Applying Sustainable Development
Experts hoping to lessen the harsh effects of development on Earth's ecosystem have turned to the concept of sustainable development. Engineers are finding old ways to put...
Regulatory Views on Seismic and Fault-Displacement Parameters Needed for a Geologic Repository Design
This paper presents the regulatory views of the U.S. Nuclear Regulatory Commission staff on some of the significant issues related to the seismic and faulting design of a geologic repository....
Scoping the Monitoring Instrumentation to Meet Repository Design and Construction Needs
This paper discusses categories of instruments that are available and recommended for consideration to monitor the engineering performance and interactions of the geologic media, groundwater,...
A Natural Cleanup
For almost 30 years, nonvolatile petroleum hydrocarbons from used motor oil, diesel, gasoline and other automotive fluids had been released to an oil sum at a truck-maintenance facility...
MSA for VOC Removal
In what may be the first large-scale application of its type, mechanical surface aeration�usually used in wastewater treatment�is removing volatile organic compounds from potable ground...
Sampling Sediment on a Complex Site
The remedial design of a complex Superfund site hinged on a variety of sampling methods required by the site's diverse terrain. Cadmium, lead, cobalt and nickel are the culprits...
Seismic Design Considerations for Uplifted Tanks
An evaluation of the most commonly used seismic design procedures for unanchored tanks is presented. It is noted that current standards are inconsistent in predicting the behavior of unanchored...
Seismic Strengthening of Johnstown Tank in Lakeside, California
Seismic overturning moments exerted on liquid storage tanks may be resisted by a system of anchor bolts if the shell could be adequately anchored to its base, or by allowing the base plate...
Concrete Arch Bridges for Supporting Steel Conduits of Mingtan Pumped Storage Project
