The investigation has discovered two instances of unauthorised industrial water discharge from a recycled water sump, part of Talnakh Concentrator's tailings dam system, into adjacent area using flexible pipes and floating pumps.

The water samples taken from Talnakh Concentrator's technical water sump on 28 June indicated that the water discharge should not have any material impact on the environment and, most importantly, on the Kharaelakh River. An inspection survey conducted jointly with the Centre of Laboratory Analysis and Technical Measurements (part of the Environment Supervision Agency, "Rosprirodnadzor") has confirmed that there has not been any impact on the Norilskaya River.
