This manual is a guide to the use of in situ reactive amendment technologies for remediation of contaminated wetland hydric soils, providing a toolbox of methods with which to approach site characterization/monitoring, treatability testing and demonstration, and remedy implementation. This manual (1) provides a repository of literature sources for active in situ remedial projects; (2) outlines a conceptual approach to managing the remediation of wetland hydric soils; (3) offers suggestions for project objectives, metrics, and evaluation criteria; (4) discusses implementation means and methods; and (5) supports an assessment of technology cost. This guide is based upon a field demonstration conducted at Aberdeen Proving Ground to determine the most effective amendment to immobilize PCBs in wetland sediments among the following agents: powdered activated carbon slurry (Slurry Spray), two pelletized AC products (AquaBlok® and SediMite™), and an engineered manufactured soil cover system (sand control). https://www.estcp.com/content/download/40731/389691/file/ER-200825%20Framework%20Guidance%20Manual%20In%20Situ%20Wetland%20Restoration%20For%20Posting.pdf
