According to the Regulation on monitoring and systematic evidence of the surface and groundwater status, the Beleu Lake is included in the network of surface waters state monitoring in the Republic of Moldova. The research results have marked a low value of the self-purifi cation capacity for Beleu Lake water, between 0.12 and 0.19, which is of 1.2-2 times lower than those from Prut River (0.25), correlating positively with the values of BOD5, COD-Cr and the time of biochemical oxidation of ammonium ions. The oxidation of ammonium into nitrite (NH4 (NH3) → NO2 -) in the nitrifi cation process in lake water (collected in November 2014) takes place about 25 days and the process NO2 - → NO3 - being more than 35 days. The period of nitrifi cation is about 2 times higher than in lake water collected in 2015 and 2.8-3.0 times higher than those of the model with water from Prut River.
