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...
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...
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...
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...
Engineered Contaminated Soils and Interaction of Soil Geomembranes
Due to liability issues, landfills are no longer considered the best method of waste disposal. Innovative, safe disposal methods for large quantities of contaminated soils and waste are...
Non-Aqueous Phase Liquids (NAPLs) in Subsurface Environment
Assessment and Remediation
The growing number of incidents of soil and groundwater contamination with non-aqueous phase liquids (NAPLs) has caught the nation unprepared. A number of challenges confronted the three...
Partnering with the Enemy
When you think of EPA and a major corporation, you probably envision them squaring off in court over a Superfund site. But these days representatives from the two groups are just as likely...
Dredging Up the Past
Disposal of contaminated dredged materials has become a national problem. The nation's ports and harbors have postponed dredging because of the cost and difficulty in finding...
Prelude to a Demolition
Building demolition conjures up images of explosives detonating or a wrecking ball haphazardly slamming into the side of a structure until it's reduced to a pile of rubble....
Cleanup Solution--Conflict Resolution
Distrust and misinformation often prevent timely resolution of ground-water contamination problems. In Toms River, N.J., engineers used a computer-generated model of the cleanup site in...
Insurance and the Environmental Engineer
The grading/excavation contractor had no problem completing the project, a routine regrading job with no visible problems or obstructions at the site, on time and on budget. Two years...

Characterization, Containment, Remediation, and Performance in Environmental Geotechnics
The impact of rapid industrialization around the globe and unsafe waste management practices have become increasingly significant within the last two decades as the disclosed number of...
Toxic Air Emissions from Wastewater Treatment Facilities
Bioremediation Comes of Age
Only five years ago engineers and scientists met with EPA officials to weigh the merits of bioremediation as a hazwaste cleanup tool. Now bioremediation has become an accepted effective...

Restoring a Stream Corridor
The Stream Restoration Project is an environmental remediation project in a residential area in the Northeast United States. The soil in the flood plain of the stream was contaminated...
The Boom in In Situ Bioremediation
In situ bioremediation was first applied in 1972 when a subsurface release of high-octane gasoline threatened the water supply of a small town in Pennsylvania. Soluble inorganic nutrients...
Mother Nature's Pump and Treat
Known under the general term of phytoremediation, using vegetation as a remedial agent has existed in its basic form for many years, mostly in applications involving waste-water treatment....
