According to the researches, the water level in the Goryn River (above the Baltic Sea level) fluctuated within a month from 192.75 m to 192.68 m (by the end of month) in January. The average month temperature of water was 0.8°С. The average month water flow was 9.15 m3/s; the general flowing of the Goryn River was 24.51 million m3 during the month. The maximum daily average water flow was 7.15 m3/s, the minimum daily average water flow was 12.7 m3/s in January. The water level of the reservoir-cooler fluctuated from 202.02 m to 202.06 m (at the design level 203.0 m) during the month. The average month water temperature was 4.7°С (the maximum daily average was 7.6°С; the minimum daily average was 1.3°С). The mirror area of the reservoir-cooler was 18.431 km2; water volume was 99.478 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 January:

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 January 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 1.676 million m3 during January. The diversion flow from the Goryn River into the reservoir-cooler was performed at amount of 1.413 mln. cub. m 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 January. Based on the research of precipitation composition, pH value was 6.40 units. Total precipitation was 30.9 mm during January. The average month air temperature was «-5.0°С» (the maximum daily temperature was «+0.6°С», the minimum daily temperature was «-18.2°С»).

The total rainfall in January was 30.9 mm (47.2 mm - January 2015; 39.3 mm - January 2016).
