The total area of Barna Watershed is approximately 1129 Sq. Km. The aim of the study was to analyze the observed ground water quality parameters and to create spatial map for drinking water purpose for Barna Watershed. For the above study ground water Samples were collected from the field and some GWQ data were collected from PHED, M.P and National Rural Development Water Programme (IMIS) website under Ministry of Drinking water & Sanitation. The GWQ layers were generated separately for each element for Both Pre-Monsoon and Post-Monsoon Season, from the well point layers with the help of Inverse Distance weighted Method (IDW) interpolation technique using ArcGIS 9.3 software. Each element wise layer has been categorized into three categories (1) potable water in Desirable limits (2) Potable water in permissible limits (3) Non-potable ground water, as per BIS standard 2012. Integrating layers of pre-monsoon; pre-monsoon Ground Water Quality map has been prepared and integrating layers of post-monsoon; post-monsoon Ground Water Quality map has been prepared. Integrating the pre & post monsoon Ground water quality map, final ground water quality class map has been prepared. The Final Ground Water Quality class map has been divided into 9 classes as the standard given by the NRSC, ISRO; Ground Water Quality, manual of RGNDWM-PH IV. The Final Ground Water Quality Class map of Barna Watershed shows, out of 75.04% Non-Potable area73.12% area is Non- Potable due to excess of Iron and out 65.51% Habitations which is falling in Non-Potable class, 56.89% habitation are severely affected by excess of Iron.
