Geospatial Variability and Drinking Water Safety Scenario of Groundwater in Aland Taluka, Kalaburagi, Karnataka

Abstract

Groundwater quality and distribution systems are major concerns in hydrogeology which needs proper
understanding in order to relate the quality and quantity of groundwater. Water quality represents the chemical
constituents or ionic concentration of water. Drinking water is very sensitive and needs immediate prevention of
pollutants to groundwater reserves. In this sense, Water Quality Index (WQI) is one of the essential factors to determine
the quality and grade of the groundwater. Groundwater is highly influenced by lithological assemblage prevailing in the
area. The study area is covered by Deccan traps which consist of basalts. The variation of water quality from both open
wells and bore wells in accordance to the depth variations were analyzed with reference to water table. The significance
of the research illustrated the society related problems from water quality using geospatial and decision making tools,
and quality of the water using WQI analysis.
