Enhanced Soil Flushing for Simultaneous Removal of PAHs and Heavy Metals from Industrial Contaminated Soil
(American Society of Civil Engineers, 2011)Polycyclic aromatic hydrocarbons (PAHs) and heavy metals are environmental concerns and must be removed to acceptable levels. This paper evaluates different flushing agents to enhance the remediation of soil contaminated ... -
Sensitivity Analysis of Risk Assessment at a Petroleum-Hydrocarbon Contaminated Site
(American Society of Civil Engineers, 2011)In this study, sensitivity analysis was performed to evaluate the effectiveness of input parameters on the calculated risks at a petroleum-hydrocarbon contaminated site. Under a risk-based corrective action (RBCA) approach, ... -
Microscopic Modeling of Air Migration during Air Sparging
(American Society of Civil Engineers, 2011)Air sparging is an emerging soil remediation method to decontaminate saturated granular soils and groundwater with volatile organic compounds (VOCs). The efficiency of an in situ sparging system is controlled by the extent ... -
Influence of Soil–Multiple Contaminant Retention Parameters on Contaminant Fate Prediction
(American Society of Civil Engineers, 2011)Determination of contaminant interaction with soil is essential for predicting its fate in geoenvironments. Several studies have appraised contaminant fate prediction based on the results of single contaminant-soil ... -
Sorption of Neutral Organic Compounds in Mixtures to Mineral Surfaces and Humic Acid-Mineral Complexes
(American Society of Civil Engineers, 2011)The sorption of 12 neutral organic compounds (NOCs) contained in mixtures to both hydrophilic mineral surfaces [uncoated, iron (hydr)oxide-coated, and aluminum (hydr)oxide-coated sands] and humic acid-mineral complexes ... -
Prediction of Arsenic Removal by Electrocoagulation: Model Development by Factorial Design
(American Society of Civil Engineers, 2011)Model was developed by two-level five-factor full-factorial designed-experiment to predict arsenic removal from contaminated water by electrocoagulation. Five factors, namely arsenic concentration (As), solution volume -
Quality of Runoff Leachate Collected from Biosolids and Dairy-Manure Compost-Amended Topsoils
(American Society of Civil Engineers, 2011)Compost amendment of pavement shoulder subgrades was attempted to mitigate shrinkage cracking, which otherwise would result in severe distress to adjacent pavement infrastructure systems. Two types of composts, biosolids ... -
