Environmental Compliance Monitoring Program for Offshore Oil and Gas Exploration and Development and Production Activities in the Pacific OCS Region
The Pacific Outer Continental Shelf Region of Minerals Management Service has recently development and is implementing an Environmental Compliance Monitoring Program. Each of the 24 oil...

Pumping or Slurry Walls—Which Works Best for Groundwater Containment?
Results of a numerical optimization model capable of designing containment systems for sites with three-dimensional groundwater flow indicate that site hydrogeology and economic considerations...

In Situ Bioremediation Via Horizontal Wells
The U.S. Department of Energy, Office of Technology Development, has been sponsoring full-scale environmental restoration technology demonstrations for the past 3 years. The Savannah River...

Anisotropic Effects on Flow from a Recirculation Well
We examined flow in an unconfined aquifer near a recirculation well, which consists of a source and a sink of equal strength, with emphasis on understanding the effects of anisotropy....

In-Situ Bioremediation Using a Recirculation Well
An existing model (Semprini and McCarty, 1991; 1992) of in-situ bioremediation using methanotrophic bacteria for degradation of volatile organic compounds was modified to simulate use...

Kern County Water Agency—1991 Emergency Ground Water Recovery Program
The 1991 Emergency Ground Water Recovery Program was conceived and implemented by the Kern County Water Agency to deliver water to four water districts to save permanent crops. The Program...

Optimal Contaminant Plume Management with US/WELLS
A micro-computer based software package developed at Utah State University for computing optimal pumping strategies for well systems (US/WELLS) is demonstrated. US/WELLS is used to determine...

Sustained Yield of the Provo Groundwater Basin
The sustained yield of the Provo Groundwater Basin has been determined by a correlation analysis of the change in groundwater levels with the April-October stream flow at the mouth of...

Distribution of Stable Isotopes in Ground Water in the Rialto-Colton Basin, California
Since 1982, imported water originating in the Sierra Nevada has been used to recharge the Rialto-Colton ground-water basin, about 100 km east of Los Angeles. Stable isotopes of oxygen...

Ground Water Management in the Salt Lake Valley, Salt Lake County, Utah
The perfected and approved water right applications in Salt Lake Valley could potentially withdraw from the principal aquifer a quantity of water far greater than the annual recharge....

Distribution and Mobilization of Dissolved Selenium in Ground Water of the Irrigated Grand and Uncompahgre Valleys, Western Colorado
Distribution of dissolved selenium in ground water of the irrigated Grand and Uncompahgre Valleys is affected by the aqueous geochemical environment of the shallow ground-water system...

Streamflow Depletions Considered in Water Transfers
In the State of Colorado, streamflow depletions are defined as that amount of water diverted to beneficial use minus return flows to the stream system. This paper summarizes the engineering...

Streamflow Depletions Resulting from Ground Water Transfers
An application to move the point of diversion of a quasi-municipal ground water right from about 4.8 km to a second well about 0.3 km from a river channel was made in the Reno/Sparks,...

Well Response in a Leaky Aquifer and Computational Interpretation of Pumping Tests
An analytic solution is derived describing flow in a horizontal confined leaky aquifer of infinite extent around a fully penetrating well of negligible storage capacity. The differences...

Concentration History During Pumping from a Leaky Aquifer with Stratified Initial Concentration
Analytical and numerical solutions are employed to examine the concentration history of a dissolved substance in water pumped from a leaky aquifer. Many aquifer systems are characterized...

An Overview of Methods to Delineate Capture Zones of Pumping Wells
Rainfall over the surface area of an unconfined aquifer, which contributes flow to a pumping well under Dupuit conditions, was estimated. Using a two-dimensional analytical model with...

Designing Self-Cleaning Wet Wells for Wastewater Pumping
Guidelines for the design of self-cleaning wet wells for variable speed pumps are given. The progress of research on the design of wet wells for constant speed pumps, including submersible...

Modeling Saltwater Intrusion Control Measures in the West Coast Basin
In the 1960's and 1970's the West Coast Basin Barrier was constructed to protect tha major coastal groundwater basin from further salt water intrusion, which had been occurring as a result...

Variability in Solutions of Constrained Optimization Problems: Ocean Outfall Design Case
Uncertainty in optimization model resulting from parameter uncertainty has not been well studied in the hydraulics and water resources areas. To make valid decisions, knowledge of the...

Cleaning Up in the Former Soviet Union
As they negotiate with authorities in Russia, Azerbaijan, Kazakhstan and other former Soviet Republics, Western companies—including many of the big oil and natural-resources firms—are...
