Present study deals with the assessment of physico-chemical parameters of groundwater samples of jajmau area of Kanpur city. Statistical analysis has also been carried out with the help of correlation coefficient (r) between parameters of summer and monsoon to evaluate their significance. The observed values of various physico-chemical parameters of groundwater samples were compared with water quality standards. Out of 78 correlation coefficient, the value of r between total hardness and total alkalinity was found to be 0.77; correlation of TDS with conductivity (1.0) was found to be highly significant (0.7<r<1). Correlation values lie between 0.31-0.5 where 32 parameters were found to be negatively correlated while rest 46 are positively correlated. Total hardness, conductivity, pH, total alkalinity values were found to be higher when compared with water quality standards. Appreciable significant positive correlation holds for turbidity, total hardness, phosphate and chromium whereas negative correlation was observed for NO3, SO4, F and Cr.
