GROUNDWATER QUALITY AROUND MYSORE, KARNATAKA, INDIA
Abstract:Ground water samples were collected in the vicinity of Mysore, Karnataka, India, and were analyzed for inorganic constituents. These analyses were carried out to study changes in ground water quality that may reflect rock-water interactions as the water passes from recharge to discharge zones. Four hydrologic flow regimes were identified in the study area and variations in their ground water chemistry determined. Ground water in this area was classified as either CaHCO3 or MgHCO3 type. The anions and cations in these samples showed saturation characteristics of CaCO3. The hydrochemical data were modelled using WATEQ4F. The ground waters were oversaturated with respect to calcite and to a lesser extent with dolomite. Sixty percent of the ground water samples had nitrate concentration higher than the World Health Organization (WHO) limit of 45 mgL−1, whereas, eighty six percent of the samples had fluoride concentration less than 1.0 mgL−1. The concentration of all the trace metals except iron and zinc was close to the detection limit at most of the sampling sites.
