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 104 m3/sec in the first decade of October, increasing 23.6 m³/sec in relation to the third decade of September. 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 trhice and quadruple in Agstafachay and for four times respectively in Agstafachay water reservoir.
According to the outcomes of the monitoring conducted in the first decade of October, phenols and copper compounds outnumbered the admissible turbidity level for four times in Horadiz settlement, while phenols and copper compounds outnumbered admissible turbidity level thrice in I Shahsevan and Bahramtapa settlements regarding Aras river.
The water oxygen regime fluctuated within the sanitary norm in all settlements containing 5.82-6.13 mg/l./eco.gov.az/
