Using Climate Model Decadal Predictions and Statistical Extrapolations of Location-Specific Near-Term Temperature and Precipitation for Infrastructure Engineering
Publisher: ASCE
Abstract: Location-specific, near-term (≤10 years) temperature and precipitation conditions are informative and important in many infrastructure engineering activities. Two alternative approaches for obtaining near-term future climate ...
Microcosm Approach to Study Transport of Polychlorinated Biphenyls in Sediment
Publisher: American Society of Civil Engineers
Abstract: The transport of polychlorinated biphenyls (PCBs) in sediment is difficult to study in the laboratory due to their low solubility and strong tendency to sorb to sediment and experimental equipment. A small-scale laboratory ...
Adsorption of Inorganic Pollutants in Aquatic Systems
Publisher: American Society of Civil Engineers
Abstract: Adsorption often dictates the fate of trace inorganic pollutants in aquatic systems. In contrast to the nonspecific sorption mechanism proposed for hydrophobic organic compounds, adsorption of inorganic solutes is viewed ...
Evaluation of Uncertainty in a Site-Specific Risk Assessment
Publisher: American Society of Civil Engineers
Abstract: An evaluation was performed of the uncertainty in predicted carcinogenic risk resulting from uncertainty in site properties and fate and transport predictions for a simple contaminated soil site. SoilRisk, a risk model for ...
Impact of Tertiary Treatment Processes on the Effectiveness of Chloramination for Biological Growth Control in Recirculating Cooling Systems Using Treated Municipal Wastewater
Publisher: American Society of Civil Engineers
Abstract: Adequate biocide addition is the key to control biological growth-related problems in recirculating cooling systems of thermoelectric power plants. The use of monochloramine (MCA) as the primary biocide is as effective as ...
Mechanisms of Neutralization of Bauxite Residue by Carbon Dioxide
Publisher: American Society of Civil Engineers
Abstract: Bauxite residue (red mud), an alkaline slurry from alumina refining, is produced in large volumes and disposed of in large surface impoundments. The objectives of this study were to measure the extent of neutralization of ...
Risk Variability from Uniform Soil Remediation Goals for PCBs
Publisher: American Society of Civil Engineers
Abstract: A methodology for evaluating the variability of risk resulting from the use of uniform, concentration‐based soil‐quality criteria is developed and applied to polychlorinated‐biphenyl‐(PCB‐) contaminated soil as an example. ...
SoilRisk: Risk Assessment Model for Organic Contaminants in Soil
Publisher: American Society of Civil Engineers
Abstract: This paper describes in detail a new integrated risk model, SoilRisk, for low-levels of organic pollutants in soil. An analytical model of the fate and transport of organics in unsaturated soil is used where chemical losses ...
