Groundwater is an important part of the world's renewable water, accounting for about 60% of available renewable water resources. Due to the importance of this issue, this study was conducted to investigate the quality of groundwater resources in Kamyaran plain, Kurdistan. For this purpose, six effective parameters in determining water quality were analyzed. Then, by examining the Root Mean Square Error (RMSE) of two well-known interpolation methods (Kriging and Inverse distance weighted (IDW)), the IDW method was selected for zoning. The results showed that the electrical conductivity and total dissolved solids factors had many fluctuations in this plain and its range was identified for EC from 15000 µmhos/cm to 600 µmhos/cm and for TDS from 10200 mg/lit to 45 mg/lit. Using the drinking water quality standard, it was found that the concentration of the studied qualitative parameters in the groundwater resources of this plain, except for the pH parameter in some villages, is within the permissible range. Mainly the northern and southern parts of the plain have lower water quality. Therefore, groundwater resources quality planning and management of these areas is a priority.
