The Potability of Groundwater in Terms of Water Quality Index (WQI) of Jaipur City

摘要

This manuscript presents a comparative study of physico-chemical properties and suitability of groundwater for potability in terms of Water Quality Index (WQI). Groundwater samples from various hand pumps of eight adjacent localities of various industrial areas in Jaipur city were analyzed during monsoon session (Nov.,2002 to Jan., 2003) with the help of standard methods of APHA. The values obtained were compared with standards of ISI, ICMR and WHO. From the observations, it may be inferred that the pH, EC, Ca2+, Na+, K+, Mg2+, SO42, CO32 HCO3-, Cl", DO and BOD values are within permissible limits of ISI, ICMR and WHO but NO,-, TDS, TH, COD and WQI values show poor water quality in most of the studied groundwater samples taken from vicinal locations of various industrial sites.
