Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The paper describes the mineralogy and mineral chemistry of longterm column studies conducted to assess the potential for in-situ treatment of chromate contaminated groundwater using permeable reactive walls. Chromium in the form of chromate is one of the most frequently encountered contaminants in groundwater. In the hexavalent form, Cr is highly toxic and carcinogenic. The study was initiated in 1992. Mineralogical analyses of reacted solids after flowing Cr(VI) contaminated groundwater through treatment materials for several years are presented"--Management perspective. gccst Contaminated sites gccst Groundwater gccst Pollution control Ptacek, Carol Jane, 1959- Blowes, David, 1956- Canada.
