Practical experience of research, carried out in the SE ‘Dnipropetrovsk Medical Academy Ministry of Public Health of Ukraine’ covered results of ecological methods usage in the branch of preventive medicine. On the basis of Kryvyi Rig powerful iron mining enterprises (Ukraine) complex experimental research covered long-term foundation secondary landscapes on the dumps surface after mining exploitation process carried out. The poorer quality soils are dangerous for environment, surface- and groundwater and human health. Under the influence of dumps quality of water taken from Karachunyvskyi reservoir dropped wildly. 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, which population
received potable water with deviations on some indicators from hygienic standards
