To observe adverse health effects of heavy metals, drinking water samples (50) were randomly collected from Raja bolay village (RBV), Ghanakar village (GV), Deu khurd (DK), Kahna nau (KN), and Green cap housing society (GCHS). The results of physical parameters showed that mean pH and conductivity value of water samples of all the areas was greater than the standard value of WHO except in the samples taken from Deu khurd (DK). Mean value of TDS was greater than WHO in almost all the samples. Among heavy metals concentration of Cr was greater than standard value provided by WHO except in RBV (Raja bolay village) and GCHS (Green cap housing society). Cu concentration was lower than WHO standard value of Cu in drinking water. Mean concentration of Ni was very high in all drinking water samples. The population residing in Kahna nau had a high frequency of acute respiratory and kidney diseases, whereas skin diseases were common in the residents of Green cap housing society.
