Abstract
Water is essential natural resource for sustaining life and environment which
we have always thought to be available in abundance and free gift of nature. However,
chemical composition of surface or sub surface, is one of the prime factors on which the
suitability of the water for domestic, industrial or agriculture purpose depends. Fluoride is a
chemical element that has shown beneficial effects on teeth at low concentrations, it can also
be quite detrimental at higher concentrations. High concentrations of fluoride (up to 6.2
mg/L) are recognized features of the study area. The basement rocks like granitic gneiss,
schist, shale and sandstone provide abundant source of fluoride in the form of silicates,
biotite, hornblende and glaucaphase. A correlation study of water quality parameters with
Fluoride content is performed on groundwater samples from Gadag and Bagalkot district.
The study suggests that the water samples with higher F − concentration generally have
relatively higher pH value, implying that alkaline environment favours the replacement
exchangeable F − in fluoride rich minerals by OH − in groundwater. The positive correlation of
TDS implying that dissolved solids gives more opportunity for fluoride to be present and
most of the metal fluoride are soluble. Since nitrate is an oxidizing agent it increases the
solubility of fluoride in groundwater. Hardness of water is mainly due to calcium salts in
water. As the hardness increases, formation of calcium fluoride (CaF 2 ) which is an insoluble
salt increases.. Thus the origin of the fluoride is mostly from weathered gneiss, schist shale
and sand stone. In this study arcGIS approach to develop maps based on the groundwater
quality has been found to be very useful. GIS data base also helps in decision making process
by identifying the most sensitive zones that need immediate attention.
