DNAPLs such as chlorinated solvents, creosotes, and PCB oils migrate downward through both the unsaturated and saturated zones of the subsurface environment. Pump-and-treat methods will not achieve complete clean-up at DNAPL sites. The EPA's Technology Innovation office has identified technologies that hold promise for either treating groundwater in place or improving the solubility of contaminants to enhance pump-and-treat. This article briefly reviews in situ treatment, pump-and-treat enhancement, and enhanced recovery technologies. The correct solution will be varied and site specific. A new technology center at the EPA's Robert S. Kerr Environmental Research Laboratory in Ada, Oklahoma will serve as a clearinghouse for both public and private research into groundwater contamination.
