Russian and Finnish specialists in hydrological monitoring conducted research on Seleznevka and Buslovka rivers. This was the second joint monitoring of the SEVIRA project organized to share knowledge. The first trip was hosted by the Finnish side this May in Lappeenranta. Hydrologists took samples for further laboratory analysis and estimated the discharge – the volume of water flowing per unit time on the river section. This indicator is necessary to analyze the concentration of pollution in the river.

School river watch on Sestra river

In May 2019, the team of SEVIRA project conducted the first school water quality researches on Sestra river. In early May, the nitrate concentration in the area between Sestroretsky and Primorsky highways, as well as in the village of Beloostrov was insignificant, in the range from 0 to 10 mg/l with maximum permissible concentration of 45 mg/l.

Field work continues

Since April 2019, the Institute of Limnology of Russian Academy of Sciences has started to collect information on the nitrogen and phosphorous content in watercourses of Seleznevka and Sestra rivers. Based on satellite data, the Institute will create maps of various types of underlying surfaces of these catchment areas.

Roshydromet published the results of hydrological and hydrochemical studies on Seleynevka and Sestra rivers. According to the data received, between November 2018 and March 2019 there were no cases of high and extremely high water pollution  the rivers. At the same time, scientists found out that a high level of metals is a common issue for both rivers.

The results of the latest hydrological and hydrochemical studies are available now on the website of Roshydromet. There were no cases of high and extremely high water pollution in the waters of Seleznevka and Sestra rivers. However, the content of metals in both rivers was increased: aluminum, iron, copper and zinc.
