Description of Contaminant Sediment-Water Interactions Using RECOVERY (2006)

Sturgis, Thomas C., Ruiz, Carlos, Gunnison, Douglas, Pennington, Judith C.

Bedded sediments serve as sinks for many contaminants. Deposition of contaminants into the sediment begins a series of processes that may cycle contaminants back into the water column creating...

Long-Term Effects of Dredging Operations Program. Development of a Simplified Column Test for Evaluation of Thickness of Capping Material Required to Isolate Contaminated Dredged Material (2003)

Gunnison, Douglas, Brannon, James M., Sturgis, Thomas C., Smith, Issac, Jr.

A procedure using a small-scale leaching column was developed for predicting the cap thickness required to chemically seal contaminated dredged sediment from the overlying water column. Several...

Effectiveness of Capping in Isolating Contaminated Dredged Material from Biota and the Overlying Water (2003)

Brannon, James M., Hoeppel, Ronald E., Sturgis, Thomas C., Smith, Issac, Jr., Gunnison, Douglas

The effectiveness of capping in chemically and biologically isolating contaminated dredged material was investigated using large- (250 pound) and small- (22.6 pound) scale laboratory reactor units....

A Hydroponic Study of Heavy Metal Uptake by Selected Marsh Plant Species. (2002)

Lee,Charles R., Sturgis,Thomas C., Landin,Mary C.

Eight marsh plants were grown in chemically controlled hydroponic solutions containing three concentrations of heavy metals to evluate the ability of each plant species to take up and accumulate...

Establishment and Growth of Selected Freshwater and Coastal Marsh Plants in Relation to Characteristics of Dredged Sediments. (2002)

Barko,John W., Smart,Richard M., Lee,Charles R., Landin,Mary C., Sturgis,Thomas C.

An investigation of the success of establishment and the growth of marsh plants on physically and chemically different dredged sediments was conducted under semicontrolled conditions in a greenhouse....

Dredging Operations Technical Support Program. Effectiveness of Capping in Isolating Dutch Kills Sediment from Biota and the Overlying Water. (2002)

Brannon,James M., Hoeppel,Ronald E., Sturgis,Thomas C., Smith,Issac , Jr., Gunnison,Douglas

The effectiveness of capping in chemically and biologically isolating contaminated dredged material was investigated using laboratory reactor units. The ability of Buttermilk Channel cap materials to...

New Bedford Harbor Superfund Project, Acushnet River Estuary Engineering Feasibility Study of Dredging and Dredged Material Disposal Alternatives. Report 6. Laboratory Testing for Subaqueous Capping. (1998)

Sturgis, Thomas C., Gunnison, Douglas

The thickness of capping material needed to chemically sequester the polychlorinated biphenyl (PCB)-contaminated New Bedford Harbor sediment from the overlying water column and aquatic biota was...

Dredging Operations Technical Support Program: Guidance for Contracting Biological and Chemical Evaluations of Dredged Material. (1998)

Sturgis, Thomas C.

Contracting is a cost-effective method for increasing the capability of the Corps of Engineers to conduct dredged material evaluations. Test data generated by a contractor are used as an integral...

Water Quality Research Program: Studies on the Adsorption/Desorption and Microbial Mobilization of Contaminants from Sediments in Corps of Engineers Reservoir Projects. (1998)

Gunson, Douglas, Sturgis, Thomas C., Pennington, Judith C., Brannon, James M.

Laboratory studies were conducted to meet three recommendations developed in a previous technical report on sediment-water interactions and contaminants in Corps of Engineers reservoir projects...

Water Quality Studies in the Upper Yazoo Project Area, Mississippi. (1998)

Pennington, Judith C., Bunch, Barry W., Ruiz, Carlos E., Brandon, Dennis L., Sturgis, Thomas C.

Potential effects of flood control structures on water quality in the Upper Yazoo Project (UYP) area is of concern. This study was designed to provide information in the following five subject areas:...

Water Quality Studies in the Upper Watershed of Steele Bayou, Mississippi. (1998)

Ashby, Steven L., Sturgis, Thomas C., Price, Cynthia B., Brannon, James M., Pennington, Judith C.

Sediment and water quality sampling was conducted during a 1-year period at several locations in the watershed of Steele Bayou, Mississippi, to describe spatial and temporal trends. Physicochemical...

Subaqueous Cap Design: Selection of Bioturbation Profiles, Depths, and Process Rates (1998)

Clarke, Douglas G., Palermo, Michael R., Sturgis, Thomas C., Engler, Robert M.

When dredged material has been determined to contain contaminants that open-water placement would potentially cause to degrade the benthic environment, subaqueous capping with a layer of clean...

Evaluation of Manufactured Soil Using Dredged Material from New York/New Jersey Harbor Newton Creek Site. Phase 1: Greenhouse Bench-Scale Test (1998)

Sturgis, Thomas C., Lee, Charles R., Banks, Henry C., Jr., Burchell, Michael R., II, Johnson, Kervin

Manufactured soil/beneficial reuse of dredged material is a potential strategy/alternative for long-term confined disposal. The development of a manufactured topsoil product will allow the U.S. Army...

Evaluation of Toledo Harbor Dredged Material for Manufactured Soil. Phase 1: Greenhouse Bench-Scale Test (1998)

Sturgis, Thomas C., Lee, Charles R., Banks, Henry C., Jr.

Soil particles and other materials in runoff find their way to the bottom of waterways. These soil particles become sediment that eventually has to be removed from the waterways to maintain...
