Purpose of research: to study dynamics of infectious and parasitic diseases (for 2008-2013 years) among children's population in the Dnipropetrovsk region and to define influence of water fac-tor on the disease and prevalence given class of illnesses. Materials and methods. Retrospective study of infectious and parasitic diseases (² class by ICD-10) among children's population from rural dis-tricts of Dnipropetrovsk region for 2008-2013 years was carried out. It was spent correlation analysis between some indicators of potable water quality of diseases of the given class in all districts. In the majority of rural districts, was shown increasing ² class of diseases from (1.4 to 1.63) times in dynam-ics for 2008-2013 years. In some districts was reveled an average correlation link between content in water of the dry residue, chlorides, sulphates, calcium, magnesium, except rigidity and iron and prevalence ² class of diseases (r=0.50, p<0.001). Prevalence of the given class of diseases was corre-lated with ðÍ, nitrates, oxidability in the three rural districts of Dnipropetrovsk region (r=0.74-0.89, p<0.001).
