Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "This study supports the ESD issue Conserving Canada’s Ecosystems (metals). ... The paper describes the results of batch tests, long-term column studies and mineralogical analyses conducted to assess the potential for in-situ reactive walls to remediate chromate contaminated groundwater. 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 and results of experiments conducted to assess the long-term potential of reactive walls for continued treatment of Cr(VI) are presented"--Management perspective. gccst Contaminated sites gccst Groundwater gccst Pollution control Ptacek, Carol Jane, 1959- Jambor, J.
