Abstract :
The study region is Shiraz and Gharehbagh plains in Fars province. Most significant water requirments,especially drinking water in these regions supply are supplied with groundwater resource. In order toestimating of Arsenic contamination between water resource of the region has been done sampling from25 resource during 4 periods in a year. These sample were analyzed with ICP method. After laboratoryinvestigating and the comparison of outcomes to WHO standard detected highly contamination withArsenic in groundwater. With using of contamination zonation maps of Arsenic concentration in theseregions distribution of this element could be observed easily. The distribution of the abovementionedelement has not equal in different periods of sampling but significant point is increasing of itsconcentration at 2-3 month after sufficient rainfall.
