From environmental health hazards, chemical hazards are given priority. The mineral deposits in the Bolnisi-Dmanisi region significantly pollute the environment. This fact is confirmed by our work, because cadmium and lead in the control points did not exceed the permissible concentration in any season. Concentrations of pollutants in the river are not always the same because the volume of wastewater from the plant is always different. This process is therefore difficult to control and correlation is difficult to establish. Also, this process is characterized by seasonality (during the period of abundant atmospheric precipitation in autumn and spring, a large volume of water flows) and it is difficult to accurately calculate the water flow, at which time polluted water from the slopes is mixed with the river Mashavera.
