Abstract

Ground Water quality plays a key role in groundwater management and quality protection; hence it is very much essential to appraise the groundwater quality not only for its current needs but also a probable source of water for upcoming consumption. The study area selected was ground water of Honnali Taluk, Davangere district, Karnataka, India. In our study, first we mark the sampling locations in twenty five different zones of the city, then locations were established and groundwater samples were collected. In the present work an attempt has been made to identify the ground water quality of the region in Pre monsoon, monsoon and Post monsoon phase in year 2020. The physico-chemical variables like pH, electrical conductivity, total hardness, total alkalinity, chloride, fluoride, sulphate, sodium, potassium, calcium, magnesium and nitrate were chosen to analyze the potable ground water quality of the city. Better water quality was found in Pre-monsoon season than Post-monsoon season. Extent of pollution happened due to over utilization of ground water, urbanization and anthropogenic activities. TDS shows highly positive correlation with EC in pre monsoon and post monsoon indicating. In some of the area, nitrate concentration increases in post monsoon.
