Abstract: WQI i. e. water quality index has been calculated on the basis of methods suggested by Tiwari & Mishra (TM) and Canadian Council of Ministers of Environment (CCME) The calculations are based on the studies of parameters for underground water of seven sights of Bullowal in Hoshiarpur Distt. (Pb. ). A comparison of values thus found on TM and CCME methods has been made. Efforts have been also made to arrive at a better option of the two for WQI calculations. Fairly close agreement of values of WQI calculated on CCME method among different agencies i. e. WHO, EPA, CAN, EU, BIS, ICMR and AUS is seen, whereas variation of values for the TM method is wider.
