River Biosystems Monitoring

There are more than 60 thousand rivers and streams on Sakhalin. When the industrial infrastructure was under construction, the Company built crossings over more than 1,000 water bodies.

Monitoring programmes provide an opportunity to control the quality of surface water and bottom sediments and to assess the impact of the facilities on waterways and ecosystems. The opposite effect of the environment on the integrity of the engineering structures was also revealed.

The pipeline crossings of streams generally do not affect the quality of surface waters as well as their flora and fauna.

In 2013, the Company published the book entitled The Rivers of Sakhalin with information about the rivers of the island and the measures undertaken by the Company to minimise its impact on them
