The fourth class of quality determined waters as “dirty” and the third class of quality means “seriously polluted” water object. According to information of the Ministry of nature management and ecology RB the river BOLSHOY IK and the lake KANDRYKUHL were admitted the most clean water objects in 2009. The river DEMA was called the dirtiest and the level of its pollution was referred to the fourth class as “very dirty”.
The most widely met contaminants, discovered in 50-100% of water tests were the organic substances, sulphate-ions, the compounds of iron, copper, manganese and oil products.
