It's a Bug's Life — Enhanced In-Situ Bioremediation of Chlorinated Solvents in Groundwater

Firepower
The processes put in place by water utilities are designed with the quality of water normally received for treatment in mind. But the runoff from areas ravaged by fire can degrade that...

Optimal Selection of Rechlorinization Station in Water Distribution System by Optimization Techniques
The optimal rechlorination in water distribution systems was investigated by incorporating optimization techniques into a numerical water quality model (EPANET2). Four types of optimization...

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....

Long-Term Groundwater Monitoring
The State of the Art
Prepared by the Task Committee on the State of the Art in Long-Term Groundwater Monitoring Design of the Environmental and Water Resources Institute of ASCE. ...

Tapping the Desert
As part of an effort to augment the limited supply of freshwater in El Paso, Texas, engineers and planners are eyeing a new source: desalinated water pumped from beneath the desert floor....

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...

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...

Leakage Control—Finding a New Resource from the Existing One
It is estimated that by the year 2005, one person in two will have an insufficient supply of one of the world's most precious elements: water. Worse still, it is predicted that this shortage...

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,...

A Decision Support System for Drought Management Planning
Traditional drought management planning has focused on curtailment of demand by instituting voluntary or mandatory restrictions on water consumption when regional hydroclimatic indicators...

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...

Decision Support System for Daily Real-Time Operations in the Geum River Basin, Korea
A joint international collaboration between the Korea Water Resources Corporation (KOWACO) and Colorado State University (CSU) has resulted in development of a decision support system...

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...

Replacing a Dying Water Infrastructure
The water infrastructure in the United States will soon need massive repairs. Pipes are leaking, and most pipes are near the end of their life cycles. Tens of thousands of sewer overflows...

Development and Application of a Decision Support System for Municipal Water Infrastructure Planning: Challenges and Successes
Many water utilities across the country continue to face the challenge of intelligent planning for cost effective, efficient operation, larger demands, stricter government regulations,...

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....

A River Runs through It
The new stadium under construction for the New England Patriots is architecturally and structurally unique, but it is also attracting attention for another reason: the restoration of a...

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)....

The Nisqually, Washington, Earthquake of February 28, 2001
