WATER QUALITY OF THE KAPARAS AND CHANNEL RESERVOIRS AT THE TUYAMUYUN HYDRO COMPLEX
The country's available water resources are consumed by various sectors of economy, such as industry, agriculture, energy, communal services. Due to the limited water resources, there are problems in proper water supply to the population. The article provides an assessment of the degree of mineralization and basic ions in the water of the Kaparas and Channel reservoirs based on field studies and laboratory analyses taking into account water volumes in the reservoirs and changes in water level. At the same time, it was identified that water quality exceeds standard indicators. For example, at using water for irrigation purposes salinity was high, and when for drinking purposes, the indicators of sulfates, chlorides and overall hardness in the autumn-winter periods and in spring are high, and indicators of organic substances and phenols higher 10-30% than normal during the year. The recommendations have been developed for improving of water quality taking into account of the reservoir operation mode improvement. Improvement of the water quality of the Kaparas reservoir for drinking water was determined by improving the existing operation of the reservoirs.
