Statistical analysis and physicochemical characteristics of groundwater ?quality parameters: a case study

The assessment of groundwater quality was carried out by taking the shallow wells samples near bank River Indus at downstream Kotri barrage; study area covers arid region Hyderabad, Sindh. space occupied about 1-2 km used for quantification geochemical characteristics aquifer that lies on left side river. A total 13 were collected during pre-monsoon and post-monsoon seasons. All examined characterisation physicochemical parameters such as Total Dissolved Solids ranged from 320 mg/l to 4011 mg/l, Hardness 120 1320 Chloride 160 2260 Sulphate 61 777 pH 6.9 8.1. findings demonstrate presence high quantity a in contrast guidelines values World Health Organization (WHO) drinking water. Besides, T-value applied check variation pre- results between parameters, which found significant chloride 2.701 with p-value 0.031, fluoride 3.039 0.019 iron 2.957 0.021. Moreover, Correlation coefficients among different determined showed correlations become weaker it also becomes insignificant. An attempt has been made develop linear regression equations predict concentration water constituents. significantly positive correlation 1 5% many parameters. hardness 0.969, 0.988, sulphate 0.994 using conventional level significance (0.05). However, no apparent changes visualised onset seasons over year.
