A GCW can also be operated in a way that a certain quantity of water passing through the well shaft is pumped-off or infiltrated into it. Extracting exactly the same amount of water as the upstream into the well, the groundwater downstream from the well is blocked.
Thus, at a remediation site, a complete hydraulic downstream protection of a plume of contaminants with simultaneous exclusive extraction of the injection groundwater can be realised. In addition, there is the possibility to extract water without changing the groundwater level in the well if a certain ratio is maintained.
