The present study seeks to evaluate the hydrogeochemistry of Tabriz plain in NW Iran, through major ion chemistry and their spatial variations. In order to accomplish these, groundwater sampling from 30 shallow and deep wells in the plain were carried out in July 2012. The water samples were analyzed for various physicochemical parameters such as pH, EC, Na ? , Ca 2? , K ? , Mg 2? , Cl -, CO 3 2-, HCO 3 -, SO 4 2-and NO 3 -. Chadha's diagram demonstrates that most of the groundwaters belonged to the Na-Cl and mixed Ca-Mg-Cl hydrochemical facies. The concentrations of some major ions in groundwater are above the permissible limit for drinking and domestic purposes except for a few locations. The results of saturation index computation show that dissolution of gypsum, anhydrite, halite and silicate minerals occurs frequently across the study area, whereas the groundwater is supersaturated with regard to calcite and dolomite. Cross-plots show that weathering and dissolution of different rocks and minerals, ion exchange, reverse ion exchange and anthropogenic activities, especially agricultural activities, are effective in hydrogeochemistry of the study area.

“…It explains that Pb and Zn was derived into groundwater by non-point sources like agricultural fertilizers (Zn based) leaching process, usage of carbon waste to irrigation land from industries, toxic pesticides and fungicides and point sources from industries which located on the belt of the river basin. There are several textile industries located in and around Karur district; the government implemented the zero discharge effluents into river, big factories had even dug tube wells to a depth of HCA was done to classify the parameters into groups based on their similarity with each other, whereas the Q-mode was performed to classify the parameters into groups based on their dissimilarity with each other (Nagaraju, Sunil Kumar, Thejaswi, & Sharifi, 2014;Davis, 2002). R-mode CA was performed on the surface water samples constitute of three clusters, where as elements belong to same group was instigating from the same sources.…”

Several textile and bleaching industries in the city of Karur, discharge their effluent and was mixed with municipal sewage let into the river Amaravathi at different discharge points. Concentration of trace elements (Cd, Pb, and Ni) exceeded their permissible limits (.003, .01, and .02 ppm, respectively) prescribed by the World Health Organization. C d (Degree of contamination) and HEI (Heavy metal evaluation index) values were calculated, C d value of 50% samples have <4 indicates low degree of contamination and for groundwater samples only one-third samples were observed in low pollution and the remaining samples fall in medium to high degree of pollution. HEI value indicates that the average value (12.510, 12.514, and 12.164) of both the samples were above the low pollution range. Good positive correlations observed for Mn, Ni, and Fe with r value from .522 to .913. Principal component analysis (PCA) was used to analyze the data and to identify possible sources of these heavy metals. Three factors for surface water and two factors for groundwater were extracted, where the first three factors account for approximately 58.7% of the total variance of the data-set. The results of groundwater samples show that the factor 1 and 2 accounted for 74.508 and 71.261% of the total variance. The data thus obtained are a sign of anthropogenic and mineral source for these elements in river and groundwater. The spatial distribution map based on ordinary kriging showed that elevated concentrations of heavy metals were located in the upper and down streams of the Amaravathi River basin. The dominance of heavy metals in groundwater and surface water of the Amaravathi river followed the sequence as

“…PCA is an efficient tool to discriminate patterns in groundwater chemistry from huge physical and chemical analytical data (Kiymaz and Karadavut 2014;Nagaraju et al 2014;Okiongbo and Douglas 2015). Factor analysis is one of the significant multivariate techniques that perform through PCA method.…”

Thirty-nine (23 dug and 16 tube well) samples were geochemically evaluated and investigated to ascertain the quality of water in Khipro, Sindh. The analytical results exhibited abundance of major cations and anions in Na ? [ Ca 2? [ Mg 2? [ K ? and Cl-[ HCO 3-[ SO 4 2sequence. Stiff diagram showed dug well sample have high Na-Cl and moderate Mg-SO 4 content as compared to tube well samples. Majority of dug well samples appeared as Na-Cl type on Piper diagram while tube well samples are mixed type. Gibbs diagram reflected evaporation as a dominant phenomenon in dug well; however, tube well samples are declined toward rock dominance. Process of ion exchange was witnessed from Na ? versus Cland Ca 2? ? Mg 2? versus HCO 3-? SO 4 2plots. Principal component analysis also discriminates dug well and tube well water by means of positive and negative loading based on physical and chemical composition of the groundwater. Studied and computed parameters like pH, EC, TDS, TH, Na ? , K ? , Ca 2? , Mg 2? , Cl-, SO 4 2-, HCO 3-, sodium adsorption ratio, magnesium adsorption ratio, potential salinity, residual sodium carbonate, Na%, Kelly's ratio, and permeability index were compared with WHO to evaluate studied water for drinking and agricultural purposes. Except Na ? and K ? , all chemical constrains are within the allowed limits, set by WHO for drinking water. Similarly, most of the groundwater is moderately suitable for irrigation uses, with few exceptions.
