     qualitative evaluation of water resources is the first step for having clean drinking water according to health standards and it is the requirement for properly designing of filtration processes. realization of this issue requires reliable and accurate information about the concentration and quantity of raw water quality parameters. in this research, the ground water quality of dehloran region was investigated in terms of anions and cations according to the monthly sampling data which was collected over 10 years in 3 wells in barebijeh region. in this study, the highest concentration level (ucl) (upper control limit) and the lowest concentration level (lcl) ) (lower control limit) were calculated based on t-test at 95% level and these values were used to evaluate the quality of drinking water according to 1053 national standards. the average of sodium concentration in wells 1 to 3 in barebijeh was 13.17, 13.01, 14.00mg\l and the average of calcium concentration was 21.57, 21.82, 22.11mg\l, respectively. also, the average of chloride in the mentioned wells was 11.89, 12.05, 12.79mg\l, the average of sulfate concentration in the wells was 10.13, 11.44, 12.04mg\l, respectively and the average of carbonate concentration in all wells was almost zero. the average of bicarbonate in the mentioned wells was 78, 77.76, 77.76mg\l, the average of nitrite concentration was 0.0003, 0.0009, 0.0003mg\l, and the average of nitrate concentration was 8.1, 8.48, 8.22mg\l, respectively. by comparing the calculated concentrations of ions according to the fifth revised edition of isiri 1053 of the institute of standards and industrial research of iran, the water quality of these wells is good for drinking.
