ABSTRACT
The adverse effects of artificial recharge of desalinated water on the Dammam Formation aquifer in northwest Shigaya was studied using several techniques. The porosity and permeability of the core samples were measured in the laboratory, and a statistical analysis of the available hydrogeological and hydrochemical data was carried out. The porosity and permeability values were found to be controlled by lithology. Significant reduction in permeability was observed when the water flowing through core samples was loaded with different concentrations of bentonite clay.
