Pollution of water resources

On the territory of the Krasnoyarsk territory there are many lakes and rivers. As for the state of water, domestic and industrial wastewater significantly polluted the waters of the region. In the use of the population served poorly purified drinking water, which causes some diseases and problems.
The water quality of underground water sources is also unsatisfactory. Their chemical pollution is growing, bacteriological indicators improved until 2000, then deteriorated again.ich causes some diseases and problems.

The Mana river
Tourists love to visit the Manu, a right tributary of the Yenisei. It is a vast highly dissected high-raised plain on The Eastern Sayan, with numerous lakes and rocks.
White river is, what is still on mana rafting forest. Its bottom is covered with firewood, this reduces the importance of the river as a place of spawning and fishing, although there are 22 species of fish even under adverse conditions.

The river Kacha
Of the rivers of the left Bank of great interest is Kacha.Kacha eroded sedimentary rock strata and exposed dense igneous rocks in places.
Water Kachi, especially within Krasnoyarsk polluted by all kinds of industrial and domestic effluents. Here Kacha is more like a gutter than a river. There are projects to clean the waters of the river and the improvement of its banks, turning them into a green square, which at the mouth of the river would end with a vast Park.

Humanity, realizing that as a result of its life sometimes causes irreparable damage to the aquatic biosphere, is trying to find effective ways to purify natural waters from various kinds of pollution. Activities of this kind include the following types of actions:
industrial and domestic wastewater treatment;
disinfection of natural waters with the help of chemical reagents;
pumping of contaminated water into special reservoirs or aquifers;
development of technologies in the production of recycled water supply, which does not require additional water intake and runoff.

Our region has huge reserves of groundwater. They feed rivers in the winter season, serve as a source of water supply for industrial enterprises and utilities, and even represent the production raw materials in various chemical production processes.
But still, in our region is not so bad. There are many quite clean rivers: Big and Small Sliznevi, Laletina, Mokhovaya, Bazaiha.
