Study of heavy metal pollution of natural waters of Bolnisi Municipality and maintaining their biodiversity.
2020
In 2019-2020, the physico-chemical, hydrochemical and microbiological characteristics of the natural waters in the vicinity of the Madneuli ore plant were studied, taking into account the issues of biodiversity control and conservation. There was an increase in the content of heavy metals - Cd, Fe, Zn and Cu in excess of the maximum allowable concentration in natural waters; the rest of the heavy metals were within the norm; high iron content in drinking and artesian water has been identified; special load falls on the river Kazretula. In 2020, the enterprise encapsulated the river. As a result, the biologically dead river revived is niw clean, which is evident ere the river water is treated and the fact that the dirtiest river, where the wastewater from the plant falls and which was a biological can be visually observed and confirmed by a microbiological analysisr.
