In the current water crisis, the use of springs has helped to mankind in many areas. The application of indexes and statistical methods provide useful information for understanding water quality and planning for its proper management. When water resources have unique characteristics in addition to conventional use; this issue becomes more important, including the river, hot springs and Dehloran bitumen springs. In this study, 28 samples of hot spring water, 4 samples of river water and 4 samples of bitumen spring water were collected. The temperature, pH, EC, sodium, potassium and nitrate parameters were measured. One-way analysis of variance and one-sample T-test were used to compare the three regions and compare with WHO standard and Iranian national standard, respectively. Wilcox, WQI and INWQS indices were also used to classify water quality. Based on the results, bitumen spring water had a statistically significant difference with the other two regions in terms of all parameters and all parameters in the three regions had a statistically significant difference with WHO standards and Iran's national standard and lower than these standards. According to the Wilcox index, all specimens were unsuitable for irrigation; based on the data of the WQI index calculation, water quality can be classified as excellent quality and according to INWQS in terms of pH for aquaculture of sensitive species do not need treatment and in terms of nitrate are only suitable for irrigation. Considering the management and protection of the region as a national natural monument, it seems that the role of natural factors such as geology and the occurrence of floods in the chemical composition of water resources is much more important and based on the results of used methods with the exception of Wilcox index, the water quality was assessed as suitable. However, considering the health use of hot springs and the possibility of constructing welfare facilities for tourists, the role of human factors on the water quality of resources in the region should not be overlooked.
