Removal of Trichloroethylene from Clay Soil by Series-Electrokinetic Process
(American Society of Civil Engineers, 2003)The performance of a series-electrokinetic (EK) process in treating a clay soil artificially contaminated with 300 mg/kg trichloroethylene (TCE) was investigated. Constant voltage gradients of 1 or 2 V/cm to induce the ... -
Detecting Landfill Leachate Contamination Using Soil Electrical Properties
(American Society of Civil Engineers, 2003)The use of complex permittivity and electrical conductivity to detect soil contamination by landfill leachate is discussed in this paper. The electrical conductivity and complex permittivity of a natural clayey soil are ... -
Remediation of Contaminated Soils by Surfactant-Aided Soil Washing
(American Society of Civil Engineers, 2003)This paper provides reviews and updates of surfactant-aided subsurface remediation. Experimental measurements were made of various systems comprising two non-ionic surfactants, five soils of different fractional organic ... -
Zinc Uptake by Fungal Biomass Isolated from Industrial Wastewater
(American Society of Civil Engineers, 2002)In the present work, the biosorption potential of a fungal strain isolated from industrial wastewaters contaminated with zinc and other heavy metals has been investigated. Zinc biosorption studies using the fungi were ... -
Using Variances to Comply with Resource Conservation and Recovery Act Treatment Standards
(American Society of Civil Engineers, 2002)When a waste generated, treated, or disposed of at a site in the United States is classified as hazardous under the Resource Conservation and Recovery Act and is destined for land disposal, the waste manager responsible ... -
Evaluation of Reported and Measured Compositions of Household Solid Waste in Kuwait
(American Society of Civil Engineers, 2002)Nearly 2/3 of the total population in the affluent State of Kuwait include working expatriates. A significant percentage of these individuals are replaced annually by new incoming workers, often with differences in ... -
Phytostabilization of Metal Mine Tailings Using Tall Fescue
(American Society of Civil Engineers, 2002)Mined areas near the city of Galena, Kansas, provide a source of heavy metal contamination, particularly cadmium (Cd), lead (Pb), and zinc (Zn). The metals move off-site in response to erosion by wind and running water, ... -
Demolition of Gypsum Wallboard with Asbestos-Containing Mastic
(American Society of Civil Engineers, 2002)This paper reports a series of laboratory and field tests that measured the asbestos (chrysotile) fibers released during demolition of gypsum wallboard (GWB) that contained small amounts of chrysotile in the joint mastic. ... -
Comparison of Estimated and Experimentally Obtained Soil Water Distribution Coefficients
(American Society of Civil Engineers, 2002)Soil-water distribution coefficients -
Effect of Sulphur Concentration on Bioleaching of Cr(III) and Other Metals from Tannery Sludge by Indigenous Sulphur-Oxidizing Bacteria
(American Society of Civil Engineers, 2002)An investigation on the effect of elemental sulphur concentration on bioleaching of Cr(III) and other metals from tannery sludge by sludge indigenous sulphur-oxidizing bacteria was performed. Elemental sulphur concentrations ... -
Analysis of Household Hazardous Substances in Kuwait
(American Society of Civil Engineers, 2002)In the affluent State of Kuwait, every home contains hazardous substances that have the potential for posing risk to life, health, property, or the environment, if improperly consumed, stored, or disposed. A review of the ... -
Awards: New ASCE Environmental Engineering Awards
(American Society of Civil Engineers, 2002) -
Long-Term Performance Monitoring at Natural Attenuation Site
(American Society of Civil Engineers, 2002)Long-term monitoring is an integral part of the natural attenuation remediation process. It is needed to monitor the migration of a contaminated groundwater plume over time and to evaluate the extent of natural remediation ... -
Multimedia Environmental Distribution of Toxics (Mend-Tox). II: Software Implementation and Case Studies
(American Society of Civil Engineers, 2002)An integrated hybrid spatial-compartmental simulator is presented for analyzing the dynamic distribution of chemicals in the multimedia environment. Information obtained from such analysis, which includes temporal ... -
Multimedia Environmental Distribution of Toxics (Mend-Tox). I: Hybrid Compartmental-Spatial Modeling Framework
(American Society of Civil Engineers, 2002)An integrated hybrid spatial-compartmental modeling approach is presented for analyzing the dynamic distribution of chemicals in the multimedia environment. Information obtained from such analysis—which includes temporal ... -
Radionuclide Leaching from Residual Soils: Screening Study
(American Society of Civil Engineers, 2002)Four soil samples, collected from a National Priorities Listed site contaminated with uranium, thorium, and radium, were leached for two, seven, and 30 days. The nonleached soils, leached soils, and leachates were analyzed ... -
Poplar Trees for Phytostabilization of Abandoned Zinc-Lead Smelter
(American Society of Civil Engineers, 2002)Poplar trees represent one vegetation option for phytostabilization of heavy metal-contaminated sites. The objective of this study was to investigate the suitability of deep-planted hybrid poplars for phytostabilization ...
