Cluster and Factor analysis were performed on 55 well representative groundwater samples taken from Water Authority open files and samples during 2011. A total of 12 water variables data including, Na, Ca, K, Mg, CI, HCO3, SO4 and NO3 beside to chemical analysis like TC, TDS and PH were analyzed. The study finds that there are 2 factor model variation : factor one include concentration of Na , k, Mg ,Cl , EC, TDS ,NO3 ,HCO3, Ca and SO4 ,where as factor 2 includes TC and PH . These 2 factor explains 79.8% of the total groundwater quality variation. A two main hydrochemical groups were demonstrated using Q- mode cluster analysis , the first group shows the similarity between, K, Mg, NO3 and Na ,which probably represent the effects of weathering of the rich feldspare and mica , in addition to agriculture fertilizers. The second cluster is Cl and HCO3 dominated but also contains low concentration of SO4.

Hydrochemical Types

Purpose The chemical analysis of wells in the Ardabil area, Ardabil Province NW of Iran, was evaluated to determine the hydrogeochemical processes and ion concentration background in the region. The purpose of this study is to analyze the hydrochemical quality of groundwater in Ardabil aquifer in order to assess the suitability of the waters for different uses. Design/methodology/approach The chemical analysis of 75 water wells in the Ardabil area, was evaluated. Over the entire area, the dominated hydrochemical types are: Na-Cl, Na-HCO3-Cl-Mg, Ca-SO4, Ca-Mg-SO4-Cl and Ca-Mg-HCO3. The abundance of the major ions is as follows: Na+>Ca2+>Mg2+>K+ and SO42–> Cl–>HCO3– and major ion concentrations are below the acceptable level for drinking water. Most of groundwater samples fell in the soft water category. All of groundwaters belong to the excellent category and can be used safely for irrigation.

Drinking Purpose

Water is important for living organisms on the Earth. Present development activities have put pressure on water resources. Groundwater is under more stress because of high exploitation for drinking, irrigation and industrial purposes. In the arid to semi-arid climatic zones groundwater is very important for sustaining day to day activities and agriculture and industrial purposes. The present study area Charkhi Dadri block in Charkhi Dadri district, Haryana was selected to 0 0 study groundwater quality for drinking purpose. The geo-coordinates of the study area are latitudes 28.49 N to 28.70 N 0 0 and longitudes 76.05 E to 76.47 E and covers an area of 396.57 sq. km. In the study area ten groundwater samples were collected in double capped 250 ml plastic bottles. Geo-coordinates of the sample locations were noted using mobile GPS. Chemical analysis of all the ten groundwater samples were done using Tamilnadu Water Supply and Drainage Board (TWAD), Chennai prepared Field Water Testing kit for twelve chemical parameters viz. pH, alkalinity, hardness, chloride, total dissolved solids (TDS), fluoride, iron, nitrite, nitrate, ammonia, phosphate and residual chlorine. Chemical analysis results were entered in excel software and prepared bar graphs. Result of groundwater samples analysis were compared with BIS (IS 10500:2012) drinking water standard to know the suitability of groundwater for drinking purpose. The study shows that pH ranges 7 to 8, alkalinity 200 mg/l to 450 mg/l, hardness 130 mg/l to 800 mg/l, chloride 40 mg/l to 1200 mg/l, TDS 552 mg/l to 2820 mg/l, fluoride 0.5 mg/l to 5 mg/l, iron nil to 0.3 mg/l, ammonia nil to 1 mg/l, nitrite 0.2 mg/l to 1 mg/l, nitrate 45 mg/l to 100 mg/l, phosphate nil in all the ten groundwater samples and residual chlorine nil to 0.2 mg/l. The study is highly useful for planning and monitoring of groundwater for drinking purpose in the study area.

Groundwater is the very vital natural resource which must not be essentially utilized and sustained unless its quality is precisely evaluated. A total of 41 groundwater samples were collected from selected areas within Basrah province in 2014 to assess its suitability for irrigation uses. Physicochemical indices such as permeability index (PI  5.44 to 84.32 meq L-1), percentage of sodium (Na%  8.87 to 51.03 meq L-1) and sodium adsorption ratio (SAR 0.11 to 39.33 meq L-1) indicate that the groundwater in the study area is suitable for irrigation except for few locations.  The results show that the high values of total dissolved solids (TDS > 3000 mg L-1) for some samples minimized their application for irrigation. Principal component and cluster analyses were usually used as a supporting tool for assistance arrange and interpret the chemical analysis. Three principal components explanation for most of the variability in the groundwater data were represented.

The main goal of this research is assessment the groundwater resources for irrigation purposes at the western portion of the River Nile –Minia district- Egypt. The research depend on representation and calculation the resulted of chemical analysis of 96 groundwater samples collected from 96 pumping well During autumns 2011 from quaternary aquifer. the resulted reviled that; 25% of groundwater samples within the range of none restriction on use and the rest are margin according TDS content, most of samples are good for irrigation in all soils as they located in classes (C2-S1) and (C3-S1) and suitable for irrigation all crops as belong to SAR values and RSC hazard. But it restricted by boron ion concentration.
