Persistent Problems and Promising Solutions
This proceedings, Transportation Planning and Air Quality IV, consists of papers presented at the conference held in Lake Lanier, Georgia,...

Flight Path Precision
Air traffic delays at the four airports operated by the Port Authority of New York and New Jersey are among the most severe and costly in the nation. A study by the Port Authority proposes...

Beach Town Cleanup
The Avila Beach remediation project in California required the demolition of numerous structures and part of the beach in order to remove more than 200,000 cu yd (153,000 m�) of contaminated...

Airport Modeling and Simulation
This proceedings, Airport Modeling and Simulation contains papers presented at the conference held in Arlington, Virginia, August 17-20, 1997....

Equalizing Wet Weather Flows
Sanitary sewer overflows and combined sewer overflows can wreak havoc on communities by flooding basements, contaminating drinking water sources and recreational water bodies, and flowing...

Putting Down Roots
Phyto-covers are environmentally friendly and cost-efficient landfill barriers. Compared to traditional clay or geofabric caps, phyto-covers require less maintenance and are more friendly...

The Cover Trials
Soil erosion-control covers have been used over closed landfills for years as a means of limiting soil loss and contaminant runoff. Since 1994, the U.S. Environmental Protection Agency...

Potential Climate Change Effects on Great Lakes Hydrodynamics and Water Quality
This report provides a state-of-the-art review of the climate change effects on lake hydrodynamics and water quality. Most of the engineering cases in this book deal with the ability of...

Water, Water, Everywhere (Available in Geoenvironmental special issue only)
The discovery of extensive contamination just prior to construction of an underground library storage facility prompted engineers from the Minneapolis-based firms CNA Consulting Engineers...

Application of Linear Programming Techniques to Optimize Groundwater Withdrawals for a Pump and Treat System at Aberdeen Proving Ground, Maryland
The U.S. Army disposed chemical agents, laboratory materials, and unexploded ordnance at the O-Field landfill from before World War II until at least the 1950s. Soil, ground water, surface...

Retrofitting CSO Infrastructure in New Haven, Connecticut
(No paper) The City of New Haven Water Pollution Control Authority operates a wastewater collection and treatment system which serves over 130,000 residents in the cities of New Haven,...

Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...

Dynamic Groundwater Remediation Design with Genetic Algorithms
In groundwater remediation design it has been shown that dynamic policies, in which the pumping strategies may vary throughout the remediation period, can result in more cost-effective...

Optimization of the Aquifer Remediation Costs and Design with Pulsed Pumping
(No paper) Pump-and-treat is a common technique for the remediation of contaminated aquifers. However, slow kinetic mass transfer at sites contaminated with organic compounds may reduce...

Urban Runoff Toxicity
Toxicity is controlled by the magnitude/concentration of the contaminant produced in an exposure, the duration of the exposure, and the frequency with which exposures are repeated. When...

Cost-Effective Risk-Based In Situ Bioremediation Design
(No paper) Risk-based corrective action (RBCA) is rapidly becoming the method of choice for remediating contaminated groundwater sites, particularly for contaminants such as petroleum...

Integration of SWMM and ARCVIEW GIS for Interactive Decision Support
(No paper) This paper covers the integration of the EPA SWMM runoff model and ESRI's ArcView GIS for utilization by the City of Phoenix for decision support concerning land use changes...
