According to the researches, the water level in the Goryn River (above the Baltic Sea level) fluctuated within a month from 192.81 m to 192.69 m (by the end of month) in August. The average month temperature of water was 18.6°С. The average month water flow was 5.84 m3/s; the general flowing of the Goryn River was 15.14 million m3 during the month. The maximum daily average water flow was 4.37 m3/s, the minimum daily average water flow was 7.06 m3/s in August. The water level of the reservoir-cooler fluctuated from 202.40 m to 202.14 m (at the design level 203.0 m) during the month. The average month water temperature was 21.9°С (the maximum daily average was 25.9°С; the minimum daily average was 15.6°С). The mirror area of the reservoir-cooler was 18.213 km2; water volume was 97.940 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 August:

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 August 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 1.568 million m3 during August. The diversion flow from the Goryn River into the reservoir-cooler was performed at amount of ≈0.687 m³ 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 <0.020 mg/m3 (<10.0 % from MAC) in August. Based on the research of precipitation composition, pH value was 6.3 units. Total precipitation was 3.2 mm during August. (August 2016 - 11.1 mm; August 2017 - 46.1 mm). The average month air temperature was «+21.2°С» (the maximum daily temperature was «+24.6°С», the minimum daily temperature was «+16.5°С»).
