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...
Grouting Pains (Available in Geoenvironmental Engineering Special Issue)
The article focuses on a new grouting technique for filling holes drilled during site investigation. The holes are grouted as the drill is withdrawn from the hole, instead of filled later....
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...

Dormant Season Alfalfa Water Balance on the NIIP
Non-growing season water balance parameters were measured for alfalfa under high-elevation desert conditions of the Navajo Indian Irrigation Project in northwest New Mexico. The lysimeters...
Discharge Measurements and Predictions in Wetlands
Existing procedures used to estimate discharge in wetland environments are evaluated. Suggestions are made for possible improved methodologies based on field investigation. Suggestions...
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...
Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...
Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...
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...
The Integration of Receiving Water Impacts in the Evaluation Process of Alternative Designs for CSO Abatement in Providence, RI
The Providence, Rhode Island sewer system is undergoing a combined sewer overflow abatement program. One measure of the program's effectiveness is the reduction of water quality...
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...
