The paper presents the groundwater chemistry of the samples in some detail. This includes ion concentrations, fluoride etc. Despite the fluoride contamination prevalent in the area, none of the samples had fluoride concentrations above the permissible limits. Data analysis indicates a strong correlation between these low fluoride levels and the higher concentrations of calcium and bicarbonate in the area.
Leachate from pit toilets in Mulbagal town increases the concentration of sodium, potassium, calcium, bicarbonate nad nitrate ions in the groundwater, which affects the ability of fluorite to dissolve, and so prevents the rise of concentration of fluoride in the groundwater.
