagrams revealed that Ca 2+-Mg 2+-HCO 3 − is the dominant hydrochemical facies with Mg 2+-HCO 3 − water type in the groundwater of the study area and hydrochemistry is controlled by both natural and anthropogenic factors. The bottom-up approach and involvement of locals can boost the management of water resources in the study area.
