Hydrogeochemical research and water quality evaluation are an important part of groundwater development and management projects in Dehui City, Jilin Province, China. We collected 217 groundwater samples in the study area and used two multivariate statistical methods, hierarchical cluster analysis and principal component analysis to classify groundwater; combined graphical method, piper diagram, and Gibbs diagram to characterize groundwater chemical types and distinguish the water chemical control mechanism; and fuzzy comprehensive evaluation method to evaluate groundwater quality. Three major categories have been identified. Most of the groundwater in the study area is Ca-HCO3 type water. The water chemistry control mechanism is determined to be based on water-rock interaction and less evaporation. From east to west in the study area, the total dissolved solids (TDS) gradually increased, and water quality gradually deteriorated. In the whole region, 79.26% of the groundwater is suitable for drinking. With Yinma River at the boundary, the water quality in the eastern part is excellent, while that in the southwest is poor. After appropriate treatment, it can be used in industry and agriculture. The excess NO3− is mainly affected by human activities. The unique geological conditions of the Songnen Plain result in an excess amount of Fe3+ and Mn2+ in some areas. This study determined the chemical characteristics of groundwater in the study area and distinguished water quality levels. The results will be helpful for the development and management of groundwater resources.

“…Nitrogen contaminants, such as nitrate, nitrite, and ammonia nitrogen, are prevalent inorganic contaminants. Nitrate is predominantly from anthropogenic sources, including agriculture (i.e., fertilizers, manure) and domestic wastewater (Hansen et al 2017 ; He and Wu 2019 ; He et al 2019 ; Karunanidhi et al 2019 ; Li et al 2019a ; Serio et al 2018 ; Zhang et al 2018 ). Groundwater nitrate contamination has been widely reported from regions all over the world.…”

“…Various techniques that are commonly used to assess the groundwater quality are Water Quality Index (WQI), Piper diagram, Gibbs plot for drinking purpose and Sodium Absorption Ratio (SAR), Wilcox diagram, US Salinity Laboratory (USSL) diagram, kelly ratio, permeability index, percentage sodium, magnesium hazards for irrigation purpose (Chitsazan et al, 2019, He et al, 2019, Adimalla et al, 2019b. In addition to the above, multivariate statistical techniques such as principal component analysis and hierarchical cluster analysis methods are also used to evaluate the water quality by categorizing the similarity of chemical compounds and degree of contamination in water (Rotiroti et al, 2019, Merz et al, 2019, Masoud et al, 2018, Ferchichi et al, 2018, Ibrahim et al, 2019, Shankar et al,2011d The significant objective of the current study is to measure the chemical characteristics of groundwater in Yercadu Taluk, Salem, India to predict its suitability for drinking and agricultural purposes.…”

The main objective of this study was to evaluate the groundwater quality for domestic, agriculture use and to describe fluoride contamination in groundwater and their impacts on human health. 67 groundwater samples were collected and analyzed for major ions. Water Quality Index (WQI), Piper diagram and Gibbs diagrams were calculated to measure the suitability of groundwater for drinking purpose. The hazards index value was calculated to estimate the noncarcinogenic risk to adult (male, female) and children suggested by the United States Environmental Protection Agency (USEPA). The irrigation indices were calculated to evaluate the quality of water for irrigation purpose. Statistical methods such as principal component and hierarchical cluster analysis were used to analyses the interrelationship of data. Hydrochemistry of the samples shows, the major ions in the order of Ca 2+ >Mg 2+ >Na + and Cl->SO4in the study area. WQI value of groundwater, 74.62% of sample locations are good and 25.38 % of sample locations need primary treatment for drinking purpose. The results of the hazards index show that 65.67% of the sample locations exceeds the tolerable limit for non-carcinogenic risk (greater than one) for children higher than the risk level for Male and female. Statistical report of PCA and HCA reveals that Ca-Na-HCO3-F has positive loading and TDS-EC has negative loading. The study results show that rock-water interaction and anthropogenic activities are the major factors that influence the quality of groundwater. The continuous intake of excess concentration fluoride causes bone diseases and teeth problems.
