The objective of this presentation is to describe how in-situ treatment using activated carbon reduces the bioavailability of certain chemicals of concern, discuss the Y Jetty/Lang Cove site considerations that factored into the decision to use activated carbon in an amended sediment cap, and describe the design criteria. This presentation will also discuss the implementation challenges and lessons learned during construction of amended sediment caps at the site.
