2. Background Rural sector consumes 40-45% of the volume of water that are removed from water sources to meet the needs of the population and industries, or 35-40% of water used in Ukraine. Water quality is the limited factor for other agricultural production areas as watering animals, cleaning of dairy equipment, food preparation, hydro cleaning, hygiene and household needs of staff. Low water quality affects cattle, causing illness, reducing the weight gain of animals and quality of livestock products. Watering and irrigation, especially drip one, are the keys to successful economic entity on earth. Low water quality can affect irrigated crops and soils due to: Accumulation of salts in the root system; Decrease the soil fertility; Migration of pathogenic organisms or contaminants (for example, Shigella, Lamblia)

3. Object of research Local water sources in Kyiv and Cherkasy region, which are used for drinking, household water supply and in agricultural production

4. Methods of research Chemical Physical- chemical

5. Monitoring parameters General chemical: Toxic:  Total hardness, μg-eq/L  Permanganate index, μ g O/L  N itrates, μ g/L

6. Investigated territories Kyiv regionCherkasy region Chabany-2 Khotiv-2 Khotiv-3 Khyzhyntsi

7. Indexes of Total hardness μg-eq/L (Cherkasy region)

8. Indexes of Total hardness μg-eq/L

9. Season Dynamics of Nitrates (Cherkasy region)

10. Season Dynamics of Nitrates (Kyiv and Cherkasy region)

11. Season Dynamics of Permanganate Index in Kyiv region water sources

12. INDEX OF WATER POLLUTION (IWP) ObjectIWP value Quality grade Description IVery clean IIIModerately polluted IIIModerately polluted IIClean IIIModerately polluted IIClean

13. Conclusions Water supply of the Ukrainian small communities of agrarian territories, carried out mostly from the local sources. Costumers haven’t any information about water quality. In general, local sources are ecologically and epidemiologically dangerous because of high anthropogenic pollution groundwater and unsatisfactory sanitary and epidemiological control. Detected additives are exceeding the guidelines for drinking and for agricultural use (irrigation, livestock, poultry drinkings).
