A Storm Water Management Model for Grand Rapids, Michigan
In 1989, the City of Grand Rapids, Michigan, engaged Black & Veatch to conduct a comprehensive study of its combined sewer system with two primary objectives: (1) to relieve basement...

Evaluation of the Feasibility to Retrofit Stormwater Control Facilities to Improve Pollutant Removal Performance
This paper presents the results of an analysis that was performed to predict the efficiency of removal for suspended sediments in storm runoff under existing conditions and under several...

Reliability of Model Prediction for Pump and Treat Strategies
For the remediation of aqueous phase plumes extending over large areas simulation models are often used to predict the response of the aquifer system and the contaminant concentrations...

Methods for Designing Hydraulic Aquifer Remediation Techniques
This paper reports on recent research to develop methods for accommodating uncertainty in designing hydraulic remediation systems for contaminated aquifers. The methods rely respectively...

Statistical Analysis of Ground Water Quality Data
The Resource Conservation and Recovery Act (RCRA) requires owners and operators of hazardous waste facilities to utilize design features and control measures that prevent the release of...

The Managemet of Storm Water Runoff Associated with Industrial Activity
Section 405 of the Water Quality Act of 1987 mandates that municipal and industrial storm water discharges are point sources of water pollution and are subject to regulation under the...

Stormwater Quality Issues for Jefferson Parish
Jefferson Parish has a unique set obstacles to overcome in the operation of the drainage system. Situated in a coastal area and surrounded by water, the area has been developed through...

Source Identification and Ranking of Wet Weather Discharges in an Urban Area
A study has recently been completed to characterize the pollutant loadings to the Providence River, RI during wet weather conditions. A total of 11 land based sampling stations including...

Evaluation of Stormwater and CSO Impact on Portland's Columbia Slough
A team of consultants studied the impacts of stormwater and combined sewer overflows on an urban drainageway to determine if increased beneficial stream uses were attainable. Planning-level...
