The entry of heavy elements into water and soil threatens biodiversity
According to Moj news agency
On the sidelines of a field visit to the Khazar field’s wastewater treatment system, Ali Selajgeh said: Usually, the process of iodine extraction is associated with soil and water pollution. In this complex, the sewage used to be discharged towards Inche Lagoon, but now, based on our observations and visits, a good scientific work has been done by the complex and they have tried to prevent the pollution of the lagoon.
He continued: Usually, the quarries of this region are associated with pollution of heavy elements, and if these heavy elements are injected into the water and soil sources, they will pose a problem to the biodiversity of the region, and when the rainfall is not enough and the wetland bed is dry, the emergence of this The elements that entered the wetland earlier increase the risk of dust.
Chairman Environmental Protection Organization He added: The General Department of Environment of Golestan Province, in cooperation with the Caspian deposit complex, carried out the measures related to the Shorabeh iodine sector, and with a transfer of about 11 kilometers, the effluent, whose amount was 160 liters per second, was injected deep into the ground up to about They inject 1000 meters deep.
The Vice President further said: As a result of the technical methods they used, there are about eight injection wells in this complex, which absorb this 160-liter wastewater. In terms of Rials, they have spent about 200 billion tomans, which in our opinion are positive actions, and they have started actions with the help of academics, which, of course, require more scientific work to be done here in terms of zoning and to fully determine the underground water tables.
Selajgeh added: If piezometric wells are created here, it can help with the issue of zoning, of course, through the same wells that have been dug, zoning can be determined quantitatively and qualitatively and the direction of underground water tables with a scientific method.
He clarified: If we have a hydraulic slope in the lower depths, especially the formation known as Baku in the region, the injection will be done under this formation, which will no longer affect our surface and deep water sources, and according to The hydraulic slope that is towards the sea does not cause any special problems in this part.
Head of the Protection Organization the environment He added: But in the discussion of the remaining 240 liters per second, the Caspian deposit complex must do its work as quickly as possible. Unfortunately, this amount is now being released into Inche Lagoon, which should be organized as soon as possible within a certain period of time. According to the approach that I see in the investor now, using scientific methods, this work will be done soon.
Stating that the rate of evaporation in this area is four times the amount of injection, he said: We must conduct a comprehensive survey of the surface and underground water resources of the area and see how we can use the wastewater treatment capacity in times like now when drought occurs. This area has been used. This study is now being done to see how much of this treated effluent is needed to adequately dewater the surrounding wetlands. Senior and doctoral students can carry out their study projects in this regard and the results of their work will definitely benefit the environment of the region.
The head of the Environmental Protection Organization explained: My colleagues continuously and permanently monitor the environmental activities of this complex, and the complex itself should help in setting up a monitoring station so that we can monitor the activities.
Stating that the Khazar mine is a strategic economic complex, the vice president emphasized: We do not want to stop the activity of the complex, but on the condition that the environmental concerns of the people, especially the environmentalists, are taken into account.
