Abstract :  Access to safe drinking water is fundamental to public health and sustainable development. This study assessed the spatial variability of drinking water quality across four hoblis including Elavala, Jayapura, Kasaba, and Varuna within Mysore Taluk, Karnataka, India. Sixteen physicochemical and microbiological parameters (including pH, total dissolved solids, electrical conductivity, calcium, magnesium, nitrate, fluoride, Escherichia coli, and total coliforms) were analyzed between 2023 and 2025 using data from the Jal Jeevan Mission (JJM) monitoring program and supplementary field sampling. Each parameter was evaluated against Bureau of Indian Standards (IS 10500:2012) limits and classified as Safe, Permissible, or Unsafe. Spatial distribution maps were generated using GIS-based choropleth analysis, and inter-hobli differences were examined through one-way ANOVA. Results indicated that over 80% of villages met safe thresholds for most parameters, though moderate exceedances were recorded for total hardness, alkalinity, and conductivity. Microbiological contamination was minimal, confirming effective source protection and sanitation management. Jayapura hobli exhibited slightly higher total dissolved solids and nitrate concentrations, likely reflecting agricultural influence. The overall water quality index indicated good to moderate conditions across the taluk, with no villages categorized as unsafe. These findings show the importance of spatially explicit monitoring to inform region-specific water management and demonstrate the value of integrating GIS with statistical analysis for sustainable rural water governance.
