Pump-and-Treat Rescue
The pump-and-treat method of remediation has been regarded for years as unsuccessful and untrustworthy. But a recent project in Chicago showed that in conjunction with horizontal wells...
Nothing Wasted
Anoxic gas flotation (AGF), a patented system for anaerobic digestion of organic slurry waste, can recover as much as 85% of the phosphorus and 23% of the nitrogen in slurry waste, while...
Putting Wetlands to Work
Wetlands, whether natural or engineered, have enormous potential to clean up wastewater, but in the past, the public called on civil engineers to drain wetlands en masse as a public benefit....
Oil in the Soil
An oil well blowout in northern Italy contaminated about 1,500 ha of agricultural land primarily used to cultivate rice. The cleanup team decided to use bioremediation techniques because...
Everything Old Is New Again
Chicago's elevated Green Line, which connects Chicago's south and west sides with the downtown loop, has recently gone through an overhaul, getting new tracks,...
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...
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...

Simulating Evapotranspiration on Semi-Arid Rangelands
Detailed simulations of the surface energy balance using the Simultaneous Heat and Water (SHAW) model were compared with measurements collected at the Reynolds Creek Experimental Watershed...
Hazardous Soil Remediation: A Cooperative Effort between Industry and Government
E. I. du Pont de Nemours and Company's Antioch Works (Dupont) is on the San Joaquin River 30 miles east of San Francisco, California. For about 25 years, ending in 1981, Dupont...
Aquifer Transmissivity Computations Based on Data from Pump-and-Treat Facilities
Contamination from petroleum hydrocarbons spilled from USTs is a concern in urban areas that depend on shallow unconfined aquifers for their water supply. Studies on the transmissivity...
Reductive Pyrolysis for the Destruction of Chloromethane: A Reaction Pathway Model Based on Thermodynamic and Thermokinetic Considerations
Among various thermal technologies available for the destruction chlorinated hydrocarbons, incineration, catalytic hydrogenation, and pyrolysis are important. Pyrolysis employed under...
Protecting Drinking Water: Rapid Detection of Human Fecal Contamination, Injured, and Non-Culturable Pathogenic Microbes in Water Systems
The rapid, potentially-automatable extraction of filter retentates has allowed quantitative detection of the unique biomarker for human fecal contamination, coprostanol, and the signature...
Direct Sizing of Small Stormwater Pump Stations
Pump stations are components of stormwater drainage systems that remove collected storm runoff from locations where drainage by gravity is not feasible. Usually pump stations will operate...
Biodegradation Modeling of a Closed Landfill Site
The two-dimensional model, BIOPLUME II, was applied to the closed Becker County Landfill at Detroit township, Minnesota, to study the transport of hydrocarbons occurring at the site. The...
Adhesion Kinetics of Fuel Oil #6 and Oil-in-Water Emulsions on Marine Sediments under Turbulent Mixing Conditions
Oil spilled in the marine environment is subject to a great variety of physical, chemical and biological processes, which determine its ultimate fate in the aquatic environment. Many of...
