Evaluation and presentation of solutions to reduce heavy metals in groundwater of Garmsar plain

Iran is one of the water-scarce countries in the world. The management of available water resources is one of the most important issues in water engineering. Part of the water in the surface and underground is combined with heavy metals and their quality is reduced. This article examines the quality of water resources in Garmsar plain. The required data was obtained in the field from wells and soil of the region and GMS software was used for modeling. In the following, a solution is presented to improve the existing situation and the result is compared with the current situation. The results showed that Scenario 2 had the greatest impact on the reduction of heavy metals and on the other hand Scenario 4 had the least impact on the values. If the solution is used, the amount of heavy metals in the water of Garmsar plain will be reduced.
