Five water samples were collected from tap and hand pump of various area of tonk city. The physical chemical parameters such as fluoride, iron, calcium, magnesium, sulphate and nitrate were analyzed in the water samples, to characterize the ground water quality and suitability for drinking purpose. All the water samples were compared with Indian standard of drinking water prescribed by bureau of Indian standard BIS 10500:2012. The physical chemical analysis of water samples of Tonk city showed that Fluoride varied from 0.0 to 0.3 mg/l, Iron from 0.1 to 22.22 mg/l, Calcium from 45.29 to 252.50 mg/l, magnesium from 6.65 to 37.84 mg/l, Sulphate from 25.74 to 94.65 mg/l and Nitrate from 2.25 to 22.00 mg/l. The result of physical chemical analysis of water samples of Tonk city indicated that tap water of Jawahar Bazar Area (S1), Taj colony Area (S2) and hand pump of Mehandi Bagh Area (S4) were suitable for drinking purpose but hand pump water of Takhata Area (S3) and Civil line Area (S5) were unsuitable for drinking purpose on the basis of calcium and iron concentration. This study thus concludes that hand pump water in study area is chemically unsuitable for drinking and it is recommended to carry out a proper water quality program in study area.
