RISEvaluation of EPA's Hazard Ranking System
Publisher: American Society of Civil Engineers
Abstract: This paper analyzes and evaluates the EPA's hazard ranking system for uncontrolled hazardous waste sites. Two hypothetical sites were developed from several actual case studies for use in the analysis. Sensitivity analyses ...
Artificial Neural Networks for Forecasting Watershed Runoff and Stream Flows
Publisher: American Society of Civil Engineers
Abstract: This research demonstrates an application of artificial neural networks (ANN) for watershed-runoff and stream-flow forecasts. A watershed runoff prediction model was developed to predict stormwater runoff at a gauged ...
Systematic Evaluation of Pollutant Removal by Urban Wet Detention Ponds
Publisher: American Society of Civil Engineers
Abstract: Three urban wet detention ponds in the Piedmont of North Carolina were monitored to investigate long-term pollutant removal as a function of surface to area ratios. Eleven storm events were monitored over a sampling period ...
Reaction Kinetics of Immobilized-Cell Denitrification. I: Background and Model Development
Publisher: American Society of Civil Engineers
Abstract: A simplified, quasi-steady-state model has been formulated for groundwater denitrification using immobilized cells. The model takes into account the diffusion-limited penetration of nitrate and nitrite into the immobilized-cell ...
Reaction Kinetics of Immobilized-Cell Denitrification. II: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were conducted to characterize the performance of an immobilized-cell denitrification process treating nitrate-contaminated groundwater and to provide supporting data for the validation of a quasi-steady ...
Closure to “Systematic Evaluation of Pollutant Removal by Urban Wet Detention Ponds” by Jy S. Wu, Robert E. Holman, and John R. Dorney

Fee Credits as an Economic Incentive for Green Infrastructure Retrofits in Stormwater-Impaired Urban Watersheds
Publisher: ASCE
Abstract: Low participation rates in existing US stormwater utility fee credit programs indicate that the benefits attributed to credits are not being realized, most notably, the financial incentive for private property owners to ...
Characterization and Pollutant Loading Estimation for Highway Runoff
Publisher: American Society of Civil Engineers
Abstract: Three highway segments typical of urban, semiurban, and rural settings in the Piedmont region of North Carolina were monitored to characterize the respective runoff constituent concentrations and pollutant discharge or ...
Columnar Biological Treatability of AOC under Oligotrophic Conditions
Publisher: American Society of Civil Engineers
Abstract: The biological treatability of assimilable organic carbon (AOC) in drinking water was investigated under oligotrophic conditions. AOC of the simulated feed was provided with model compounds such as glucose, acetate, or ...
Energy-Water Nexus: Potential Energy Savings and Implications for Sustainable Integrated Water Management in Urban Areas from Rainwater Harvesting and Gray-Water Reuse
Publisher: American Society of Civil Engineers
Abstract: Saving water saves energy. Consequently, implementing integrated water management (IWM) measures that reduce potable water consumption, stormwater runoff, and wastewater generation can potentially translate into significant ...
