A method and system is disclosed for reversibly establishing a closed, flow-impervious cryogenic barrier about a predetermined volume extending downward from a containment site on the surface of the Earth. An array of barrier boreholes extend downward from spaced apart locations on the periphery of the containment site. A flow of a refrigerant medium is established in the barrier boreholes whereby water in the portions of the Earth adjacent to the barrier boreholes freezes to establish ice columns extending radially about the boreholes. The lateral separations of the boreholes and the radii of the ice columns are selected so that adjacent ice columns overlap. The overlapping ice columns collectively establish a closed, flow-impervious barrier about the predetermined volume underlying the containment site. The system may detect and correct potential breaches due to thermal, geophysical, or chemical invasions.

The method for reversibly establishing a closed cryogenic barrier confinement system about a predetermined volume extending downward beneath a surface region of the Earth, comprising the steps of: A. establishing an array of barrier boreholes extending downward from spaced-apart locations on the periphery of said surface region, B. establishing a flow of refrigerant medium in said boreholes, whereby the water in the portions of the Earth adjacent to said barrier boreholes freezes to establish ice columns extending axially along and radially about the central axes of said barrier boreholes, wherein the position of said central axes, the radii of said columns, and the lateral separations of said barrier boreholes are selected so that adjacent columns overlap, said overlapping columns collectively establishing a barrier enclosing said volume.
