The purpose of this study was to compare the quality of water in Dez River in Taleh Zang's hydrometric station with the various national and international standards for the water used for drinking and agriculture sector. The method employed for conducting the research was descriptive-cross sectional. To study the quality and quality monitoring the water in Dez River, 392 samples were collected and analyzed, and then the results obtained from chemical analyzing of the water resources in the region were studied and interpreted. The obtained results were studied and compared according to the WHO standard, Scholler diagram and a number of tables and signs for determining the livestock drinking water quality. Most quality parameters have been of values within WHO allowable standard limits. Among all the quality variables studied, EC, TDS, pH, Ca, Mg, Na, So4 and Cl were within the standard limit and TH exceeded the limit. Regarding Scholler diagram, all studied parameters were evaluated as being well oriented. Using the agricultural classification of water, the Dez River was evaluated as being in the C2-S1 class. Furthermore, the quality of the river's water is suitable for livestock and poultry's drinking and is not problematic.
