ЕКОЛОГІЧНА ОЦІНКА ПИТНОЇ ВОДИ ЛУГИНСЬКОГО РАЙОНУ ЖИТОМИРСЬКОЇ ОБЛАСТІ НА ЖОРСТКІСТЬ (ТВЕРДІСТЬ) ТА ВМІСТ ЗАЛІЗА

The ecologic assessment of the centralized and decentralized water sources of the Luginy district of Zhytomyr region on the hardness and iron ions contents is given. Possible organoleptic changes in water quality from high doses of these components and effects on human health are emphasizing. Drinking water has been analyzed for the content of iron ions and hardness in those settlements of the district where there are both a water supply system and wells, particularly in t. Luhyny, v. Myrolyubiv, v. Velykyі Dyvlyn, v. Lypnyky, v. Chervona Voloka. The researches were carried out during all seasons of the year, but there was no clear tendency to increase the concentration of the studied compounds depending on any of the season. It was found out that in water from centralized water supply the concentration of iron ions is much higher than in wells. By the hardness a reverse trend was observed. In the dynamics of 2014-2016 years was observed exceeded of DSanPiN standard in separate samples of drinking water over the content of iron during all three years that studied.
