Abstract

Hydro-Geochemical study of part of Yale Mallappa Shetty Kere (YMSK) watershed comprising two adjacent third order basins has been carried out. There are Twenty one water bodies including two major tanks viz., Singanayakanahalli kere and Gantiganahalli in the study area. Basin morphometry, geology, soil, slope, land use / land cover, transmissivity, depth to first fracture, depth to second fracture, depth to third fracture, resultant layers of Electrical Resistivity Survey which includes Resistivity of Soil, weathered zone, Bedrock, thickness of soil and weathered zone studied in detail using experimental data, Remote Sensing and GIS. Land use/ land cover both regional and around the contaminated bore wells have been studied. Nine borewell water samples collected and analysed for their physico-chemical parameters to understand the groundwater quality. Heavy metals like lead, zinc, copper, Iron, cadmium also analysed. Iron and Nitrate crosses the permissible limit in two bore wells. The details of land use / land cover around the bore wells have been used to identify the sources of contamination. The presence of big factories as well as small scale industries, agricultural practices, waste dumpsites, residential patches, vehicular traffic, vehicle garages, gasoline stations, quarries, air base, firing ranges, air traffic, asphalt manufacturing units, solar lamp manufacturing unit in and around the study area is playing a devil role in contaminating the water. Pollution Prone Zones have been delineated and validated. A comparative analysis of contaminated region and pollution prone zones has been made and it is matching with marginal exception.
