title: Hydrochemical investigations and correlation--analysis of ground water quality of Jaipur city, Rajasthan (India).
abstract: The objective was to investigate the quality of drinking water of Jaipur city during pre-monsoon session (April 2006 to June 2006). Physico-chemical parameters like pH, EC, TDS, Ca2+, Mg2+, Na+, K+, CO3(2-), HCO3(-), Cl(-), SO4(2-), NO3(-), F(-) and TH were analyzed by adopting the standard method of APHA. To assess the quality of ground water, each parameter was compared with the standard desirable limit of that parameter stipulated for drinking water as prescribed by BIS. A correlation analysis was conducted to determine the correlation coefficient (r) among the parameters. The highest correlation was found between EC and chloride (r = 0.986, p = < .0001). EC showed highly significant positive correlation with chloride, Mg++, Na+, TDS and TH while significant inverse correlations were found in four cases, i.e. between pH and bicarbonate, between carbonate and bicarbonate, between pH and TDS and between sulphate and pH, while potassium, nitrate and fluoride did not show any significant correlations with any other parameters studied.
