In the all rural tacsons of Dnepropetrovsk region a common tendency - high salt composition of potable water from centralized water sources is observed: general rigidity, dry residue, chlorides, sulfates, calcium, magnesium, iron. The highest content of general rigidity was shown in the water of 1st tacson: from 143 to 21.2 of MAC for 2008 - 2014 years' period (p<0.001). Thus, in water samples the of 1st tacson high dry residue content (from 1.38 to 1.04) of MAC, chlorides (from 1.64 to 1.14) of MAC, sulfates (1.06 of MAC) (p<0.001) were determined.
