Toxicology and Chemistry of Metals in Urban Runoff
Water quality characteristics such as inorganic and organic ligands, pH, and water hardness will reduce the toxicity of metals through different chemical or physiological mechanisms. Increases...
Disciplinary Integration: The Solution
The objective of this paper is to encourage a careful review of the interactions between engineers and bioenvironmental scientists (biologists, ecologists, and ecotoxicologists) as they...
Review of Data Needs and Collection Technology
The quality - or pollutional effect - of urban runoff has not attained a societal level of importance sufficient to support understanding it, much less controlling it. The paper reviews...
Sources of Urban Pollutants?Do we Know Enough?
The non-USGS data from the NURP program are summarized in terms of their availability and adequacy for decision making and modeling. Results of selected projects are reviewed and related...
Estimation of Urban Storm-Runoff Loads
The United States was divided into three regions, on the basis of mean annual rainfall, to decrease the variability in storm-runoff constituent loads and to improve regression relations...
Urban Runoff and Water Quality Criteria
The significance of water quality impacts from urban runoff could be judged on the basis of existing water quality criteria developed to control continuous point source discharges. Wet-weather...
Pollution Sources and Potential Impacts?Next Steps
The paper presents the propositions that there is much to learn about what determines the magnitude and variability of pollutant loads in urban runoff; and with the exception of nutrient...
Potential Impacts on Receiving Waters
As a discrete source of water-borne pollutants that are discharged to receiving waters, urban stormwater runoff can be and has been in specific instances a source of water quality problems....
Assessing Biological Effects of Contaminants In Situ
This paper presents a monitoring strategy for assessing the effects of anthropogenic contaminants on aquatic organisms. This strategy takes advantage of our increased understanding of...
Impacts of Urban Runoff on Estuarine Ecosystems
This paper first attempts to characterize the types of pollutants which could be expected to enter an estuary from urban runoff. Then, based on existing knowledge of the impacts of various...
Urban Runoff Impacts on Receiving Waters
Urban stormwater runoff contaminants affect the principal receiving water uses of: (1) public water supply, (2) recreation, (3) protection of aquatic life forms, (4) agricultural and industrial...
EPA's Perspective of Urban Nonpoint Sources
The overall goal of the Nationwide Urban Runoff Program (NURP) was to develop information that would help provide local decision makers, States, EPA, and other interested parties with...
Bellevue's Urban Storm Water Permit and Program
The Bellevue Storm Water Management Utility has been in operation for over ten years. At its initiation, flooding and erosion control were its main mission. Today with increasing focus...
Stormwater Management in Orlando, Florida
Metropolitan Orlando, Florida contains 82 lakes and approximately 200 drainage wells which serve as ultimate outfall for stormwater runoff. The quality of the surface receiving waters...
Stormwater Regulatory Program in Florida
The Florida Department of Environmental Regulation developed a regulatory program for the control of nonpoint sources. The Stormwater Rule established a performance standard for the treatment...
Commentary on Papers on Institutional Issues
The objective of this review is to comment on the four papers presented during this session and to highlight institutional issues about which the author is particularly concerned. Institutional...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Runoff Controls in Wisconsin's Priority Watersheds
The Wisconsin nonpoint source program is becoming more heavily involved in urban runoff controls. About 3 million of state cost sharing money has already been allocated to controlling...
Effectiveness of Extended Detention Ponds
Field and laboratory studies of the performance of detention facilities for the removal of selected pollutants from urban stormwater were conducted. The laboratory studies consisted of...
Design and Effectiveness of Urban Retention Basins
Retention basins are recommended by practicing engineers and regulatory agencies for stormwater management in new land developments. They may require considerable space which limits their...
