Hydrologists have paid attention to identify the in fluential factors on underground water quality to examine the source of salts. In this research, hydrochemistry and the source of underground water salts in Sarchahan plain were examined using ion ratios and the difference between densities of ions of the same source. In a phase in 1998,49 Samples from the aquifer and 13 samples from the surface water of Sarchahan plain were provided. Then some ions with common mineralogy source namely twin ions were identified and the imbalance between them was considered as a sing of subsidiary factors and processes affecting Sarchahan aquifer quality. The examination of the relationship between twin ions with the help of ion differences of CL-Na and So4(ca+Mg) can provide the possibility of identifying the affected region from dissolution of compound such as Manesium in Sarchahan aquifer. Generally, the examination of ion ratios and the difference of twin ions show that the dissolution of Halite and Solfate salts of alluvium can be the main factor of salinity of underground water in Sarchahan plain. Oppositely, Por Abedin river Causes improvement of Chemical quality of Sarchahan aquifer but Shoor river has no effect on Salinity increase of aquifer due to underground water drainage. Furthermore, natural softening processes and opposite softening affect the quality of this aquifer as well and by extending the salinity toward downstream areas the possibility of occurrence of opposite softening increases. The possibility of Dedolomitization in Sarchahan aquifer is out of question. Additionally, salt domes do not have a clear effect on salinity of underground water too.
