Brownfields Boom
A brownfield is a leftover, unused industrial land parcel thought to have a prohibitively expensive clean-up required before developing. For years brownfields were battlefields for litigation...
When Toxics Meet Metal
Zero-valent iron is an emerging remediation technology that transforms chlorinated solvents to harmless substances. Engineers and researchers have been studying the process for about five...
Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...
Anchoring a Landfill Expansion
Design of a grading plan for a landfill expansion in Los Angeles County was complicated by slopes with adverse bedding planes, permitting stipulations and property setbacks. Flattening...
Monitor Well Design, Installation, and Documentation at Hazardous and/or Toxic Waste Sites
This manual provides the minimum elements for consideration in the design, installation, and documentation of monitor well placement at projects known or suspected to contain chemically...
Riddle of the Riverbed
The design of the Salt River Viaduct as part of the Red Mountain Freeway in Phoenix, Arizona, presented unique geotechnical problems. A cemented silty clay layer underneath the surface...
Boston's Home Run
The $1.3 billion Ted Williams Tunnel, the first part of Boston's Central Artery/Third Harbor Tunnel Project to be completed, has been designated the Outstanding Civil Engineering...
Back to Bacteria: A More Natural Filtration
Drinking-water treatment used to be simple: use the best source available, filter if turbidity is present and add plenty of chlorine. Typically, these are the barriers that guard against...
Scour Power
New prediction methods consistently calculate scour around bridge piers allowing engineers to better tailor pier design in rock and consolidated material. The leading cause of bridge failure...
North American Water and Environment Congress & Destructive Water
This proceedings contains papers presented at the North American Water and Environment Congress '96 of the ASCE's Environmental Engineering Division, Water Resources...
Practical Guide to Grouting of Underground Structures
This book presents a hands-on discussion of grouting fundamentals and provides a foundation for the development of practical specifications and field procedures. The author takes a practical...
Quake Proofing a Palace
A $36.5 million renovation of the California Palace of the Legion of Honor included a two-level underground expansion on a very sensitive site and the largest-ever seismic retrofit for...
Uncertainty in the Geologic Environment
from Theory to Practice
The state-of-the-art is presented with respect to analytical and design methods incorporating uncertainty in the geologic environment. Particular emphasis is placed on practical applications...
Soft Ground Improvement in Lowland and Other Environments
The presence of thick deposits of soft clay combined with the effects of ground subsidence cause problems for engineering constructions for lowland areas such as the Central Plain (Chao...
Do-Nothing Cleanups
Restoring polluted soil and ground water to pristine condition is, in some cases, neither cost-effective nor feasible. So what's the best way to close these sites with minimal...
Modeling Contaminated Sediments
Using a computer model to analyze and predict sediment transport only works when the analyst considers the model's limitations and the physical processes involved, and conducts...
Soft-Ground Subway Construction
With its 89.5 route-mile system up and running, the Washington Metropolitan Transit Authority (WMATA) is now completing the $640 million Mid-City E Route. The new line presented formidable...
Nailing A Landslide (Available only in the Geo/Environmental Special Issue)
When mud flows in California threatened to stop traffic on a freeway and erode a street from below, Caltrans worked around the clock to stabilize the slope using soil nailing and shotcrete....
Pump and Treat and Wait (Available only in the Geo/Environmental Special Issue)
Pump and treat, a common ground-water cleanup technique, is slow to clean up deep contaminated aquifers. Adaptive intermittent pumping can increase the cleanup rate�and decrease costs�by...
Asphalt-Concrete Water Barriers for Embankment Dams
Because of its simplicity in design and construction, the asphalt concrete core is rapidly becoming the water barrier of choice for embankment dams in many parts of the world. This is...
