Drinking water quality with respect to fluoride, iron, and nitrate content has been carried out in Kamrup district of Assam, India. Forty six different sampling stations were selected for the study. Iron was analyzed by using an atomic absorption spectrometer, Perkin Elmer AA 200, while fluoride was measured by the SPADNS method at 570nm and Nitrate content was measured by the phenol-disulphonic acid method at 410nm using a UV–VIS spectrometer, Shimadzu 1240 model. The study revealed that the water sources in the area are heavily polluted with iron, and fluoride. Statistical analysis of the data is presented to determine the distribution pattern, localization of data and other related information. Statistical observations imply nonuniform distribution of the studied parameters with a long asymmetric tail either on the right or left side of the median.
