Nanotechnology Takes Roots
Nanoscale particles of zero-valent iron with a trace of noble metal catalyst are punching well above their weight in the area of environmental remediation. Their ability to destroy a wide...
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,...
Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...
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,...
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...
Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...
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....
Supercharged
The Groundwater Replenishment (GWR) System is a regional water supply project sponsored jointly by the Orange County Water District (OCWD) and the Orange County Sanitation District (OCSD)....
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....
