GCW-Stacked - Multiple Circulation Cells in one aquifer

The sphere of influence of GCW (Groundwater Circulation Well) depends on the distance of the two screen sections or, in case of a fully penetrating well, on the aquifer thickness. The larger the circulation cell is, the larger the travel time is for the circulation. For thick aquifers it may be beneficial to install several circulation cells, one upon another. This produces smaller circulation cells and shortens circulation flow time.

The hydraulic flow system can be combined with in situ stripping, an in-well treatment reactor, or any appropriate on-site technology. The use of multiple circulation cells in one deep aquifer may be also advantageous when the hydro-chemical properties of the soil and groundwater are drastically dependent on the aquifer depth.
