Abstract:
A multi-level fluid transfer system for remediating a subsurface area of ground having a contaminated area, the system comprising:a fluid source;a well comprising a well bore hole and first and second fluid transfer devices, the well bore hole extending down from the ground surface and having a side wall and a bottom;the first fluid transfer device having a first discharge section and a first riser conduit, the first discharge section being positioned within the well bore hole at a first level between the bottom and the ground surface, the first riser conduit extending up from the first discharge section toward the ground surface, the first riser conduit being connected to supply fluid to the first discharge section, the first discharge section including an outlet for the flow of fluid therefrom into the well bore hole; andthe second fluid transfer device having a second discharge section, and a second riser conduit, the second discharge section being positioned within the same well bore hole at a second level between the first discharge section and the ground surface, the second riser conduit extending up from the second discharge section toward the ground surface, the second riser conduit being connected to supply fluid to the second discharge section, the second discharge section including an outlet for the flow of fluid therefrom into the well bore hole;wherein no part of the well bore hole is used for extracting fluid from the subsurface area of ground.
