Phytoextraction of chloride from a cement kiln dust (CKD) contaminated landfill with <em>Phragmites australis<\/em>. J. Waste Management 51: 111-118.&nbsp;<\/p>\n\n\n\n<p>Cement kiln dust (CKD) is a byproduct of cement manufacturing that contains chloride.&nbsp; When disposed of in landfills, the chloride ions seep into water sources where they are toxic to plants and aquatic life.&nbsp;This study explored the common reed (<em>Phragmites australis) <\/em>as a low-cost strategy to remove chloride from a CKD landfill in Bath, ON.&nbsp;Reeds are very tolerant to high levels of salt in soil, and they take up chloride and store it in their shoots. At the end of the growing season, the chloride-containing reeds are cut.&nbsp;They may be transported to landfills that prevent leaching into waterways or may be composted before removing the chloride.<\/p>\n\n\n\n<p>Based on the study, it would take 3-9 years to remove chloride from the soil at the landfill using common reeds with low levels of disruption to the existing ecosystem.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<ol style=\"list-style-type:1\">\n<li>Students collect natural materials typically found in a wetland area to construct their own water filter.
