Abstract
The paper presents the investigation of iron-containing deposits at water treatment in the Tomsk water supply intake. The chemical composition of the waters facilitates the formation of deposits in a large amount on the territory of the Tom lower course. A large ground water deposit is located here, and it is used for Tomsk water supply. Currently, the deposit obtained at water treatment is discharged in the Kislovka, and this practice causes a serious environmental problem. The ways of deposit usage are offered in the paper, which will sufficiently increase environmental protection measures on the territory of the Tom lower course.

The high level of surface water contamination [1, 2, 3] promotes transition to underground water supply systems
Tomsk is provided with drinking water due to reserves of a major drinking ground water deposit, which is called «Tomskoye»
It is located in Tomsk region, in the northern part of the Ob-Tom interstream area [4]
Summary
The high level of surface water contamination [1, 2, 3] promotes transition to underground water supply systems. In Tomsk region the use of ground waters is in priority for drinking water supply. Tomsk is provided with drinking water due to reserves of a major drinking ground water deposit, which is called «Tomskoye». It is located in Tomsk region, in the northern part of the Ob-Tom interstream area [4]. A water supply intake started its operation in December, 1973. It consists of 198 operating wells arranged in three of its lines. The water supply intake gets out ground waters from the aquifer system in Paleogene sediments of «Tomskoye» deposit in the volume of 149.32 thousand m3/day [5, 6]. The use of deep-well water cannot solve the task of providing the population with the water of satisfactory quality
