Water chemistry and control of weathering of Pichola Lake, Udaipur District, Rajasthan, India

  • B. K. Das

The water chemistry of Pichola lake revealed that it is dominated by Na and HCO3. The lake water chemistry strongly reflects the dominance of continental weathering aided by anthropogenic activity, such as tourist influx, developmental activities in the catchment area, and disposal of untreated municipal and domestic sewage into the lake basin. The supply of major ions is mainly through weathering of the silicate rock exposed in the drainage basin and the contribution from saline and alkaline soils/groundwater because of the semiarid conditions of the region. The increase in phosphate loading and consequent depletion of silica suggests biological consumption of the latter. The observed chemical data of Pichola lake was used to predict the mineral assemblages in the carbonate and aluminosilicate system. It demonstrates that calcite and dolomite are the possible minerals that are in equilibrium with the lake water system and that the lake water chemistry is in the range of stability of kaolinite.
