ABSTRACT:
A method and machine are disclosed herein for cleaning and restoring sand beaches which have become contaminated by oil spills. The machine travels on the beach and sprays liquid nitrogen onto the contaminated area, thereby solidifying the oil and sand mixture so that the mixture can be separated from the underlying uncontaminated sand and be efficiently removed from the beach and transported to a remote site for disposal or further treatment.
