Transferring Laboratory Success into the Field.

Initial Research, and the Hunter`s Point and Grasse River Pilot Studies

The early research on using sorbents such as activated carbon to reduce the bioavailability of contaminants in sediment followed the use of these materials for removing chemicals from water.  Laboratory experiments shown significant reduction in the uptake and toxicity of hydrophobic organic chemicals to benthic organism

Bailey`s Creek Pilot Study

In 2009, the first commercially-produced SediMite pellets were applied to a small test plot of PCB-impacted sediments of Bailey`s Creek, a brackish intertidal salt marsh system. Pre- and post-application samples were analyzed for sediment contaminant concentration, carbon content, benthic community, and bioavailable portion of the contaminants using passive samplers and laboratory bioaccumulation assays.

Activated carbon delivered vi

SediMite was applied in two locations of Canal Creek, Aberdeen Proving Ground as part of an ESTCP-funded field pilot study to test the efficacy of activated carbon in remediating sediments in-situ.

Test and control plots were established in two portions of Canal Creek: a tidally-influenced freshwater marsh in the upper creek and a brackish creek channel in the lower portion of the water body. Pre- and post-application samples were collected and analyzed to determine the effects of act

Deleware Department of Natural Resources and Environmental Control (DNREC) implemented an ambitious plan for reducing the fish tissue concentrations of PCBs in Mirror Lake, Dover, DE with the goal of removing fish consumption advisories from this water body and further downstream.

About 80 metric tons of SediMite was applied to the 5-acre Mirror Lake in 2014. DNREC has produced a video describing the project and showing the application. A second video describes the one-year monitoring

SediMite® was one of three activated carbon (AC) amendments used in a field pilot study in the Berry’s Creek Study Area (BCSA) in the Hackensack Meadowlands of northern New Jersey.  Sediments in intertidal marshes of the BCSA are dominated by Phragmites reed and contain PCBs, mercury and other contaminants.  A resulting fish consumption advisory is in effect due to PCBs.
