“…Among the anions, Cl − and SO4 2− continued to increase in varying degrees, whereas HCO3 − decreased slightly, showing that groundwater dissolved rock salt and gypsum during the flow process, accompanied by weak evaporation [6,10,44]. In general, the groundwater in the study area showed typical regional groundwater recharge characteristics of high HCO3 − and Ca 2+ , low TDS and weak alkaline pH [6,34,43]. Gibbs diagrams [27] were used to represent the relationships between anions [Cl/(Cl+HCO 3 )] and cations [Na/(Na+Ca)] and TDS in groundwater samples.…”

“…As the surface elevation decreases, evaporation increases. The main concentrations of human habitation and industry occur on the loess and river terraces, resulting in higher degrees of anthropogenic influence on groundwater [10,19,43]. The Wilcox plots show that differences in the sample distributions are similar to the USSL.…”

“…The HCO 3 •SO 4 -Ca•Mg and HCO 3 •SO 4 •Cl-Ca•Mg type samples had a patchy distribution, mostly concentrated in human settlements and industrial production areas. This suggests that fecal emissions from humans and animals may be one driver of the increases in Cl − and SO 4 2− concentrations [42,43]. From west to east, the type of water chemistry gradually changed from HCO 3 -Ca to HCO 3 -Na and HCO 3 •SO 4 -Ca•Mg.…”

While irrigated crops produce much higher yields than rain-fed crops, the ionic components of irrigation water have important effects on crop yield. Groundwater is widely used for irrigation in the Baojixia irrigation area in China. The chemical characteristics and water quality of groundwater in the Baojixia irrigation area were analyzed and evaluated to study the impact of groundwater quality on crop yield. Results showed cations in the groundwater to mainly be Na+, Ca2+, and Mg2+, whereas the anions are mainly HCO3−, SO42−, and Cl−. Water-rock interaction and cation exchange were identified as the main factors affecting hydrogeochemical properties from west to east. The study found salinity and alkalinity of groundwater in the western region of the study area to be low, and therefore suitable for irrigation. Groundwater in the eastern part of the study area was found to have a medium to high salinity and alkalinity, and is therefore not recommended for long-term irrigation. The groundwater irrigated cultivation of wheat and corn in the research area over 2019, for example, would have resulted in a drop in the annual crop output and an economic loss of 0.489 tons and 0.741 × 104 yuan, respectively. Irrigation using groundwater was calculated to result in the cumulative loss of crop yields and an economic loss of 49.17 tons and 80.781 × 104 yuan, respectively, by 2119. Deterioration of groundwater quality will reduce crop yields. It is recommended that crop yields in the study area be increased by strengthening irrigation water management and improving groundwater quality.

“…Excessive groundwater pumping has also been linked with a deterioration in groundwater quality due to vertical leakage through aquitard in multilayer aquifer systems . Since groundwater quality in arid and semiarid areas is intimately linked to socioeconomic development, it is imperative to assess it. − In order to determine the causes of groundwater quality decline and offer sustainable groundwater management alternatives, studies on groundwater quality assessments have emerged as a topic of interest for academics around the world. − Nitrate and fluoride pollution in groundwater is a global concern due to its adverse impact on human health. , Agriculture-related activities cause the inorganic compounds present in fertilizers to enter bodies of surface water and groundwater, increasing the nitrate content in the water, which then returns to the soil through irrigation . Nitrates can harm human health by causing methemoglobinemia, thyroid problems, or cancer, as well as irreversible damage to the aquatic system. , Arid and semiarid regions globally have been associated with fluoride pollution. − Fluoride enters the human body mostly through drinking water .…”

The present study was carried out in the Harrat Khyber region of the Madinah province in Western Saudi Arabia. The objective of the study was to determine the main factors affecting groundwater chemistry and assess the impact of groundwater quality on human health with respect to nitrate, fluoride, and heavy metals (arsenic, chromium, copper, nickel, selenium, and zinc). Hydrochemical data for 70 groundwater samples from dug wells and bore wells from Harrat Khyber were interpreted to achieve the research objective. The groundwater chemistry is influenced by ion-exchange and the evaporation process. A wide variation in the concentration of various major ions is observed primarily due to the varied nature of the aquifer system which includes the unconsolidated wadi deposits, weathered-fractured basaltic aquifer system, and subbasaltic sedimentary aquifer system. The total hazard quotient (THQ) with respect to NO 3 and F was determined. Although the F values are well within the limits of human consumption in water prescribed by WHO, the values of NO 3 exceed the allowable limits in 50% of the groundwater samples. The average THQ values are 2.16, 2.92, and 2.34 for adults, children, and infants, respectively, which makes the water unsafe for human consumption. Six heavy metals (arsenic, chromium, copper, nickel, selenium, and zinc) were used to calculate the heavy-metal contamination index (HCI). The average HCI value is 19.505. Overall HCI calculation shows that the groundwater is unpolluted with respect to heavy metals. The heavy metals in water are mainly of geogenic origin.
