It is estimated the concentrations of fluoride in groundwaters used for constumption purpose. Samples from different mineral water suppliers (bore well sources) and municipal and/or panchayat drinking water taps were collected and analyzed for fluoride using spectrophotometer. The caliculation of fluoride concentrations against absorption (optical density at 542nm) in consumption waters collected are suitable for human or not, were determined by the standard curve of ammonium fluoride solution ranged from 1 to 10 mM. In addition, the leached fluoride estimation from water was perfomed in small 15 liters plastic buckets using phosphate solubilizing bacteria (PSB). The PSB was rooted in plastic buckets mixing with calcium (white cement) which was painted with a brush on inner surface of the bucket
