WATER QUALITY ASSESSMENT OF UNDERGROUND SOURCES OF DRINKING WATER SUPPLY IN VINNYTSIA REGION

Abstract

The estimation of the quality of underground waters was performed of prevailing on the territory of aquifer complex in the area fractured zone Precambrian crystalline rocks as the sources of drinking water supply of Vinnytsia region based on the most current approaches on the example of the representative area of Vinnytsia region. 

The received results allowed to characterize the underground waters as “excellent”, very clean according to the  blocks organoleptic, microbiological, parasitological indicators and indicators of radiation safety (class 1), which fully satisfy regulatory requirements for drinking water; as transitional in quality from “excellent”, very clean to “good”, clean according to the blocks of toxicological indicators of the chemical composition of water and general sanitary of chemical indicators (class 2).

A general list of priority indicators of water quality was established, which will be determinative when choosing modern methods of water conditioning. It was found out that these ones included total water hardness, total iron, manganese and a range of toxicological components, natural level of which corresponded to class 2 in quality, but exceeded regulatory requirements for drinking water (aluminum, nickel, lead). According to the established priority indicators modern methods of intensification of the processes of water conditioning were offered. Those methods can be used during production and exploitation of groundwater sources.
