IN SITU REMEDIATION

摘要

The in situ remediation in accordance with the principles of the present invention introduces into a contaminated environment a sufficient amount of permanganate modified with a sufficient amount of an activator so as to remediate a detectable amount of the contaminants. In one aspect of the present invention, the permanganate and activator form a manganese oxide or other mineral oxide barrier that at least partially encapsulates a portion of the contaminant to minimize or prevent migration and/or dissolution of the contaminant. This encapsulation occurs via physical encrustation. The in situ remediation reagents of the present invention can be added to any soil, sediment, rock, clay, water/groundwater and/or non-aqueous phase liquid environments via a number of methodologies such as for example subsurface injection, direct soil mixing, and the like.
