Ecological state of the small river in the Moscow Area after nutrients removal unit commissioning


The results of monitoring the ecological state of the Pekhorka River (the Moscow Area) on the hydrochemical and hydrobiological water quality parameters are presented. The river water contains more than 90% of the Lyubertsy (Moscow) wastewater treatment facilities effluents. The nutrient removal unit retrofitted into the treatment process was commissioned in August 2006. The regular ecological monitoring carried out by Mosvodokanal OJSC staff showed that from that moment the nitrogen concentration in the river water downstream of the treatment facilities discharge decreased by more than 30%, and that of phosphorus – by 50%. Beginning from 2006–2007 till the present moment the increase of phyto-and zooplankton species diversity has been observed.
