ABSTRACT:
Treatment of flowable underground contaminants comprises freezing at least one open underground barrier volume to form a wall (10) near the contaminated region (12) in the ground (14), where the wall (10) is positioned to direct the contaminant flow (16) along a subsurface path (18) and allow concentration of the contaminants and their remediation.
