Claim:
1. A containment system for controlling the migration of fluid from a contaminate source comprising: a containment grid comprising a plurality of cooling channels, said grid defining a plurality of regions between adjacent cooling channels; an aggregate comprising frozen water and soil, said aggregate in thermal communication with the plurality of cooling channels and occupying the regions between adjacent cooling channels; wherein said containment grid is adapted to form a partial envelope around the contaminate source beneath the ground surface; a variable water permeable region in the containment grid; and a sensor for determining contamination; wherein the plurality of cooling channels form an hour glass shape, the hour glass shape defined by concentric circles with increasing diameters and increasing height above the variable water permeable region and concentric circles with increasing diameters and increasing vertical distance below the variable water permeable region.
