Аннотация: Over 90% of the territory of Iran is located in the regions dominated by the arid, semiarid and sub-humid climatic types with low rainfall rates or none at all. Subsequently, the study of the Iranian water resources, especially in the areas that face the challenge of water scarcity, is crucial. The present study focuses on defining the condition and the qual- ity of ground and surface drinking waters in the Delichai river-basin in Iran using GIS technologies and the Schoeller method, based on the semi-log scheme of the main ions con- centration (HCO –, SO –, Cl–, Ca2+, Na+, Mg2+, mg/l). TheThe main ions concentration in the ground and surface waters through-out the period proves the average quality (point of moderate danger) of the ground drinking water for all sub-basins: the excess content of Mg2+ – 82.66 mg/l (Iranian Standard,30 mg/l), SO – – 370.33 mg/l (Iranian Standard, 250 mg/l) 4Cl– – 366.33 mg/l (Iranian Standard, 250 mg/l), TDS 1582mg/l (Iranian Standard, 1000 mg/l), TH 272 mg/l (IranianStandard, 200 mg/l). The same for the surface drinking water: the excess content of Mg2+ – 52 mg/l (Iranian Standard,30 mg/l) SO – – 301 mg/l (Iranian Standard, 250 mg/l), TDS 41200 mg/l (Iranian Standard 1000 mg/l), TH 207 mg/l (Ira- nian Standard, 200 mg/l). Consequently, the surface and ground waters in the Delichai river-basin are in a moder- ately dangerous condition.
