In Situ Treatment of VOCs by Recirculation Technologies
Confronted with contaminated land from the world wars and the postwar industrialization period, German researchers and practicing professionals have worked to develop processes for effective...
Arsenic Removal Via Softening
The removal of arsenic during softening was investigated using synthetic solutions. Arsenic removal is facilitated by formation of a variety of solids including Mg(OH)2,...
Environmental Effects of Flooding at a USCG Base
In July of 1993, the U.S. Coast Guard (USCG) Base St. Louis facility was flooded. As the flood waters receded and cleanup efforts were initiated, a number of environmental issues had to...
Transport Process of Surface Liquid Spills
A mathematical model simulating the scenarios of surface liquid spills is presented in this paper. This model describes the advance front and recession curves of surface spills based on...
A model to describe the fate of agricultural pollutants
The distributed parameter hydrological model CEQUEAU is coupled to nitrogen and pesticide sub-models to study agricultural non-point pollution at the watershed level. This developing tool...
Predictability and Sensitivity of Groundwater Transport Models
The uncertainty associated with predictions made by solute transport models in groundwater environments must be carefully evaluated to address spatial and time variability as well as data...
Monitoring Petroleum Contamination in an Aquifer
An experimental study of the behavior of petroleum in an aquifer with static and changing water depths were studied. The experimental apparatus consisted of plexiglass tanks filled with...
Groundwater Remediation at a Superfund Site
Soil and groundwater contamination at the Montana Post & Pole site in Butte, Montana, one of the nation's oldest Superfund sites, has developed into one of the most significant...
Fate/Transport Modeling and Remediation of Contaminated Plume at Vance Airforce Base
Air Training Command (ATC) at Vance Air Force Base (VAFB) is responsible for implementing the Installation Restoration Program (IRP) according to the Comprehensive Environmental Response,...
Genetic Algorithms in Groundwater Management
The aim of this paper is to examine applicability of genetic algorithms in groundwater planning and management. A brief description of genetic algorithms and the associated advantages...
Threshold Precipitation Events and Groundwater Recharge
Data from two study sites on the Nevada Test Site, Nevada are used with precipitation data from other long-term precipitation gages to identify the frequency of precipitation events that...
Estimation of Field Site Flow Parameters
The paper reports on the use of Kriging to obtain estimates of hydraulic conductivity underneath a rapid infiltration site. The parameters obtained were used in a two-dimensional groundwater...
Groundwater Development and Related Issues
Optimum development and management of ground water resources requires consideration of all elements of the groundwater system and their inter-relations with total hydrologic cycle along...
Movement of Colloids Under Hydraulic Gradients
A model was developed for analyzing the movement of colloidal clay particles in laboratory soil columns. The physical mechanisms of detachment of particles from the soil matrix, their...
Development of Transport Model for Groundwater Planning and Management in Taipei Basin
The objective of this paper is to develop a groundwater model for contaminant transport simulation. The transport model, in conjunction with the previously developed flow model, is used...
1993 Ground-Water Flooding in the Havana Area
The Havana area in Mason County, west-central Illinois, experienced nearly continuous rises in the water table beginning in the fall of 1992 which created lakes in depressed areas. Water...

Constructing Around Contamination
When soil and ground water contamination are found at a construction site, completing the project on time and within budget is always a challenge. Typical problems include constraints...
Computer-Aided Cleanup
In late 1992, the remedial investigation of Operable Unit 2 at the Department of Energy's Fernald Superfund site in Ohio was in trouble. Despite years of effort-including...
A Natural Cleanup
For almost 30 years, nonvolatile petroleum hydrocarbons from used motor oil, diesel, gasoline and other automotive fluids had been released to an oil sum at a truck-maintenance facility...
