Abstract
Twenty water samples were collected from rural communities of Tehsil Purwa district Unnao (U.P.) and analysed for fluoride and other physico-chemical parameters like colour, odour, temperature, turbidity, suspended solids, pH, hardness and alkalinity which influence the fluoride concentration. The fluoride ion concentration in these areas ranged from 1.5 mg/L to 2.5 mg/L where as permissible limit for fluoride ion concentration is only 1.5 mg/L.
