Lead, oil products and zinc found in the rivers of the Magadan region
The Kolyma UGMS studied the state of surface waters in the Magadan Region and found that the rivers of the Okhotsk coast and Central Kolyma are contaminated with lead, oil products, copper compounds, suspended solids, manganese compounds, iron, zinc and hardly oxidizable organic substances. In this case, there were no cases of high and extremely high pollution.
According to the report on environmental pollution in the Magadan region for November 2019, the most polluted were the waters of the rivers Magadanka, Taui and Dukcha. Pollution, according to the UGMS, is mainly due to the activities of mining and housing and communal enterprises.
In 93% of cases, suspended solids exceeded acceptable quality criteria, in 86% of cases, copper exceeded acceptable quality criteria in the Taui River, in 71% of cases, petroleum products exceeded acceptable quality criteria in the Dukcha River, and in 44% of cases, lead exceeded acceptable quality criteria in the Magadanka River.
