“…Li et al (2019b) explored the hydrochemical evolution of groundwater and its controlling factors in Yinchuan by utilizing hydrochemical and isotope characteristics. Zhao et al (2019) applied hydrochemical and isotope characteristics to analyse the spatiotemporal evolution of groundwater in the Hangzhou Bay New Zone and evaluated its mechanism of formation and renewal capability. Therefore, combining analysis of hydrogen and oxygen stable isotopes with hydrochemistry holds signi cant potential for elucidating water-rock interactions and protecting groundwater.…”

The Yellow River irrigation area in Tumochuan Plain is one of the primary grain production areas in the middle and upper reaches of the Yellow River Basin (YRB). The groundwater in the area is bitter and salty, which significantly influences drinking water safety of residents. To investigate its chemical characteristics and material sources, we collected 12 groundwater samplings, 3 irrigation water samplings, and 1 precipitation sample during the winter irrigation period (WIP) in November 2016 and the spring irrigation period (SIP) in April 2017, respectively. We then analysed the hydrogen and oxygen stable isotopes and hydrochemical characteristics of the shallow groundwater in the study area and investigated their affecting factors by using environmental isotopes, Gibbs diagrams, Schoeller diagrams, and ion proportionality coefficient analysis. Next, we qualitatively analysed the material sources. The results show the followings: (1) The concentrations of major ions in groundwater in the SIP are generally higher than in the WIP, which may be recharged by snow melting water in the spring. (2) The average values of δD and δ18O for the groundwater are -78.0‰ and -10.3‰, respectively, in the WIP and -77.4‰ and -10.3‰, respectively, in the SIP. However, the characteristics of hydrogen and oxygen isotopes in the groundwater are almost identical in the WIP and SIP. (3) The formation of groundwater chemical constituent are controlled by evaporation concentration and lixiviation, and dissolution of evaporite and mirabilite is the most important factor. Synchronously, the formation of groundwater chemical constituent is also influenced ion exchange and human activities. The study provides effective guidance for groundwater resource development in arid and semi-arid regions.

The geographic location of Yongqing County is optimal, covering the center of the Beijing, Tianjin, and Baoding triangle. However, the economic and social development of Yongqing County in recent years has resulted in negative impacts on groundwater. Therefore, investigating the current status of groundwater chemistry in Yongqing County is of great significance to provide a useful basis for future studies on groundwater quality assessment. The aim of this study is to assess the hydrochemical characteristics and formation mechanisms of the unconfined aquifers of Yongqing County using descriptive statistical and multivariate statistical methods. In addition, ionic ratios, Piper diagram, Gibbs diagrams, and PHREEQC software were used in this study to determine the main factors influencing the hydrochemical characteristics of the unconfined aquifers. The results suggested slightly alkaline groundwater of the unconfined aquifers in the western part of Yongqing County, belonging to the fresh-brackish groundwater type. In addition, the hydrochemistry facies types in the study area are complex, consisting of four facies types, namely HCO3−−Mg·Ca, HCO3−−Na, HCO3−-Na·Ca, and HCO3−-Na·Mg. On the other hand, the main factors influencing the hydrochemical characteristics of groundwater are mineral dissolution followed by some anthropogenic pollution. Rock dominance was the main influencing factor, demonstrated by thedissolution of silicate and carbonate rock minerals. In addition, the alternating adsorption of cations occurring in the aquifer plays a non-negligible effect on the hydrochemical characteristics of the unconfined aquifers in the study area. In fact, the validation results using PHREEQC inverse hydrogeochemical simulations demonstrated consistent conclusions with those mentioned above. According to the findings obtained, the dissolution of carbonate and silicate minerals as well as Na+, K+, and Ca2+ ion exchange in the aquifer are the main factors influencing the hydrochemical characteristics of the unconfined aquifers of Yongqing County. The recommendations suggest put forward in this research are helpful to understand the formation mechanism of hydrochemistry in typical alluvial proluvial plain and provide insights for decision makers to protect the groundwater resources.
