Groundwater quality from different water supply sources of the Khorostkiv territorial community of Ternopil region
Abstract
Purpose. Analyse the quality of groundwater from different water sources in the Khorostkivska urban territorial community.
Methods. System and statistical analysis, geochemical groundwater quality assessment method and titration method.
Results. It has been established that the structure of water use in the Khorostkivska community is dominated by the use of water for drinking, sanitation and production needs. The main sources of water supply are surface and groundwater. The qualitative parameters of samples of tap water from of the Khorostkiv city, three private wells and three public wells within the community and five wells of private households in the village of Verkhivtsi of the Khorostkivska territorial community were investigated. It has been established that the sources of centralised water supply of the Khorostkiv city do not meet the requirements of Sanitary-Epidemiological Norms 2.2.4-171-10 in terms of ammonium nitrogen and chromaticity. Exceedances of nitrate nitrogen and overall hardness parameters were observed in water samples taken from the public well in the Khorostkiv city at 4 Muzejna Street. The results of determining the overall water hardness in the wells of private households in Verkhivtsi village showed that two out of five samples exceeded the standard values.
Conclusions. The water quality of the main sources of water supply in the community generally meets sanitary and hygienic and environmental standards, however, there are risks to the quality and safety of surface and groundwater. In order to prevent contamination of groundwater, it is proposed to restore the operation of treatment facilities in the city of Khorostkiv, provide rural settlements with a centralized water supply system, and control the removal of wastewater from private households.
