Evaluation of Iron Sulfide Soil Formation Following Coastal Marsh Restoration - Observations from Three Case Studies
Abstract
Wetland restoration activities utilizing sediments, including dredged material, may induce formation of solid phase iron sulfide (FeS) materials. Under certain conditions subsequent oxidation of FeS materials can negatively impact soil pH, posing a risk to restoration success. As a result, procedures have been developed to document the presence of FeS using both field and laboratory techniques. This technical report evaluated conditions at three restoration sites, identifying FeS materials at a subset of sample locations. Guidance for evaluating FeS materials in a restoration context and associated management strategies are also discussed.
