Conclusion and proposals

We obtained experimental data indicate a lack of water quality for use in agricultural production. As an evaluation of water quality and water supply is an important component of modern welfare of livestock, poultry farms. The important direction of future research is to develop and justify passport assessment of water quality and water supply for consideration of biogeochemical zones, type of animals, their productivity and direct use.

Conclusion and proposalsComparison of monitoring the quality of

decentralized and centralized water supply sources of Bakhmach & Bobrovytsa districts of Chernihiv area found a significant difference between the level of protection of groundwater. Indicator are significant differences nitrate content, indicating a high contamination of aquifers livestock farm waste.

Water supply of villages and small towns of Ukraine, carried out mostly from decentralized sources are predominant in most ecologically dangerous because of high pollution vulnerable groundwater and lack of sanitary and epidemiological control.

Excess of established parameters total hardness, calcium content in all investigated decentralized water sources, which has an adverse effect on the body of animals and human health. Also not recommended to use such water in irrigation, as high salt content leads to salinization and land degradation.

In the studied objects should urgently carry out rehabilitation of wells, to enforce protective sanitary zones.
