In Situ Remediation Technology Status Report: Research and Application of Permeable Barriers
This document is an attempt to compile worldwide research efforts and applications in the field of permeable reactive barriers (PRB). The listing will evolve as input is received. Apologies are made for any inadvertent omissions or errors. Typically, many people are responsible for a project; however, for simplicity, a single contact is provided for each project. Research projects are organized by the type of contamination treated (organics or inorganics) and by the type of reaction process (sorption, precipitation, substitution, or degradation), and then by the specific material. Field projects are organized by state, province, or country. A PRB is defined by the Remediation Technology Development Form (RTDF) Action Team on Permeable Barriers as Aa passive in situ treatment zone of reactive material that degrades or immobilizes contaminants as ground water flows through it.@ Projects that appear to fit this definition are included.
