Permeable Reactive Treatment (PeRT) Wall for Rads and Metals. Innovative Technology Summary Report
Organic and inorganic contamination of groundwater is widespread at Department of Energy (DOE), Department of Defense (DOD), other federal, and industrial sites. Contamination at a majority of these sites is present in shallow, unconfined aquifers, which may impact human health and the environment. Although there are many treatment methods, for organic contamination, relatively few technologies are effective in treating inorganic contamination, such as metals and radionuclide, in situ. Because metals are commonly adsorbed to clays and organic matter in an aquifer, groundwater pump and treat technology can be expensive and ineffective. Desorption of these metals into the aquifer is a long-term issue, difficult to address. A permeable reactive treatment (PeRT) wall, also referred to as a permeable reactive barrier, is a zone of reactive material that is placed in a contaminated aquifer so that the concentrations of dissolved inorganic contaminants are reduced as the groundwater passes through the material. The reactive material can be emplaced directly in the path of groundwater flow via trenching or injection or as a reactive liner in a landfill. This document contains information on the above-mentioned technology, including description, applicability, cost, and performance data.
