Application of the NRC Framework for Evaluation of Remedial Actions at a PCB Contaminated Sediment Site
The National Research Council recently proposed that the framework of the Presidents/Congressional Commission on Risk Assessment and Risk Management be applied to the selection and implementation...

Consolidated Effort
Engineers remedied a landfill polluted with polychlorinated biphenyls by removing the most contaminated detritus and consolidating the rest under a multilayered, impermeable cap....

Effects of Estuarine Habitat Quality on Juvenile Salmon: I. Chemical Contaminant Exposure and II. Altered Growth and Immune Function
Some urban estuaries on the west coast of the US are important habitats for several species of juvenile salmon and receive multiple stresses from human activities. Because these estuaries...

The NS&T National Benthic Surveillance Project: Contaminants in Fish Tissues
The National Benthic Surveillance Project, part of NOAA's National Status and Trends (NS&T) Program, has been regularly measuring more than 70 contaminants in liver tissue of selected...

Use of Floodplain PCB Concentrations to Calibrate a River Hydraulics Model
A river floodplain was found to contain measurable quantities of polychlorinated biphenyls (PCBs), presumably deposited during historic flood events. A hydraulic model (HEC-2) was used...

Stabilization and Fixation Using Soil Mixing

Fate of PCBs in Municipal-Sludge Amended Soil
This paper presents the preliminary results of a five-year field study of the fate of PCBs in soil that has been amended with municipal sewage sludge. A first-order model describes the...

Volatilization of PCBs From the Great Lakes
The potential volatilization of polychlorobiphenyls (PCBs) and other semi-volatile organic chemicals (SOCs) from Lake Superior and Green Bay, Lake Michigan, is being investigated. The...

Long-Term Fate of PCB Contamination in the New Bedford Harbor, Massachusetts, System
The transport and fate of polychlorinated biphenyls (PCBs) at the New Bedford Harbor Superfund site is modeled using a three-dimensional hydrodynamics and sediment-contaminant transport...

Development of a Dredging Elutriate Test for Predicting Release of Contaminant at the Point of Dredging

The Dredging Dilemma
Disposal of dredge materials is becoming a national environmental problem. Disposal sites on land are becoming extremely scarce and environmental objections growing. There are also objections...
