Aim and Background: Increasing population and urbanization, industrialization and inappropriate use of land have created numerous environmental challenges that contaminate water resources as one of its major implications. The discharges of wastewater and industrial wastewater at inappropriate places and the penetration of these effluent into the soil causes pollution of underground aquifers and subsequent pollution of well water. Underground water and rural water supply wells are more exposed to microbial and chemical contamination due to their remoteness from the urban service area. Therefore, in this research project, we decided to study and evaluate the amount of microbial and physicochemical pollutants of drinking water in Urmia wells.

Materials and Methods: This study was conducted within 6 months. Five sections, including the soomay baradost, the central part of Urmia, anzal, nazluo, and the Silvan section, were selected with the guidance of a respected expert from the West Azarbaijan Rural Water and Wastewater Company. The COD، BOD5, Total colifom (TC), Fecal coliform (FC) and Ecoli by The MPN method was measured and measured. Also, the probable chemical elements were measured based on Iran's standard organization protocols

Results: The results of physicochemical experiments showed that the samples taken on the basis of 1053 Iran standard organization have a desirable level. Also, regarding the parameters of fecal coliform, total caloric and E. coli, which are water resources pollution index, the results of all samples were reported from wells in selected villages without any contamination.

Conclusion: The results of the experiments showed that the well water in the selected villages of Urmia has a good level of microbial and chemical parameters, which indicates the effectiveness of the methods and policies applied in the management and monitoring of water resources.
