Civilian researchers completed a two-week field demonstration here Sept. 25 using an innovative plasma technology to degrade and destroy perfluorooctane sulfonate and perfluorooctanoic acid, known as PFOS and PFOA, in groundwater.
This was the first field demonstration of the Enhanced Contact Plasma Reactor, conducted under an Air Force Civil Engineer Center contract with primary contractor Clarkson University and teaming partner GSI Environmental.
Clarkson and GSI were awarded this research project to demonstrate effectiveness of a plasma reactor for the treatment of water containing PFOS and PFOA. Wright-Patterson AFB was the installation chosen for the field demonstration.
