Reclamation does not un-concentrate the materials found in the impoundment. Typically a "Mine Plan of Operations" which includes the reclamation plan is a contouring of the topography and vegetation. Some mines require indefinite groundwater treatment due to leaching from tailings ponds or other mine activity. The cost responsibility for this _indefinite_ process is sometimes borne by the state following bankruptcy of a mine.
