Tomsk region drinking water sources water quality monitoring

At present most Siberian rivers can't be used as drinking mater sources. Because of environment worsening the surface water became undrinkable, So, about 98 % of Tomsk region population use ground mater sources. Nevertheless Tomsk region water-hearing levels don't comply with requirements of drinking water state standards. In small villages of Tomsk region where is no centralized water supply the water is drawed from water wells. Ground water is used without any water treatment. Whereas in most of water wells the content of iron, manganese and hardness of water exceeds the admissible level several times. The main goal of this research work was the estimation of ground water chemical content and suitability for drinking water supply. We have researched drinking water sources of Tomsk region villages: Loskutovo, Timiryazevo and others. The analytical methods applied are: colorimetry, flame photometry and complexation titration. Experimental results show the iron excess concentration in every ater sample. In conclusion it should be noted that ground water of Tomsk region is suitable for drinking water supply. But we should recommend to use water purifiers in household or built deironing stations to decrease the iron concentration in ground water.
