Iron and fluorine concentrations and water mineralization and hardness, which exceeded the maximum allowable concentrations, were found to cause an increase in overall morbidity and morbidity from skeletal-and-muscular, urogenital, and digestive system involvement in the population of the Krasnoyarsk Region. A quantitative relationship were found between the concentrations of iron, the hardness and dry residue of water and the incidence rates of urogenital, skeletal-and-muscular and digestive diseases. The consumption of potable water contaminated with chloroform and methane tetrachloride presents unacceptable carcinogenic risks to the population of the Krasnoyarsk Region.
