The National Monitoring Department for Environment of the Ecology and Natural Resources Ministry implemented the next monitoring for the purpose of review of the contamination level of Kura and Aras transboundary rivers, as well as transboundary affluences of them.
Water consumption in Kura river held 156 m3/sec in the first decade of September, increasing 17.1 m3/sec in relation to the second third decade of August. According to the results of the monitoring, the amount of bio substances in Kura river was considerably more than norm due to domestic wastes and slops of industrial enterprises discharged directly to water bodies without purification from the territories of Georgia and Armenia. Phenols and copper compounds as specific contaminants in the water composition exceeded the admissible turbidity level.
In this regard, phenols and copper compounds surpassed the admissible turbidity level thrice in Shikli-2 settlement, while for two and three times respectively in Agstafachay reservoir and Agstafachay settlement. According to the outcomes of the monitoring conducted in the first decade of September, phenols and copper compounds outnumbered the admissible turbidity level three times in Horadiz and I Shahsevan settlement, while twice in Bahramtapa settlement regarding Aras river.
The water oxygen regime fluctuated within the sanitary norm in all settlements containing 5.71-6.14 mg/l./eco.gov.az/
