Abstract
To reduce the impact of alumina sludge storage on the environment, a number of environmental technical solutions have been tested and implemented. Laying a polymeric film on a bed slurry maps and the construction of artificial water level decrease led to the absence of anthropogenic interference, and created favorable conditions for ensuring the stability of the ecological system in the area adjacent to the sludge storage. After the implementation of the environmental events area negative impact of sludge decreased to 150–200 m from the contour of the slurry of the map, outside this zone there are qualitative changes in the chemical composition of groundwater, the alkaline reaction of the environment decreases less than 8.0 units, chemical composition of groundwater is virtually the same background.
