Nowadays, because of severe droughts, the drilling of new wells, the over-abstraction of groundwater resources, and inattention to resource planning and management, there is an urgent need for paying special attention to groundwater resources and their quantitative and qualitative assessment. The present research assesses the quantitative and qualitative status of groundwater behavior in the Shourdasht basin of Qahavand in Hamadan province, Iran. Quantitative and qualitative groundwater data were collected for the 2001-2016 period and the quantitative and qualitative groundwater maps of piezometric wells data were evaluated using the GIS-based interpolation method. According to the results of the annual Shourdasht hydrograph, an average of 1.7 m decline is observed in the groundwater in the study area. The calculation of hydrodynamic coefficient shows that the studied aquifer had the maximum water transmissibility rate of about 165.23 m/day in the northwestern part of the Shourdasht basin and the minimum transmissibility rate of 16.5 m/day in the north of the basin. The maximum and minimum specific yield coefficients were recorded in the eastern and northeastern parts of the plain, which were about 0.61 and 0.006, respectively. The results of the qualitative study of the area show that according to the Schuler diagram, drinking water quality is mainly within the acceptable to moderate range. Also, according to the Wilcox diagram, the samples are classified to have medium quality.
