ECOLOGICAL & HYGIENIC ASSESSMENT OF POTABLE WATER QUALITY IN THE KRYVYI RIH DISTRICT

Practical experience of research, carried out in the SE “Dnipropetrovsk Medical Academy Ministry of Public Health of Ukraine” covered the results of ecological methods usage in the field of preventive medicine. On the basis of Kryvyi Rih powerful iron mining enterprises (Ukraine) complex experimental research covering the long-term foundation of secondary landscapes on the dumps surface after mining exploitation process has been carried out. The poorer quality soils are dangerous for environment, surface- and groundwater, as well as human health. Under the influence of dumps quality of water taken from Karachunyvskyi reservoir dropped dramatically. Well water in the settlements, which are situated near the dumps, is forbidden for drinking purposes. Our data characterise priority in the sphere of potable water supply and main problem of water supply and potable water quality, actual for many regions of Ukraine, including Kryvorozskyi district - major rural part of Dnipropetrovskyi region, the population of which has been receiving potable water with deviations from hygienic standards in some indicators. Deterioration of qualitative structure of potable water with total hardness increasing by (1.55 – 1.29) times; sulphates by (2.23 - 1.84) times; manganese by (1.42 - 1,54) times; Na+-K+ by (1.18-1.11) times; Fe – by 1.71 times during 2008-2012 years in the territory of Kryvorozskyi district had been established
