Sealing Boreholes in Rock Salt,s need to be protected from potential contamination. In the undisturbed geological system, potential contaminants are separated from freshwater aquifers by low-permeability aquitards including evaporite deposits such as bedded and domal halites. Improper plugging, sealing or abandonment of boreholes
