Removal of contaminated groundwater/leachate for subsequent treatment at surface, followed by disposal. This technique can also be used as a groundwater control mechanism to produce a groundwater gradient thus possibly preventing unwanted migration.

Generally either pneumatically or electrically powered pumps uplift liquids from wells/collection trenches/cut-off trenches etc and pump the liquid through a treatment vent system to remove or reduce contaminant concentrations prior to discharge to sewer or possible re-infiltration to groundwater.

Can typically be installed as an unobtrusive system which can be extended over large areas. Capable of being adjusted to be more aggressive to control local groundwater levels. Depending upon ground conditions, the system often remains operational for extended periods to achieve criteria.
