“…The current study employed the multivariate statistical approach to accomplish its main objective. In recent times, several studies have employed these methodologies to evaluate the hydrogeochemical characteristics of groundwater quality [ [ 19 , [77] , [78] , [79] , [80] ]]. Descriptive statistics were used to summarize the groundwater data, including mean, median, minimum, and maximum values for the water quality indicators under study.…”

“…All statistical analysis were performed using RStudio 2022.02.0 b y implementing R programming language. However, the analysis of hydro-geochemical data frequently entails the consideration of multiple water quality indicators and therefore, it regarded as a multivariate problem that requires multivariate statistical analysis for identifying the origin of source for mineralization [ [ 79 , 80 , 85 ]]. In this regard, this study utilized the principal component analysis (PCA) and cluster analysis (CA) for identifying the sources of origin of the hydrogeochemical.…”

“…In the research of groundwater chemical process, the ion equivalent relationship between [(Ca 2+ +Mg 2+ )-(SO 4 2− +HCO 3 − )] and [(Na + +K + )-Cl − ] is frequently utilized to explore the impact of the water-rock interaction on groundwater chemical composition during the exchange reaction and dissolution [32]. The possibility of chemical reactions can be predicted through the calculation and analysis of the chemical equilibrium states between minerals and water for water-rock interactions [33]. Ca 2+ increased significantly with the increase in TDS in the Hancheng mining area, indicating that gypsum dissolution occurred in the Hancheng mining area because gypsum dissolution was not related to the carbon dioxide content, but only related to water and time [34].…”

A total of 18 samples of shallow groundwater around the Hancheng mining area in the Guanzhong Basin were collected from 1–4 May 2018. According to the analysis of hydrochemical data, the Gibbs semi-logarithmic diagram and Piper diagram were used to research the hydrogeochemical behavior of shallow groundwater around the Hancheng mining area in the Guanzhong Basin. The results of the groundwater hydrochemical analyses shown on the Gibbs and Piper plots are as follows: The chemical composition analysis showed that the main cation components were Mg2+, Ca2+, Na+, and K+, the anion components were HCO3−, Cl−, and SO42−. A measure of 89% of the groundwater samples in this area were freshwater, the HCO3− were mainly dolomite, calcite, and gypsum dissolved precipitation resulted. Na+ and Cl− came from the dissolution of halite. Most of the groundwater was of the SO4·Cl-Ca·Mg type, accounting for 61.1%. The main ion chemistry of the shallow groundwater in this area is controlled by rock weathering, and pyrite oxidation is a significant factor affecting the SO42− concentration. These research results will help analyze the formation mechanism of chemical components and provide some basic data for the evolution of mine water in this area in the future.

This study aimed to characterize the chemical composition and spatial distribution of groundwater in the Kızılırmak Delta of Turkey and to evaluate the suitability of groundwater in the Kızılırmak Delta for drinking water use through a Water Quality Index (WQI) assessment. Eleven water parameters, including nitrate (NO3−), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), chloride (Cl−), potassium (K+), bicarbonate (HCO3−), sulfate (SO42−), hardness (measured as CaCO3), electrical conductivity (EC), and pH were analyzed to determine the water quality of each groundwater sample. The WQI was determined using the weighted arithmetic index method and the method specified by the Canadian Council of Ministers of the Environment (CCME). The spatial distribution of the result for all observation wells was plotted. Principal Component Analysis (PCA) was generated utilizing the analytical data from eleven selected samples. As a result of the study, according to the calculated WQI values, the water in most of the wells was not suitable for drinking purposes. The minimum Ca2+ concentration in the study area was 108,817 mg/L, and the maximum was 692,382 mg/L, which showed that the samples in all wells exceeded the WHO limit. The same situation is valid for Mg2+, and the values vary between 100.383 and 5183.026 mg/L. From the spatial distribution of the water quality parameters it has been understood that the eastern part of the region is more suitable than the western part for drinking purposes. The results from correlation analysis showed the strongest positive correlation between Mg2+ and Na+ and Na+ and EC as 0.989. The present study shows that the groundwater of the delta, which has deteriorating water quality, should be treated before it is used for drinking water and protected from contamination hazards.
