Studies on heavy metal pollution in groundwater resources have been carried out due to human need for drinking water through wells. There are several heavy metals in groundwater as Arsenic, lead, Cadmium, chrome, mercury etc. Investigating the heavy metal pollution of groundwater resources as a source of actual results based on the results of chemical analyzes in different time periods (wet periods and droughts) and its implementation in the GIS system and analysis in the qualitative study phase, is a common method in this research.
Theoretical motive for such studies is the GIS map as a model for changing the physicochemical parameters and its practical motive for policy making for water harvesting, drinking water treatment and contamination, and attempts to prevent it from growing in different regions. Part of this research is to study the researches of Iran and the world with the approach of studying groundwater with different methods for information interpolation, use of various indicators of water quality. The results of this research will be in the form of summarizing the methods and views of the active researchers in this field, the ability to create the idea (idea) and the method of work for future research in the same field.
