Technology Marketing SummaryScientists at the Savannah River National Laboratory have developed innovative processes for goundwater remediation.  The GeoSiphonTM offers significant advantages over pump and treat systems, funnel and gate systems, and continuous permeable wall treatment systems.  The GeoSiphonTM Cell is a passive, in situ, groundwater treatment system which uses a siphon between two points of natural head difference to induce greater than natural flow through a permeable treatment media.

GeoSiphonTM cells advance the current state of art for reactive barriers (i.e. funnel and gate) by using natural forces to accelerate the flow of contaminated groundwater through the treatment media.  The naturally acccelerated flow does not require any external energy input and reduces the time necessary for comoplete remediation.  Passive operation and reduced clean-up times can be translated directly into reduced operating and monitoring costs.DescriptionA GeoSiphonTM Cell was installed at the Savannah River Site (SRS) to demonstrate the technology for the remediation of chlorinated volatile organic compounds 9CVOCs), such as trichloroethylene (TCE), using granular cast iron.  Other CVOCs that were sucessfully degraded include, carbon tetrachloride and chloroform.Benefits
