Dealing with DNAPLs
Trichloroethylene (TCE) in groundwater is one of the most prevalent contamination problems at hazardous waste sites; a problem that is substantially greater if the TCE is present as dense...
Multiplicity (Available only in the Geoenvironmental Special Issue)
When it comes to tracking groundwater contaminant plumes, single completion monitoring wells are the standard choice, but they aren't the only one. After four years of trying...
Dredging Up Toxic Sediments
Lots of people like to catch their fish and eat them too, but that's a dangerous proposition when they're fishing in water polluted with highly toxic pesticides....
ETA:1999
To convert the Bergstrom Air Force Base into the Austin-Bergstrom International Airport, planners needed to overcome various technical, social, political and environmental issues. To coordinate...
Hydraulic Fracturing Advances (Available Only in Geoenvironmental Special Issue)
Removing contaminants trapped in clays and nonpermeable soils can be difficult if not impossible with traditional extraction methods. A look at four hydraulic fracturing case studies shows...
Containing Contaminants (Available Only in Geoenvironmental Special Issue)
The Environmental Protection Agency and the Department of Energy are currently in favor of containing contaminants and either remediating on site or simply capping such materials within...
Environmental Quality, Innovative Technologies, and Sustainable Economic Development
A NAFTA Perspective
This workshop proceedings assesses the current level of environmental technologies available in key media and industrial areas and their role in enhancing environmental quality in international...
Ground Water
Protection Alternatives and Strategies in the U.S.A.
Prepared by the Task Committee on Ground Water Protection of the Water Resources Engineering Division of ASCE. This report presents general hydrogeologic...
Above Par Storm-Water Management
Storm water treatment wetlands like the one on a golf course adjacent to Alabama's Mobile Bay are only marginally more expensive to construct than wet ponds, but offer distinct...
Cutting Off Water in Queens
New York's Transit Authority wanted to dig a new tunnel for a Queens subway connection, but first contractors had to wall-off the potentially contaminated groundwater nearby....
For Whom the Bugs Toil
Bioventing is soil ventilation intended to enhance the biodegradation of petroleum hydrocarbon contaminants in soils by providing a supply of oxygen. Soil microbes are capable of consuming...
Groundwater
An Endangered Resource
This proceedings,
Thai Water Mark
Thailand's economy has taken off and with new industry and population growth, water quality problems are increasing. The nation has a 20-year initiative to address these problems,...
Permanent Runoff Controls
The Center for Research in Water Resources at the University of Texas, Austin, Texas, conducted tests showing that grassy swales can remove pollutants from highway runoff. Many pollutants...
In Situ Remediation of the Geoenvironment
The progress in the development and implementation of techniques for the remediation of contaminated soil and ground water has been and continues to be rapid. These proceedings focus on...
Manufactured Gas Plants: Yesterday's Pride, Today's Liability
Manufactured gas plants were the pride of the industrialized world until cleaner, natural gas pipelines were built beginning in the 1930s. Most gas plants had closed by the 1960s, leaving...
Wonderwall
A Superfund site near Seattle was surrounded by a 2,200-ft-long soil-bentonite wall to keep contaminants from entering nearby water sources. An earlier remediation effort had failed to...
Making a Map of Public Health Hazards
Accurately deducing the long-term exposure of community members to health hazards has always been a challenge for engineers. In 1993, the town of Somers, Conn., discovered a residential...
Ground-Water Treatments Gain Ground
Ground water is the main source of the nation's public water supplies and is also used extensively for agricultural and industrial purposes. Yet our reserves are constantly...
Fracturing for In-situ Bioremediation (Available only in
A pilot-scale evaluation of an integrated pneumatic fracturing and bioremediation system demonstrated the enhanced removal of BTX from a gasoline-contaminated, low-permeability soil formation....
