Purpose. Spatial analysis of ground water pollution for Kotovskiy district of Odessa region in 2015. Methods. Photometric, gauge, geographic information systems. Results. There are digital maps which show distribution of ground water pollution for Kotovsiy district. There are determined: maximum permissible concentration by oxidation in groundwater and artesian waters in nitrates were observed. The concentration of nitrates in groundwater varies between 2 – 4.9 MPC on over meadow territory and 25% of the territory – 7 MPC. Conclusions. The highest nitrate pollution of groundwater is typical for the eastern part of the Kotovsky district. It is proposed to reduce the amount of nitrate fertilizers, taking into account the vulnerability of groundwater to nitrate nitrogen based on the zoning of the level of contamination of the Kotovsky district of Odessa region.

Key factors of atmospheric air, surface and ground waters’pollution have been determined.Main directions in mapping of ecological conditions and environmental protection have been presented in the paper. Examples and contents of series of ecological maps of environment’s dynamic components of Kharkiv region have been given.
