Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...
Spills: The Human-Machine Interface State of Our Knowledge
The International Joint Commission on the Great Lakes has entered into agreements on Great Lakes water quality. Many of the 3000 significant spills that occur in the Great Lakes Basin...
Human Error: A Major Cause of Spills
Accidental spills and releases of toxic and hazardous releases is a much greater problem than realized. While data reporting systems do noe adequately account for human error as a causal...
Oil Spill Impacts on Aquifers
This study attempts to evaluate the seismic hazards along a forty inch pipeline and the impact of a pipeline rupture in the recharge area of the aquifer serving most of West Tennessee....
Application of a Water Budget for Instream Flows
A portion of a water supply reservoir can be dedicated to supplying instream flows. This subreservoir is operated to provide instream fish habitat below the reservoir when releases to...
Application of Risk Management and Value Engineering Techniques to Evaluation of Water Resources Projects with Special Emphasis on Geological Hazards
The purpose of this paper is to provide: 1) a perspective for identifying and evaluating in comparable terms all hazards at a site; and 2) a means for intelligent decision-making based...
Optimization of Freshwater Inflow to Estuaries
This paper presents a methodology that can be used for determining the optimal freshwater inflows into bays and estuaries for the purpose of balancing freshwater demands with the harvest...
Key Environmental Development Issues
Environmental statutes dealing with the control of pollutants generally regulate precriptively, establishing both technical standards, relating to discharges and their effect on the environment,...
The Use of the IWR-Main System as a Planning Tool in Phoenix, Arizona
The IWR-MAIN water demand forecasting model is used extensively as a long-range planning tool by the Phoenix Water and Wastewater Department. Its specific applications include: conservation...
The Center for Advanced Decision Support for Water and Environmental Systems
In July of 1988, the US Bureau of Reclamation awarded the University of Colorado a 4 year, 4 million dollar Cooperative Agreement for the development of a Center of Excellence in the Application...
Conductivity and Transit Time Estimates of a Soil Liner
A field-scale soil linear was built to assess the feasibilty of constructing a liner to meet the saturated hydraulic conductivity requirement of the U.S. EPA (i.e., less than 1 ? 10-7...
Water Reallocation of the Carson River
The federal courts have not been able to allocate the waters of the Carson or Truckee Rivers in such a manner as to satisfy all the users. As a result, there have been a number of suits...
Unmixing Mixed Waste
A thermal treatment process successfully converted sludge classified as hazardous chemical/radioactive mixed waste to low specific activity radioactive waste at the National Guard Armory...
Bio Bonanza?
Bioremediation was used on a portion of the Exxon oil spill, causing the popular press to take notice of the ability of bugs to eat away at oil and, possibly, toxic wastes. The Alaskan...
Successful Siting Incentives
Citizen opposition to the siting of facilities that store, produce or use hazardous materials is both widespread and problematic. There are siting incentives that have worked to allay...
Vaporizing VOCs
The authors summarize the findings of a study for the Environmental Protection Agency on vapor extraction of volatile organic compounds from soils. The potential for ground water contamination...
Buried Treasure
Kelly describes landfill mining feasibility studies at two New England communities. Recently, due to rising landfill closure costs, a concept of landfill mining has been tested and shown...
Ship It By GIS
Abkowitz, Cheng and Lepotsky describe a GIS system for routing hazardous materials shipments. The safe transport of hazardous materials is emerging as a significant concern impacting local,...
Remediating A Fire Site
Machin and Ehresmann describe remediation of a 15 acre fire site at Fort Huachuca, Ariz. An investigation after the fire showed that all of the debris contained asbestos. Sampling confirmed...
Oilcrete
Threatened by probable tightening of hazardous-waste legislation, oil companies are searching for ways to dispose of or stabilize oil-drilling byproducts. One way is cementitious stabilization...
