Abstract
Groundwater is a major source of municipal and private water supply in Gulbarga city. Water samples were collected from spatially referenced bore wells located in various wards of the city. 150 bore well water samples were analyzed for electrical conductivity (EC), pH, total dissolved solids (TDS), total hardness (TH), Ca2+, Mg2+, Na+, K+, HCO3-, CO32- Clˉ, SO42-,NO3ˉ, F and Fe. All tests were performed as per standard methods and water quality was compared for both Indian and WHO drinking water standards. Significantly positive correlation at 1 and 5% was found between many parameters. EC prediction with multiple R2 value of 0.999 indicated that 99.9% variability in observed EC could be ascribed to Clˉ (76%), HCO3ˉ(12.5%), NO3- (10.3%) and SO42- (1.1%). Multiple regression models can predict EC at 5% level of significance. Nitrate, chlorides, TDS and fluoride concentration exceed permissible level of drinking water in 75, 41, 95 and 3.33% of the samples respectively. It is recommended to treat groundwater prior to domestic use. Key words: Groundwater, water quality, bore well, water supply, correlation, regression
Highlights
Groundwater is the prime source of drinking water supply for many of the Indian rural and urban habitats, like other parts of the world
Rasula and Rasula (2001) studied groundwater quality for Belgrade city, for the zones of infrastructure facilities such as roads, railway, oil and gas pipelines, which may be considered as potential linear polluters
The main objective of the study is to assess the quality of groundwater based on large number of spatially referenced sampling wells located in various wards of the city
Summary
Groundwater is the prime source of drinking water supply for many of the Indian rural and urban habitats, like other parts of the world. Contamination of groundwater results in poor drinking water quality, high clean-up costs, high costs for alternative water supplies, and/or potential health problems. Rasula and Rasula (2001) studied groundwater quality for Belgrade city, for the zones of infrastructure facilities such as roads, railway, oil and gas pipelines, which may be considered as potential linear polluters. He concluded that with traffic development and economic growth, many potential groundwater sources would not be adequately exploited if hydro geological investigations are not undertaken in zones of infrastructure
