Abstract
There are several treatment technologies available for soils that have elevated levels of chromium. The technologies applicable to a particular chromium site depend on the clean‐up goals, the form of the chromium present, and the volume and physical chemical properties of the chromium‐containing soils. In many cases the clean‐up goals are based on the Cr(VI) concentration in the soils. Therefore, most of the available treatment technologies consist of (1) removing the Cr(VI)‐containing soils from the site, (2) immobilizing the chromium so that it will not leach after treatment under field conditions, or (3) reducing the Cr(VI) in the soils to the Cr(III) state. This article discusses the treatment technologies available for each of these remediation strategies, their advantages and disadvantages, and their relative treatment costs. Technologies evaluated include excavation and off‐site disposal, soil washing, soil flushing, electrokinetics, solidification/stabilization, vitrification, and chemical and bio...
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
