Analysis of Groundwater Isotopes and Ions Characteristics Relationship in the Area of Seawater Intrusion

Abstract:

This paper deals with the shortages of water-rock reactions affecting chemical evaluation. According to the results of isotope and chemical methods, established groundwater isotopes and ions characteristics relationship, in all ions, the decreasing order of correlation coefficient were K+&Na+ , Mg2+, CL-, SO42-, HCO3-, Ca2+, it indicating that different ability about ions to water-rock reactions. Finally, we select K+& Na+, CL- as the chemical parameters to routine monitor and evaluation, and CL- is reasonable for single index method, the critical value is 250 mg/L.
