 | The DoD currently has an estimated 12,000 sites that require some form of remediation related to production activities, field usage, and disposal of military unique compounds (MUCs). Chemical methods to explore types and levels of contamination, and chemical/physical and mechanical methods for cleanup of contaminated soils and sediments exist, are very costly, but do not give insight in environmental toxicity. We explore biological methods that can: (1) indicate toxicity (level ... |

|
| The objectives of this study were to provide data that can be used to predict exposure-based effects of TNT in aged soil on four endpoint organisms representing two trophic levels. These data can be used for defining criteria or reference values for environmental management and for conducting specific risk assessment. Dose-response experiments formed the basis for evaluating the toxic effects and transfer of contaminants from soil into two trophic levels, ... |

|
| In July/August 1992, the Corps of Engineers Buffalo District conducted a demonstration of equipment for dredging contaminated sediments. Several thousand cubic yards of sediment were removed from outside the Buffalo River Federal navigation channel limits using three dredge types: (1) open bucket, (2) enclosed bucket, and (3) submersible pump. The effectiveness of a silt screen deployed downstream of the dredge to reduce suspended sediment transport was also evaluated. Extensive sediment ... |

|
| Nine species of freshwater mussels collected from the Big Sunflower River, Mississippi, in 1993 were chemically analyzed for three classes of environmental contaminants. There was a proposal to harvest these animals for their shells and to use the tissues for animal feed. Mussels were collected from eight sites, from River Miles 34.5 to 150 (near Cleveland, MS). The tissues were analyzed for metals, pesticides, and polychlorinated biphenyls (PCBs). Metals, including ... |

|
| This report describes testing and evaluation performed by the Environmental Laboratory of the U.S. Army Engineer Waterways Experiment Station (WES) on sediment from the Santa Fe Channel of Richmond Harbor, California. Test protocols from the Corps' Management Strategy for Disposal of Dredged Material were used in the present evaluation to determine the potential for migration of contaminants into the effluent, surface runoff, and leachates at an undetermined upland disposal site. ... |

| Navigable waterways of the United States have a vital role in the Nation's economic growth. The US Army Corps of Engineers is responsible for the dredging and disposal of large volumes of sediment each year. Dredging is a process by which sediments are removed from the bottom of streams, rivers, lakes, and coastal waters, transported via ship, barge, or pipeline, and discharged to land or water. The presence of contamination ... |

|
| Current guidance on storage of sediments for bioassay/bioaccumulation tests requires that samples be held at 4 C and used within 2 weeks of collection. The objective of this study was to determine the effects of sediment storage for 40 weeks on sediment toxicity, bioaccumulation potential, and chemical analyses. Toxicity and bioaccumulation tests were conducted five times during 40 weeks of storage. Chemical analyses were performed three times during this period. ... |

|
 | This concerns use of dredged material containment areas (DMCA) for aquaculture, specifically for production of a crop intended for human consumption. New DMCA's used only periodically for dredged material disposal could be managed to produce valuable crops. Previous studies conducted by the Corps of Engineers, including one where shrimp raised at a DMCA, and others relating to the effects of sediment contaminants on aquatic organisms, are reviewed. The literature indicated ... |

|
| This study describes culture techniques and results of toxicant bioassays using the California mysid, Acanthomysis sculpta, the polychaete, Neanthes arenaceodentata, and the gulf cost mysid, Mysidopsis bahia. The mysids were tested with three toxicants: dodecyl sodium sulfate (DSS), also known as sodium laurel sulfate; mercury (Hg); and polychlorinated biphenyls (PCB). The LC50 value at 72 hr for DSS showed the California mysid (0.96 ppm) more sensitive to this standard toxicant ... |

|
| Biological assessment studies of the standard elutriate have been conducted using selected species of algae, bacteria, and protozoans as representative test organisms. Algal bioassays have proven useful in providing information about the biologically available nutrients released from the sediments. Growth was determined by measuring the maximum number of cells per milliliter of treatment. The treatments included 100-percent disposal site water, 100-percent elutriate, and various combinations of elutriate and disposal site ... |
