On cover page, "dentrification" should read: denitrification. Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "Nitrate is usually the principal nutrient present in septic-system groundwater plumes. In aerobic aquifers, nitrate can migrate long distances from tile beds and can lead to degradation of drinking water supplies. The Waterloo denitrification barrier is an altemative treatment system for removing nitrate from flowing groundwater. An organic-carbon rich zone is installed in the path of the migrating groundwater to promote denitrification reactions and nitrate removal Partial to nearly complete removal of nitrate from flowing groundwater is demonstrated at a number of field sites"--Management perspective. gccst Groundwater Denitrification Blowes, David, 1956- author.
