Background& Objective: Today, it is very important to pay attention to the quality of groundwater and its trends for various uses of drinking, agriculture and public health. Water is essential adequate and desirable for these uses. The aim of this study was to determine the physical and chemical parameters of water in Darrehshahrcity and comparison with national and international standards and analysis using the relevant software for Different Consumption.

Materials & Methods: To do this study 21 numbers of water samples were collected from 7 different stations in Darrehshahrcity and all parameters were analyzed according to the standard method of 2005 by device and titermeter. For data analysis, descriptive statistics, charts Piper, Schoeller, Wilcox and statistical tests were used.

Results: The mean value of turbidity, electrical conductivity, total dissolved solids and total hardness, were 1.4NTU, 438μ mhos/cm, 277mg/l and 144mg CaCO3/L  respectively and also the mean value of nitrate, nitrite, sulfate, chloride, fluoride, calcium, magnesium, sodium, iron and manganese were 4.7 mg/l, zero, 31mg/l, 4.4mg/l, 0.3mg/l, 62.7mg/l, 12.76mg/l, 4.4mg/l, 0.03mg/l and 0.003 mg/l respectively.

Conclusions: The results showed that all the investigated physico-chemical parameters were within the limit of   water standard of Iran (1053), drinking water standards of World Health Organization and other International Standards. Schuler diagram indicate that Darehshahr water is in a good range for drinking and Wilcox diagram show that Darehshahr water is slightly salty waters (C2S1) and almost appropriate for agricultural purposes.
