Data from Most Monitoring Wells in Limestone Terranes Are Irrelevant to Pollutant Detection but Reliable Monitoring Can Be Attained: Why and How
The conventional system of using three or more monitoring wells placed down-gradient from a site and one or more background wells placed up-gradient from it is extremely unlikely to detect...
An Experimental Study on the Effect of Wastewater Application in Dry Wells and Its Impact on Groundwater
A study was conducted in order to gather accurate information on the effectiveness of dry wells for use in wastewater disposal and the effect of such disposal practice on groundwater....
Gas Transfer and Secondary Currents in Open Channels
Laboratory flume experiments on water-wide controlled gas transfer, such as reaeration, are described. The experiments indicate that gas transfer is a surface renewal process, well described...
Modification of the Step Drawdown Test for Pump Selection
This paper suggests a slightly modified mathematical model for pump tests whose aim is to design the correct pump for a well. The advantage of the model presented is that it incorporates...
Monitoring Groundwater Quality in the Southwest
Monitoring groundwater quality near sources of pollution in the southwest commonly involves highly productive alluvial aquifers. Experience in monitoring in such a setting indicates that...
The Risk Factor in Water Resources
Risk is inherent in nature and society, while uncertainty depends on investigations. Decision making in water resources is most often a deterministic selection of dimensions which divide...
Stormwater Management in Orlando, Florida
Metropolitan Orlando, Florida contains 82 lakes and approximately 200 drainage wells which serve as ultimate outfall for stormwater runoff. The quality of the surface receiving waters...
A Digester Gas Cogeneration Plant at EBMUD
Final testing and start-up of a 4. 3 MW digester gas cogeneration plant has been completed and full-time operation begun at the EBMUD Wastewater Treatment Plant in Oakland, California....
Analysis of a Production Well Through Sediments Containing Gas Hydrates
In some of the petroleum reservoirs recently discovered north of the Arctic Circle, production wells extend through thick permafrost. Several authors have reported zones of gas hydrate...
Design of an Icebreaking Offshore Supply Vessel
There are two basic scenarios for icebreaking support vessels. The first is the delivery of drilling fluids and supplies to drilling units and other development operations. The second...
Single Point Mooring in Ice Infested Waters
Several design studies have investigated the use of Single Point Mooring (SPM) systems in waters having significant seasonal ice intrusions. Investigations were carried out for both temporary...
Tanker Mooring/Loading Systems for Northern Offshore Arctic Regions
Transportation of crude oil in arctic areas via shuttle tankers can prove to be a viable alternative to a pipeline system. The shuttle tanker system will require offshore terminals equipped...
Bowhead Whales and Other Endangered Whale Species: Their Influence on Offshore Operations in Alaska
In recent years, whales have become the focus of considerable public concern, and this is manifested in the measures that are imposed to protect them from possible adverse effects of offshore...
SHADS: Mobile Arctic Drilling Platform
To minimize costs of Beaufort Sea exploration programs, the industry needed a mobile arctic drilling structure that requires little or no site preparation, does not require an active ice...
Constructibility of Arctic Offshore Structures
The costs of structures designed for Arctic Offshore Drilling and Production Platforms have reached extreme levels. A major component of the costs of such structures is their constructibility....
Offshore Seawater Intake in the Arctic
Waterflood has become a proven technique for enhancing oil recovery from oil producing reservoirs. At Arctic north slope areas, seawater has been used successfully for such operations....
Effects of External Loadings on Large-Diameter Buried Pipelines
Development of oil and gas resources in the far north has involved extensive use of buried steel pipelines. Buried pipelines, particularly onshore, are frequently subjected to heavy superimposed...
Geotechnical Characteristics of Seafloor Sediments: Norton Sound, Alaska
During the past few years the USGS has been conducting studies in the northern Bering Sea aimed at identifying geologic and environmental conditions that may be hazardous to offshore resource...
Bering Sea Crude Oil Transportation Systems
A study to evaluate and compare the technology and costs associated with crude oil transportation alternatives in the Bering Sea has been conducted. Existing and proposed offshore loading...
Maintaining a Natural Gas Pipeline in Active Landslides
This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe...
