- Guidance on the Use of Passive-Vapor-Diffusion Samplers to Detect Volatile Organic Compounds in Ground-Water-Discharge Areas, and Example Applications in New England
Polyethylene-membrane passive-vapor-diffusion samplers, or PVD samplers, have been shown to be an effective and economical reconnaissance tool for detecting and identifying volatile organic compounds (VOCs) in bottom sediments of surface-water bodies in areas of ground-water discharge. Examples of applications at nine hazardous-waste sites in New England demonstrate the utility of PVD samplers in a variety of hydrologic settings, including rivers, streams, ponds, wetlands, and coastal shorelines. Results of PVD sampling at these sites have confirmed the presence and refined the extent of VOC-contaminated ground-water-discharge areas where contaminated ground water is known, and identified areas of VOC-contaminated ground-water discharge where ground-water contamination was previously unknown. The principal VOCs detected were chlorinated and petroleum hydrocarbons. Vapor concentrations in samplers range from not detected to more than 1,000,000 parts per billion by volume. These results provided insights about contaminant distributions and ground-water-flow patterns in discharge areas, and have guided the design of focused characterization activities.

Remediation, a Summary of Contaminated Sediment Remediation Activities in the
Great Lakes Basin
A total of 33 sites in six states were listed as
past and current sediment remediation projects . These cleanups are led by
either U.S. EPA or the state environmental agency. The amount of contaminated
sediments at these sites ranged from 1,300 to 750,000 yds3. The
majority of sites chose dredging as the environmentally and economically
preferred option to remove the contaminated sediments.
- The Eriksson
System Contaminated Sediment Removal and Dewatering
Eriksson System is a proprietary method of sediment removal which reduces
the amount of sediment redistribution and water-column contamination normally
associated with other sediment removal methods. This site describes the system,
its application, and operation.
of Placement and Effectiveness of Sediment Caps
University researchers are working on an experimental program to evaluate the
fate and transport processes of polyaromatic hydrocarbons (PAH) during and
subsequent to capping. The experiments are directed toward assessing the
release of contaminants during and subsequent to cap placement and
consolidation, when significant advective transport may occur. The ultimate
goal is assessment of the long term fate of PAHs within and beneath caps.

Remediation of Contaminated Sediments, with Special Emphasis on the Great
These proceedings describe a workshop held July 17-19, 1990
in Manitowoc, WI, at which biological remediation of contaminated sediments was
of the U.S. Geological Survey (USGS) Sediment Workshop
Sediment Workshop was conceived to draw together the four Divisions of the USGS
-- Geologic, National Mapping, Water Resources, and the new Biological
Resources Division (formerly the Department of the Interior's National
Biological Service) -- to focus on the common denominator of sediment research
and monitoring, which cuts across the mission and programs of all four
Divisions. The physical and/or chemical characteristics of sediment are
recognized as fundamental to many environmental issues society faces toward
protecting, sustaining, and restoring the Nation's natural resources.
- Tiered Testing Issues for Freshwater and Marine Sediments
workshop was sponsored by the Environmental Protection Agency's Office of Water

provide an opportunity for experts in sediment toxicology and staff from EPA's
Regional and Headquarters program offices to discuss the development of
standard freshwater and marine sediment bioassay procedures.

sediments from various locales in order to test and validate theoretical
models. The project is a cooperative effort between the teams at Louisiana
State University (LSU), the Waterways Experiment Station (WES) and the
University of Minnesota (UMinn).
