Light at the End of the Tunnel
As part of a comprehensive program to control combined sewer overflows in Richmond, Virginia, engineers designed a deep tunnel 5,900 feet long to store the polluted water during severe...

Fundamentally Sound
Through careful coordination of remediation work that will include the dredging of contaminated sediment and the control of storm water, a busy Seattle shipyard is charting a course for...

Liquid Assets
Educational Facilities and the fountains of a new plaza are making good use of water from a system that is remediating contaminated groundwater in Wichita, Kansas....

Integrated Water Management for the 21st Century: Problems and Solutions
Most of the projected global population increases will take place in third world countries that already suffer from water, food, and health problems. Increasingly, the various water uses...

An Alternative Approach
An innovative foundation system at a Virginia power plant relies on columns constructed via jet grouting to support elevated units that reduce pollution. The approach required less drilling,...

Assessing Long-Term Pollutant Concentration Trends in Urban Runoff for TMDL Planning and Regulatory Assessment
Loads of some pollutants in many urban watersheds include a substantial component originating with non-point sources and stormwater runoff. TMDL planning includes estimating those loads,...

Practical Groundwater and Conjunctive Water Optimization
The Simulation/Optimization MOdeling System (SOMOS) makes it easy to do groundwater optimization modeling for a variety of scales and situations. The SOMOA module uses analytical equations,...

Thermal Cyclone Washing for Remediation of Petroleum Contaminated Soils
Thermal Cyclone Washing (TCW) is a soil remediation technology developed and tested at the University of Alabama in Huntsville. TCW is a combination of thermal, chemical, and physical...

Effectiveness of a BioInfiltration BMP
This paper presents results from a project to construct and study a BioInfiltration Traffic Island on the grounds of Villanova University. The projects goals were to 1. To create a bioretention...

Panel Discussion on Stormwater Issues in Pennsylvania
The management of stormwater in Pennsylvania has radically changed over the last several years due to the concern of the citizens of the Commonwealth, and the advent of NPDES Phase II....

Application of the NRC Framework for Evaluation of Remedial Actions at a PCB Contaminated Sediment Site
The National Research Council recently proposed that the framework of the Presidents/Congressional Commission on Risk Assessment and Risk Management be applied to the selection and implementation...

The Cyanic Threat
In the past terrorists have attempted to contaminate drinking water supplies in the United States with cyanide - one of the most lethal poisons known to man. So far they have been unsuccessful....

Storm-Water Strategy
Water pollution laws are certainly nothing new, but increased public scrutiny, beach closures, and media coverage—particularly in Orange County, California—have placed new pressures on...

Consolidated Effort
Engineers remedied a landfill polluted with polychlorinated biphenyls by removing the most contaminated detritus and consolidating the rest under a multilayered, impermeable cap....

Penn State's Graduate Option in Watershed Stewardship
A Graduate Option in Watershed Stewardship has been created at Penn State with the objective of educating water resources students to implement team-oriented, interdisciplinary problem...

Shape of Storm Pollutograph from the Four Different Rural Watersheds
(Abstract only) Just as a hydrograph describes the flow rate of water for a storm event, a pollutograph shows the rate at which pollutants dissolved or suspended in the runoff are transported....

Implementation of the Phase II Stormwater NPDES Permits
In the 1987 amendments to the Clean Water Act, Congress directed the United States Environmental Protection Agency (EPA) to establish a permitting framework under the National Pollutant...
