Development of an Experimental Watershed for Testing Nonpoint Source Pollution from Urban Runoff
The U.S. Environmental Protection Agency (EPA) National Pollution Discharge Elimination System (NPDES) stormwater regulation program prohibits non-storm water discharges into entering...
Urban Runoff Based on Land Use and Particle Size
As point sources have achieved pollution compliance, the focus of pollution abatement has shifted to nonpoint sources. New Federal regulations require wet-weather monitoring of drainage...
Non-Point Pollution Loadings and their Impacts on Tennessee Valley Reservoirs
This is a three-year study which began in March 1992. The project has focused on inflow streams entering storage projects including Douglas, Cherokee, South Holston, Watauga, Norris, Chatuge,...
Non-Point Source Pollution Reduction
The paper reports on the results of a study to determine the effectiveness of the best management practices (BMPs) for use in the Tampa Bay Watershed. The study aims to determine the efficiency,...
Deicing Denver
Glycol-based deicing fluids are an essential part of winter operations at most airports. While these chemicals help ensure safe and timely aircraft operations, stormwater runoff contaminated...
Estuarine and Coastal Modeling
This volume contains the proceedings of the 3rd International Conference on Estuarine and Coastal Modeling held in Oak Brook, Illinois, September 8-10, 1993. The conference included sessions...

Constructing Around Contamination
When soil and ground water contamination are found at a construction site, completing the project on time and within budget is always a challenge. Typical problems include constraints...
Computer-Aided Cleanup
In late 1992, the remedial investigation of Operable Unit 2 at the Department of Energy's Fernald Superfund site in Ohio was in trouble. Despite years of effort-including...

Computer Control of CSOs
Like many older cities, St. Louis has a combined sewer system and is faced with the difficulties of dealing with combined sewer overflows (CSOs). The Metropolitan St. Louis Sewer District...
Dredging '94
During the past decade, the discipline of dredging has been challenged in the areas of economics, the environment, and management of dredging projects. Dredging has kept pace with its...
Integration of a Traffic Noise Model and AutoCAD
TrafficNoiseCAD represents a new approach to noise analysis and barrier design by integrating file creation for the FHWA STAMINA 2.0 noise prediction program with interactive graphical...
A Natural Cleanup
For almost 30 years, nonvolatile petroleum hydrocarbons from used motor oil, diesel, gasoline and other automotive fluids had been released to an oil sum at a truck-maintenance facility...
Data Validation Practices and Risk Assessment
The accuracy of environmental site assessments depends on the validity of the data used to make them, but all too often, the people who judge the quality of the data have little idea of...
IVHS: The Invisible Revolution
Federal funding for intelligent vehicle highway systems has increased a hundredfold since 1989, from $2 million to almost $200 million. Transportation planners are looking increasingly...
Predicting Pollution
For urban areas struggling to meet the requirements of the 1990 Clean Air Act as well as state air-quality mandates, accurate forecasting of mobile emissions is critical to evaluating...
Sensitivity Analyses for Total-System Performance Assessment
As a follow-on to Sandia's 1991 preliminary total-system performance assessment of the Yuc1ca Mountain site, this paper presents results of some sensitivity analyses that were done using...
Radionuclide Migration to the Aquifer Through the Porous Medium
Time dependent doses of radionuclides from a waste container to the aquifer through porous medium are analyzed for (1) congruently released transuranic elements such as Np-237 and (2)...
