Review of Stabilization of Clays and Expansive Soils in Pavements and Lightly Loaded Structures�History, Practice, and Future
Expansive clay soils�those that change significantly in volume with changes in water content�are the cause of distortions to structures that cost taxpayers several billion dollars annually...

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,...

Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...

Fate of TCE in Phytoremediation Systems
The phytoremediation of trichloroethylene (TCE) and other volatile organic compounds (VOCs) has been developed from a mere concept to full applications over the past decade. However, the...

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...

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...

Preserving Pisa's Treasure
Pisa's bell tower, a prime example of Romanesque architecture, would be renowned even if it did not lean. Construction of the tower began in 1173 and was not completed until...

Deep Freeze
In engineering, overcoming a failure can sometimes be more instructive than completing a project with unqualified success. Such was the case with the collapse and repair of a force main...

Larger Foraminifers as Contributors to Carbonate Beach Sands
Larger foraminifers are locally significant contributors to tropical carbonate sediments, particularly in the Indo-Pacific region. The two major factors influencing foraminiferal production...
