According to the researches, the water level in the Goryn River (above the Baltic Sea level) fluctuated within a month from 192.85 m to 192.79 m (by the end of month) in June. The average month temperature of water was 22,4°С. The average month water flow was 4,93 m3/s; the general flowing of the Goryn River was 12,78 million m3 during the month. The maximum daily average water flow was 3,56 m3/s, the minimum daily average water flow was 6,44 m3/s in June. The water level of the reservoir-cooler fluctuated from 202.35 m to 202.18 m (at the design level 203.0 m) during the month. The average month water temperature was 25,5°С (the maximum daily average was 28,7°С; the minimum daily average was 23,0°С). The mirror area of the reservoir-cooler was 18,848 km2; water volume was 103,096 million m3 at the end of the month.
The chemical analysis data of water quality in the reservoir-cooler (the pump station of auxiliary water) and in the Goryn River (near the Old Mill, Netishyn)were as follows in June:

Notes: Standard MAC (maximum allowable concentration) is applied for water objects of industrial fishing (the Goryn River pertains to them) - «Rules of superficial water protection» (approved by the Order of the State Committee of Nature of the USSR dated 21.02.1991).

According to the data of chemical analysis results mentioned above, the water quality of the reservoir-cooler in June was better than the water quality in the Goryn River regarding many coefficients.
The water recovery from the drainage channel of the pump station of leakage water was 1,51 million m3 during June. The diversion flow from the Goryn River into the reservoir-cooler was not performed by the pump station of auxiliary water.
According to the data of ambient air composition research, the month maximum one-time concentration of oxide sulfur at the border of the protected sanitary area of KhNPP (in Neteshin) was <0.05 mg/m3 (<10.0 % from MAC), the maximum one-time concentration of oxide nitrogen was <0,02 mg/m3 (<10,0 % from MAC) in June. Based on the research of precipitation composition, pH value was 6,8 units. Total precipitation was 43,9 mm during June. The average month air temperature was «+19,7°С» (the maximum daily temperature was «+26,0°С», the minimum daily temperature was «+12,6°С»).

The total rainfall for the first half of 2016 was 215.8 mm (247.1 mm for the same period of 2015).
