Assessing the potential of groundwater resources quality in the villages of Damavand city

Awareness of the quality of water resources is essential for assessing pollution trends for each region. The study area is located in the villages of Damavand city in Tehran, which is used to study the water quality parameters . Within 8 months , from January to August 2016, has focused on sampling and measuring physical parameters (Ec, TDS, turbidity, pH, hardness and alkalinity) of the water from 11 wells in the villages of Damavand city, which was chosen according to the location of the village's residential texture and its proximity to agricultural areas as sample wells. Also, by sampling and analyzing for two times, the quality of each parameter in the studied area and finally a qualitative map for each parameter was prepared. The results of this study suggest that given the fact that the southern marginal areas of Damavand area, especially the village of Wadan, have the highest concentration in most water quality parameters, this area can be considered as a narrow zone of high-risk man-made pollution hazard due to the rise of the rock floor and reduced permeability. In addition, the state of governance of the village of Wadan at the end of sedimentation basin has caused the role of the effectiveness of natural (geological) and hydrogeological factors in this section to be quite evident, the effects of which are increasing the concentration of physical parameters in this area. Due to the fact that some of the qualitative parameters have been observed in the groundwater resources of the area and, on the other hand, the only source of water supply in the Damavand area is groundwater, it is necessary that the quality of drinking water of the inhabitants of the area should always be considered.
