This study aimed to determine the hydrochemical characteristics and hydrogeochemical processes of shallow groundwater in the Jinta Basin, northwest China, and to evaluate the suitability of groundwater quality for drinking water and agricultural irrigation. A systematic hydrogeological survey was conducted in the study area from May 2017 to October 2018, during which 123 representative samples of groundwater were selected for analysis of chemical parameters and determination of the water quality index. The results showed that the pH of groundwater in the study area was weakly alkaline and ranged between 7.21–8.93. Dominant cations were Mg2+ and Na+ and the dominant anion was SO42−. Along the groundwater flow from the southwest to northeast, the dominant groundwater chemistry type in the recharge area was Mg-HCO3·SO4. After the transition of the groundwater types in the runoff area to Mg-SO4·HCO3 and Mg·Na-SO4, the groundwater type in the discharge area evolved into Na·Mg-SO4·Cl. The major factors driving the evolution of groundwater chemical types in the Jinta Basin were found to be rock weathering, evaporation and precipitation. The chemical components of groundwater mainly originated from the dissolution of silicate rock and evaporative concentration of salt under water-rock interaction, whereas the dissolution of carbonate had little influence. The quality of drinking water was divided into five groups, and 39.84% of samples fell within the high and good quality groups. The quality of agricultural irrigation water was divided into different grades according to different methods.

Methods for groundwater quality and pollution assessment are applied extensively, but it is difficult to determine a unified evaluation model. On the basis of hydrogeochemical characteristics analysis in 2016 compared with that in 1995, the five-element connection number SPA (set pair analysis) method was applied to evaluate the groundwater quality of the Gaoqiao diluvial fan under the influence of hydrogeological conditions and human activities along the flow path in our work. Descriptive statistics methods, Piper diagram, and a Schoeller diagram were also used to analyze the hydrochemical characteristics of groundwater such as chemical components, total dissolved solid, and total hardness. The change of the typical pollutant of fluorine was analyzed to evaluate the groundwater quality under the influence of human activities. The results showed that the groundwater quality in the study area was more in rank П. The basic hydrochemical types of shallow groundwater were HCO3-Ca·Mg and HCO3·SO4-Ca·Mg. The influencing factors of the hydrochemical component of groundwater were identified in the Gaoqiao diluvial fan. The quality of groundwater changed slightly from the top to the edge of the fan due to the water–rock interaction except for in Yucun and Hucun influenced by human activities. The assessment result can provide a scientific basis for the pollution prevention and changing process control of the groundwater in the hydrogeological unit of the Gaoqiao diluvial fan.

The unreasonable development and utilization of groundwater in Dehui City, China, has resulted in poor groundwater quality conditions. Based on the collection of a large amount of groundwater chemical data and hydrogeological data collected by Dehui City from 1992 to 2015, this paper uses hydrogeological analysis, graphic and other methods and ArcGIS toolbox to analyze the groundwater quality of this City. The study shows that the concentration of groundwater chemical components in the vicinity of the Songhua River is decreasing with time, and the concentration of groundwater chemical components in other regions is increasing with time. The increase of chemical concentrations are affected by human activities and water-rock interaction. The decrease of groundwater chemical concentration in Songhua River area is caused by the mixing between dilute river water and groundwater.

This study focused on quality of shallow groundwater collected around Laemchabang sanitary landfill Chonburi Province, Thailand. The sixteen public shallow wells were collected and analyzed for pH, cations (Ca2+, Mg2+, Na+ and K+), anions (HCO-3, Cl- and SO4 2-) and metals (As, Fe, Mn, Zn and Al). The results were reported by statistical and correlation techniques. It was found that, in some wells, metals such as Fe and Mn exceeded the acceptable limits. Thus, shallow groundwater around Laemchabang Sanitary Landfill would not be suitable for drinking. According to correlation analysis, pH value is positively correlated with HCO-3, Fe and Al. Ca2+ and Mg2+ are positively correlated with HCO-3 and Cl-. Arsenic is positively correlated with Fe and Mn. Most shallow groundwater samples in this area are the mixed type, Ca (Mg)Cl (SO4) type, which may occur from water-rock interaction and leakage from landfill to groundwater system.

Groundwater quality is affected by agricultural irrigation easily. Northern suburb of Yinchuan is a part of Yellow River irrigation area. Shallow buried depth of groundwater and sandy aeration bring about high vulnerability which is adverse to prevent pollution. As source of drinking water, the quality of groundwater needs to be assessed eagerly. The analysis indicated primary pollution comes from agriculture activities. Pollution loss ratio was adopted to determine the level of pollution. The results show that pollution caused by high salinity is more prominent than nitrogen pollution. The pollution is considerable and a few pieces of advice were proposed in order to improve groundwater quality.

Abstract In order to quantify the hydrochemical characteristics of groundwater in Hailun, analyze the hydrochemical process, and evaluate its health risks associated with nitrate intake, 77 shallow groundwater samples were collected and analyzed. The results show that groundwater in the study area is weakly acidic and groundwater chemical type was dominated by HCO3-Ca, HCO3•Cl-Ca, HCO3-Ca•Na and HCO3•Cl-Ca•Na. Rock weathering and dissolution, ion exchange, and human activities are the main reasons affecting the chemical composition of shallow groundwater in Hailun. The weathering and dissolution process of silicate under weakly alkaline conditions is the source of Na. The dissolution of calcite, dolomite, and gypsum are the main form of water–rock interaction. Results of health risk assessment show that the HQ value for adult males, adult females, children, and infants were in range of 0–1.52, 0–1.75, 0–3.58 and 0–6.08, respectively, and with a mean value of 0.19, 0.22, 0.44, 0.75, respectively. The harm of NO3 pollution is in the order of infant > child > adult female > adult male. The results of this study made local governments pay attention to drinking water safety issues for local residents.
