【 摘 要 】

The fact of pollution of the rivers Dezhnevka and Chulman, running in the zone of activity of the LLC "Kolmar" was recorded in May 2018. According to the results of the ecological surveys of the named above watercourses carried out by Ministry of Nature Protection of the Republic of Sakha (Yakutia), it was established that the main pollution was the result of the mine water discharge from the hydraulic system and industrial site JSC GOK "Denisovsky". As part of the integrated ecological monitoring the hydrochemical investigations of the river Chulman were carried out at 7 observation points in August of 2018. There were chemical and analytical works with the use of methods of potentiometry, titration, gravimetry, capillary electrophoresis, atomic absorption spectrometry, photometry and fluorimetry.
