摘要: A method for placement of remediation zones treatment contaminated groundwater in situ (10, 10A, 50, 60, 70, 80, 124) is described. The can be infiltrated or excavated and filled with a composition to provide the remediation. frozen wall (11) temporarily established by freeze pipes (16, 18, 16A, 18A, 51, 52, 61, 62, 72, 73, 74, 75, 84, 85) regions (120,122) around zone injection excavation filtration then created removed thawing. flows through zone, preferably using permanent barrier (86) acting as funnel. provides reliable economic situ.
