“…Sodium percentage (%) varied from 18.56 to 67.06, with a mean of 34.98%. The groundwater was classified according to the standard classification of Na + (%) ( Table 3) [17,30]. A total of 71% of the groundwater samples belong to the category of "Good", while 27% of the samples fall in "permissible" to "doubtful" category.…”

Groundwater resources are playing an increasingly vital role in water supply for domestic and irrigation purposes in the Yinchuan Plain, along with the reduction in water transfer from the Yellow River. This study aimed to identify the current status of phreatic water quality and associated hydrogeochemical processes in an irrigated region along the upper Yellow River. A total of 78 water samples were collected in September 2018 for chemical analysis. Results showed that the phreatic water was excellent or good in most areas west of the Yellow River, while it was poor or very poor quality in some places east of the Yellow River. The nitrate contamination is particularly severe in the pluvial-alluvial plain, relating to the localized fine-grained zone with low permeability. Most samples had no sodium hazard but had magnesium hazard. Additionally, the overall evolutionary trend of the phreatic water showed the transformation of Ca-Mg-HCO 3 into Na-Cl-SO 4 type. Rock weathering and evaporation jointly predominate the evolution of phreatic water chemistry. The main geochemical processes involve the dissolution/precipitation of gypsum, halite, dolomite. and calcite, along with the cation exchange. Insights from this work have important implications for groundwater sustainable management in such irrigated regions along the upper Yellow River.

“…Groundwater quality is primarily influenced by the aquifer rock mineral and recharge pathways (Kohlhepp et al 2017;Liu et al 2017;Gu et al 2017;Kumar et al 2019). As water passes through its recharge pathways from recharge to discharge points, several other types of hydrogeochemical processes alter its physical and chemical properties and in some aquifers, water may be unsuitable for drinking and agriculture (Abd El-Aziz 2017;Dehnavi et al 2011;Farid et al 2017). At least, one-third of the global population rely on groundwater for drinking (Panaskar et al 2016).…”

Hydrochemical characterization of shallow and deep groundwater in Basement Complex areas of southern Kebbi State, Sokoto Basin, Nigeria

Groundwater under Basement Complex areas of southern Kebbi has been characterized in order to determine its suitability for drinking and irrigation use. Water samples were drawn from shallow groundwater (hand-dug shallow wells < 5 m) and deep groundwater (boreholes > 40 m). Physical parameters (i.e., temperature, TDS, pH, and EC), were determined in situ, using handheld meters. Discrete water samples were obtained for determination of chemical parameters. Results from severalsample ANOVA (Kruskal-Wallis test) suggested that heterogeneity in water table appeared to exert significant influence on groundwater chemistry which is characterized by a significant difference in pH, EC TH, Na + , Zn 2+ , Mg 2+ , PO 4 3− , Cl − , HCO 3 − , SO 4 2− , and NO 3 − concentrations. Also, ions including Fe 3+ , Zn 2+ , Mg 2+ , Na + , PO 4 3− , and SO 4 2− are above World Health Organization (2011) and National Standard for Drinking Water Quality (2007) reference guidelines. Most of the groundwater sources are moderately hard. Groundwater classification based on chloride, EC, and TDS revealed water of excellent quality for all types of uses. However, groundwater classification based on nitrate pollution revealed water of poor quality. Rock mineral is the major mechanism controlling water chemistry, as revealed by the Gibbs model. Most of the water sources have positive Scholler index, indicative of overall base exchange reactions in the underlying aquifers. Such condition was well explained by Piper trilinear diagram, which revealed two types of faces: Ca-Mg-HCO 3 and Ca-Mg-SO 4-Cl. The HCA categorized wells into three groups according to their hydrogeochemical physiognomies. Despite the significant difference in ions concentration and chemical indices, groundwater composition is more influenced by rock weathering than anthropogenic inputs. Groundwater evaluation for irrigation use indicates a significant difference in SAR level which is related to poor permeability index in shallow groundwater. Higher values of Kelly's index and magnesium adsorption ratio threatened groundwater suitability for irrigation use in the study area.

“…Overall, using shallow groundwater for agricultural irrigation would give rise to a serious salinity hazard, but the degree of sodium hazard would be low. The process of salt deposition and soil salinization is mainly caused by the salinity in irrigation water, which may reduce the effective absorption of water and nutrients by plants [20]. Reasonable drainage mode and good soil permeability are needed for better agricultural irrigation and lower salinity hazards [18].…”

“…Compared with shallow groundwater, deep groundwater is less contaminated by human activities and can better play a drinking function. The quality and safety conditions of drinking water have been a public concern all over the world especially in developing countries, where many kinds of diseases are directly associated with unsanitary conditions in drinking water [3,[20][21][22]. Therefore, the evaluation of groundwater quality for drinking is significant for health [23,24].…”

Groundwater is an irreplaceable resource for irrigation and drinking in the North China Plain, and the quality of groundwater is of great importance to human health and social development. In this study, using the information from 59 groups of groundwater samples, groundwater quality conditions for irrigation and drinking purposes in an agricultural region of the North China Plain were analyzed. The groundwater belongs to a Quaternary loose rock pore water aquifer. The depths of shallow groundwater wells are 20–150 m below the surface, while the depths of deep groundwater wells are 150–650 m. The sodium adsorption ratio (SAR), sodium percentage (%Na), residual sodium carbonate (RSC), magnesium hazard (MH), permotic index (PI) and electrical conductivity (EC) were selected as indexes to evaluate the shallow groundwater suitability for irrigation. What’s more, the deep groundwater suitability for drinking was assessed and the human health risk of excessive chemicals in groundwater was studied. Results revealed that SAR, Na% and RSC indexes indicated the applicability of shallow groundwater for agricultural irrigation in the study area. We found 57.1% of the shallow groundwater samples were located in high salinity with a low sodium hazard zone. The concentrations of fluorine (F−) in 79.0% of the deep groundwater samples and iodine (I−) in 21.1% of the deep groundwater samples exceeded the permissible limits, respectively. The total hazard quotient (HQ) values of fluorine in over half of the deep groundwater samples exceeded the safety limits, and the health risk degree was ranked from high to low as children, adult females and adult males. In addition to natural factors, the soil layer compression caused by groundwater over-exploitation increased the fluorine concentration in groundwater. Effective measures are needed to reduce the fluorine content of the groundwater of the study area.
