Recirculation Systems

A recirculation system extracts contaminated groundwater from the site, adds to or amends the extracted water ex situ, and reinjects the "activated" water to the subsurface, generally upgradient of the contaminated zone. As an alternative, extraction and injection are performed at different elevations in a single well, creating vertical circulation. A groundwater recirculation configuration may be used to provide containment of a plume or to allow the addition of amendments in a more controlled environment.
