Hydrogeological Study and Groundwater Quality Analysis Along Hoovinal Halla Basin, Belagavi District

Water is precious source which is available in highly irregular fashion. Due to rapid urbanization, the exposed soil surface gets diminished and ground-water recharge gets drastically reduced and therefore natural ground water recharge gets affected. The objective of this paper was to investigate the ground water contamination and to analyze its impact on the human life. The area is mostly covered with weathered rocks except certain patches. It is seen that less weathered rocks are capable of releasing good quality of major cat ions such as Na, K, Ca, Mg and SiO2 and sulphates on weathering. The weathering is very slow at pH 7 to 8, resulting in change in chemical composition of groundwater in crystalline rock area. When the water samples were subjected to the parameter analysis it was found that the Hardness, BOD, DO, Carbonate were high in quantity, which is not suitable for domestic activity. In this study area human inhabitation is mainly depended on bore well water for drinking and agriculture purpose, due to this the groundwater conservation is severely affected and due to this water crisis problems are experienced during summer.
