Citizens of Saint Petersburg have been worried about the problem of "color river" for 3 years. There is a plant near the river producing polyethylene. In 2016 one criminal case was initiated by the committee of nature management for company "Ecoprom". It was found out that the concentration of wide range of chemical substances exceeded.
It is not the only case of horrible chemical pollution in Saint Petersburg. For opinion of Russian eco-volunteers, there are so many situations, сonnected with color rivers and lakes, located in Leningrad Oblast. They consider that the water from open reservoirs is dangerous not only for drinking, but for swimming too.
What solutions can we offer?
Institute of Earth Sciences. The first laboratory in Saint Petersburg with the 15-year experience in studying water, soil and air pollution
Complex equipment chemical analytical complex allows for the identification of small molecules of different nature, trace elements and "heavy metal", to carry out research of biological components and morphological structures, including biological contamination.
Bioelectronic complex is equipped with marine and freshwater aquariums for extended periods of aquatic organisms. The complex has:
polar aquarium (water temperature from 4 to 12 °C);
moderate aquarium (water temperature 16 to 21 °C);
tropical aquarium (water temperature between 22 and 28 °C).
The main scientific results of this researh:
1. water in open reservoirs of the sity and region contains 10-45 mg/l of nitrates which is normal for ecological situation - these reservoirs are purified by the system of Vodocanal;
2. the water in springs of Leningrad Oblast contains 200-250 mg/l which is dangerous for human health
"We just write scientific articles about the results of research"
Dmitriy Samulenkov, PhD of geology science about his unique experiments in protecting water from pollution and waste
"Our laboratory has successful location in the centre of St. Petersburg, which provides effective opportunities for gathering empiric material - air, water and soil samples - and covering most of the city's territory".
A mobile lidar complex on the basis of the vehicle and stationary lidar complex, located in the astronomical tower of the Faculty of Geography and Geoecology. This module allows you to get the results of lidar sensing that appear on the screen in the form of aerosols, the size of their particles, the content of variable gas, the vertical profile of wind speed and direction, which allows to determine the direction and speed of the spread of pollutants.
The main government organization which purify the water in canolizations of Saint Petersburg
Vodokanal has been operating a unique two-stage technology for complex disinfection of drinking water at waterworks
It involves the use of a highly effective and simultaneously safe reagent - sodium hypochlorite (chemical method) and ultraviolet water treatment (physical method). This combination allows to fully guarantee the epidemiological safety of water supply in St. Petersburg,
The results of purification
The main controversies in water purification process
We control only canalization system and wastewater system in St. Petersburg but don`t control system of plants and factories. All these "red" and "black" rivers appear because of metal particles and chemical waste thrown by these plants
Manager of technological development of the Department of environmental protection
"Vodokanal" is working with Helsinki Comission on improving the environment in Baltic region. But the problem of microplastic in water isn't important for St. Petersburg. We can't differ microplastic from plastic in official documents and haven't measured the negative impact of microplastic on eco situation yet.
"Beautiful Saint Petersburg"
One of the strongest eco-movements in St. Petersburg tries to change the ecological situation of the region
We can collect plastic bottles and waste for hours but there is no guarantee that tomorrow lake will be clear. Who is responsible for this catastrophy - officials or our citizens?
