“…Such contamination can be statistically interpreted and it is very useful due to its relative importance in evaluating the combination of large chemical variable dataset. In the last decades, methods such as hierarchical cluster analysis (HCA), discriminant analysis (DA), correlation analysis, and principal component analysis (PCA) have become accepted in identifying variations and sources of groundwater pollution (Zhang et al 2012;Gordana et al 2014). Principal component analysis (PCA) and Spearman's correlation matrix have been frequently applied to analyze the pollution parameters in groundwater (Selvakumar et al 2014).…”

A total of 20 groundwater samples were collected from both dug and bore wells of southern Tiruchirappalli district and analyzed for various hydrogeochemical parameters. The analyzed physicochemical parameters such as pH, electrical conductivity, total dissolved solids, calcium, magnesium, sodium, potassium, bicarbonate, carbonate, sulfate, chloride, nitrate, and fluoride are used to characterize the groundwater quality and its suitability for drinking and irrigational uses. The results of the chemical analysis indicates that the groundwater in the study area is slightly alkaline and mainly contains Na ? , Ca 2? , and Mg 2? cations as well as HCO 3 2-, Cl -, SO 4 2-and NO 3 -anions. The total dissolved solids mainly depend on the concentration of major ions such as Ca, Mg, Na, K, HCO 3 , Cl, and SO 4 . Based on TDS, 55 % of the samples are suitable for drinking and rest of the samples are unsuitable for drinking. The total hardness indicates that majority of the groundwater samples are found within the permissible limit of WHO. The dominant hydrochemical facies for groundwater are Ca-Mg-Cl, Ca-HCO 3 , and Ca-Cl type. The USSL graphical geochemical representation of groundwater quality suggests that majority of the water samples belongs to high medium salinity with low alkali hazards. The Gibb's plot indicates that the groundwater chemistry of the study area is mainly controlled by evaporation and rock-water interaction. Spearman's correlation and factor analysis were used to distinguish the statistical relation between different ions and contamination source in the study area.

Ulaanbaatar (UB), the capital of Mongolia, is one of the fastest-growing cities in the developing world. Due to increasing demand driven by rapid population and industrial growth, sustainable water resource management is required. Therefore, we investigated sustainability in UB from the perspective of water quality. During five sampling campaigns, we collected 135 water samples (58 from bedrock wells, 44 from shallow wells tapped into the alluvial aquifer, 24 from rivers, and 9 from springs). The hydrochemistry of the water samples was controlled by two major processes: NO 3 contamination, and silicate and carbonate mineral weathering. The groundwater samples could be classified into three groups based on their NO 3 levels and spatial distribution. Group 1 had natural background NO 3 levels (median: 1.7 mg/L) and silicate weathering-dominant water-rock interactions and was distributed in the alluvial aquifer along the floodplain. Group 2 was dominated by carbonate weathering processes, had a maximum NO 3 concentration of 47.4 mg/L, and was distributed between the riverbank and upslope area; overall, it reflected ongoing contamination. Group 3 was distributed in the upslope Ger districts and showed significant NO 3 contamination (range: 64.0-305.4 mg/L) due to dense and poor living conditions. The stable isotope signatures indicated that the city's major water supply from riverbank filtration (i.e., Group 1 wells) mixed dynamically with the river; therefore, it showed no sign of NO 3 contamination. However, the isotope values and bedrock groundwater quality of wells in Groups 2 and 3 implied that they were closely connected, with the same water source, and showed a strong potential for expanding NO 3 contamination toward Group 1 wells. To support sustainable development in UB, the implementation of appropriate institutional measures to protect and preserve water resources, with systematic spatio-temporal monitoring and a focus on Ger districts, is crucial.

Water samples classified to the class with the maximize membership [22] .. [63] is the largest and F-is the least in surface water. The coefficient variation of turbidity is the largest in surface water, it could be effluents from agricultural return flow [27] ; it did not meet the World Health Organization(WHO1996) guideline for drinking water, which is set at 5 NTU [63] .…”

Water quality assessment in pastoral of Tibetan Plateau, which is water sources for about 40% of world's population and the runoff-yield area of Yellow rivers, is very important. In this paper, Xiahe county which belongs to Tibetan Plateau pastoral was investigated. Six parameters(via, chloride, COD, ammonia nitrogen, nitrate, fluoride, sulfate) were selected to assess the water quality and health degree by using fuzzy comprehensive evaluation methods. The hydrochemical type in surface water was of HCO3 --Mg 2+ -C a2+ type. The cations and anions in surface water were mainly from weathering and dissolution of carbonate rock. Results showed that the water quality in all 69 sampling sites was all of class Ⅰ. The integrated health degree reached more than 0.85 and the health rate were 100%. Although ammonia nitrogen was regarded as the main contamination factor, but it had a little effect on the entire body of water. Overall, the surface water qualities of most samples in Xiahe County was good condition.
