The National Monitoring Department for Environment of the Ministry of Ecology and Natural Resources (MENR) 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 501 m3/sec in the third decade of April, decreasing 277 m3/sec in comparison to the second decade of April. According to the results of the monitorings, 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 and quadruple in Shikli-2 settlement and Agstafachay reservoir, while twice and thrice respectively in Agstafachay settlement.
According to the outcomes of the monitorings conducted in the third decade of April, phenols and copper compounds outnumbered the admissible turbidity level thrice and fourfold in Horadiz settlement, thrice in I Shahsevan settlement, while twice and four times respectively in Bahramtapa settlement regarding Aras river. The water oxygen regime fluctuated within the sanitary norm in all settlements containing 5.0-5.70 mg/l./eco.gov.az/
