1. A method of treating flowable contaminants beneath a surface region in the ground comprising:
- freezing at least one, open subsurface barrier volume of earth in the form of a wall structure near the contaminated region, and positioning the frozen barrier such that the flow of contaminants is directed along a predetermined, subsurface path causing concentration of contaminants.

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.

6. A method of treating flowable contaminants beneath a surface region in the ground, characterized by:
-
(A) freezing a subsurface barrier volume of earth, having two end portions and a central portion, partly surrounding the contaminated region and vertically extending to an impervious strata layer; (B) positioning the frozen barrier to allow a flow of contaminants within the subsurface barrier through an opening between the two end portions of the barrier in a manner to concentrate the contaminants; and (C) concentrating the contaminants. - View Dependent Claims (7, 8, 9)
