Description:
Air stripping, a traditional means of making slightly contaminated ground-water potable, is being applied increasingly to more severe groundwater pollution at remedial action sites. Concentrations of volatile and semivolatile compounds at such sites may reach hundreds of parts per million. As a result, several changes have resulted in air stripping technology. New air stripping technologies are being employed to achieve very high (>99 percent) removal of volatile compounds and to increase the removal of semivolatiles. New stripper designs are being investigated for compactness and mobility. In addition, emissions controls are being added because air pollution impacts are larger. The paper discusses these trends and provides examples from groundwater cleanup at remedial action sites in the United States.
