| Abstract/Description: | A large portion of the drinking water requirements of Tezpur municipal area of Assam (India) is supplied by ground water wells. The quality of this ground water was determined by taking samples from 27 wells within a study area of 22.5 km2. The purposes of this investigation were to provide an overview of current ground water quality and to determine spatial distribution of quality parameters in the study area using GIS tools. The thematic maps of each parameter were generated using geostatistical (Kriging) approach. Experimental values were tested for Kriging models to identify the best fitted for the eight water quality parameters (calcium, iron, nitrate, chloride, pH, TDS, total hardness and alkalinity). Concentrations of ground water quality parameters were compared with World Health Organization (WHO) and Indian Bureau of Standard (BIS) drinking water guidelines. The thematic maps of eight ground water quality parameters were used for ground water quality index (GWQI) map generation using overlay & index method. Corrosive nature of ground water was examined by using Langelier Saturation Index (LSI) model and Baylis curve procedures. The water quality indices reveal the suitability of ground water quality for drinking purposes. |
