In this paper, equation (1) has been used because target values for each parameters lies within the range of
permissible limit. For example, the permissible range for pH corresponding to domestic purposes varies between 6.5
(min Ct) to 8.5 (max Ct) as shown in Table 1. Table 1 summarizes the normalized values of all parameters for
sampling groundwater well located at Bana. Similarly, normalized values of all other parameters have been
calculated at all sampling wells.
