National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract	The use of novel permeable reactive barrier (PRB) to remove and to stabilize heavy metals such as Cd and Cr from groundwater was studied. The barrier was made of fly ash, an appropriate material for high volume ion exchange. The fly ash is combined with chemicals to create activated ash material or AAM. PRB's, made from activated fly ash, AAM-PRB's, were used to treat contaminated water in situ. It was shown that the AAM-PRB was effective in removal of Cd and Cr from contaminated water, while at the same time utilizing waste fly ash that otherwise would be have to be landfilled.
