The study dealt with analyzing the hydrochemical properties and the degree of karst solution of spring water in Ajloun Governorate, aiming to analyze the variation in the speed of karst solution of spring water in the spring and summer season, in addition to determining the ability of spring water to follow its karst activity. Statistical methods such as: testing have been used in the analysis process paired (t) test, correlation coefficient, and variance, in addition to the use of Geographic Information Systems (GIS). The study found a clear spatial and temporal variation in the karst dissolution speed of spring water. The difference between spring and summer reached about 7.81 mm/1000 years, and the results of paired (t) test indicated the presence of statistically significant differences (0.034). The spatial maps of the karst ranges also showed there is a clear spatial variation between the karstic ranges between the two seasons as the area of the rare and weak karst band increased at the expense of the medium and high karst band area. The study also revealed that the spring water was seasonally different in its ability to follow its karst activity at the moment when flowed to the surface.
