Effect of Air Pollution on Atmospheric Corrosion of Engineering Metals
(American Society of Civil Engineers, 2004)Atmospheric corrosion is probably the most common form of corrosion and is defined as the corrosion or degradation of material exposed to air and its pollutants. This study essentially deals with atmospheric corrosion to ... -
Selection of the Appropriate Aggregation Function for Calculating Leachate Pollution Index
(American Society of Civil Engineers, 2004)A technique to quantify the leachate pollution potential of landfills on a comparative scale using an index known as the Leachate Pollution Index (LPI) has been developed and reported elsewhere. The LPI is a quantitative ... -
Strategies to Mitigate Salt Runoff from Salt Storage and Salt Truck Maintenance Facilities
(American Society of Civil Engineers, 2004)Mitigating salt runoff at salt storage and salt truck maintenance facilities has become a concern for many state departments of transportation (DOTs), since their storm water discharge is found to pollute the environment. ... -
Cleaner Production for Sustainable Industrial Development: Concept and Applications
(American Society of Civil Engineers, 2004)In the 21st century, no business can successfully operate in an economic and social vacuum. Enterprises can achieve enduring success only by meeting the needs and the expectations of all their key constituents: customers, ... -
Hazardous Waste and Solid Waste Infrastructure
(American Society of Civil Engineers, 2004)Proper waste management is essential to protect human health, ecosystems, and economic prosperity. Between 2001 and 2003, the St. Louis Section of the American Society of Civil Engineers evaluated the environmental ... -
Long-Term Migration of Light Nonaqueous-Phase Liquids in Two Unsaturated Soils: Clayey Silt and Fine Sand
(American Society of Civil Engineers, 2004)Centrifuge modeling of the long-term migration of light nonaqueous-phase liquids (LNAPLs) in unsaturated soils has been accomplished at a gravitational acceleration of -
Applicability of Caliche (Gatch) as Liner/Cover in Arid Climate Landfills: Laboratory and Field Pad Testing of Permeability
(American Society of Civil Engineers, 2004)Modernization of municipal solid waste (MSW) landfills needs basic environment protection furnished by base liner and cover systems. In an effort to help developed arid countries build safe MSW sites that are environmentally ... -
Analytical Contaminant Transport Analysis System (<i>ACTS</i>)—Multimedia Environmental Fate and Transport
(American Society of Civil Engineers, 2004)The analytical contaminant transport analysis system ( -
Leachate Dispersion in Aquifers under Disposal Facilities
(American Society of Civil Engineers, 2004)Contaminated dredged material is often placed in confined disposal facilities (CDFs) designed and operated to control environmental impacts of the disposed sediment. A CDF is a diked enclosure having structures that retain ... -
Production of Hydroxyl Radicals from the Decomposition of Hydrogen Peroxide Catalyzed by Various Iron Oxides at pH 7
(American Society of Civil Engineers, 2004)The hydroxyl radical -
Public Health Risk of Arsenic Contamination at a Public Park in Deer Lodge, Montana
(American Society of Civil Engineers, 2004)This paper reports an effort by the Agency for Toxic Substances and Disease Registry (ATSDR) to identify whether the arsenic soil concentrations in a public park in Montana were a health concern for park users. Concern was ... -
Evaluation of Different Slurry Materials for Containment Wall Construction at a Dense Nonaqueous Phase Liquid-Contaminated Site
(American Society of Civil Engineers, 2004)A water-bearing granular soil layer within the subsurface of a former manufactured gas plant (MGP) site is impacted with tarry dense nonaqueous phase liquid (DNAPL). A containment wall constructed with the vibrated beam ... -
Interpretation of Soil Properties in Kuan-Tu Wetlands, Taiwan
(American Society of Civil Engineers, 2004)This work investigated soil samples collected from the Kuan-Tu wetlands, Taiwan. Factor analysis was performed to explain the impact of various environmental factors on this coastal wetland located in suburban Taipei. The ... -
Flow and Solute Transport in Strongly Heterogeneous Porous Media
(American Society of Civil Engineers, 2004)The stochastic analysis of flow and solute transport provides the required probabilistic information for the risk assessment of hazard and radioactive waste management. Only low-order approximations of the velocity covariance ... -
Extraction of Copper from a Low-Grade Ore by Rhamnolipids
(American Society of Civil Engineers, 2004)Mining residues, in general and metal ores, in particular, contain heavy metals within the rock. These heavy metals, including copper (Cu) for which there is an increasing demand around the world, are very harmful to humans ... -
Application of Health Risk Assessment to Derive Cleanup Levels at a Fuel-Oil Spill Site
(American Society of Civil Engineers, 2004)Risk-based corrective action (RBCA) has been becoming an accepted approach for the remediation of contaminated sites. This paper described the application of four different risk assessment approaches, including the North ... -
Enhancing Attenuation of Petroleum Pollutants by Modifying Natural Soil with Surfactants
(American Society of Civil Engineers, 2004)Large oil fields are distributed within the loess plateau of northwest China, where severe soil contamination by petroleum hydrocarbons has been found in several locations. A prevention measure is to modify the topsoils ... -
Spatial Heterogeneity of Microbial and Geochemical Parameters in Gasoline Contaminated Aquifers
