Hydrochemical behaviors of a karstic aquifer help to identify groundwater quality types within the extensive area of the reservoir. Classical bar, pie, trilinear and Durov diagrams are used extensively in the literature for such a purpose. However, in this research new techniques and procedures such as area concentration, frequency-concentration, ion-concentration percentage-frequency relationships are developed in the form of various charts for the identification of zonations and saturation of the groundwater in terms of various chemical constituents. Furthermore relative frequency-electrical conductivity and total dissolved solid relationships are obtained based on whether the groundwater is of sodium chloride, calcium chloride or mixture of the two types. Last but not the least, chemical equilibrium studies led to ionic strength-total dissolved solids-electrical conductivity relationships as well as the activity coefficient charts for major ions and cations. All of these techniques can be used in groundwater studies in any part of the world. The hydrochemical characteristics of the Umm Er Radhuma aquifer were investigated by the aforementioned new and classical techniques. The results indicated that the major groundwater types are sodium chloride and calcium sulfate. Umm Er Radhuma groundwater is saturated with respect to calcite but unsaturated for anhydrite in the northern part of the study area.
