Permafrost: A Suitable Landfill Containment Barrier
Ice-rich permafrost is a suitable medium for the containment of wastes. The combination of frigid dry Arctic climate and the impermeability of ice-cemented permanently frozen ground can...
Effluent Dispersion Measurements Under Sea Ice
Field measurements of the dispersion of effluent from the Seawater Treatment Plant (STP) at Prudhoe Bay, Alaska, were made during April 1985. The primary objective was to determine whether...
Waterfront Stabilization Project, Kaktovik, Alaska
This paper discusses an innovative 384-foot treated-timber cribwall design utilized to control rapidly accelerating thermal erosion and establish a roadway along the bluff on the Beaufort...
Water and Wastewater, Time to Automate?
Water and wastewater engineers have been slow to adopt a full circle systems approach to automated monitoring and control. Such a technical tactic for controlling water and wastewater...
Innovative Solutions to the Challenges of Heavy Civil Projects
Each heavy construction project presents unique conditions and challenges. For large projects, the work scope may justify an extensive engineering analysis and significant investments...
Construction Insurance: An Alternative Unified Risk Insurance
The transfer of risk mechanism (insurance) can be applied to solve problems unique to the construction environment. The proposed program is worthy of support since all segments of the...
Fault Diagnosis of Hazardous Waste Incineration Facilities Using a Fuzzy Expert System
The use of an expert system along with fuzzy fault tree analysis is discussed in connection with fault diagnosis of a hazardous waste incineration facility. This fault tree is a diagrammatic...
An Expert System for Inactive Hazardous Waste Site Characterization
The area of hazardous waste management is a broad and multidisciplinary field requiring expertise in engineering, geology, chemistry and toxicology, and is an ideal area for the application...
A Salt Solution for Nuclear Wastes
The Department of Energy's Waste Isolation Pilot Plant in Southeastern New Mexico is the nation's first full-scale facility for disposing of radioactive waste...
Clean-up in the Rockies
The shallow aquifer flowing beneath the Rocky Mountain Arsenal, just outside of Denver, has become contaminated with a number of toxic substances. Until the arsenal can be cleaned-up,...
Cleaning Up Toxics
Case histories show how several different types of contamination cleanup were handled. In Attleboro, Mass., washwater, used to decontaminate equipment and tools after cyanide was removed...
Fire on the Water
Incineration is a promising hazardous waste disposal technique. However, nobody wants an incinerator constructed near him, so waste handlers are considering burning hazardous wastes at...
Treatment in Your Own Backyard
Everyone wants the nation's hazardous waste sites cleaned up, but nobody wants the wastes disposed of near them. Therefore, cleaning up these problems at the site may be the...
Attapulgite: A Clay Liner Solution?
Poor performance of clay liners at waste management facilities has resulted in the EPA mandate of synthetic polymeric liner materials to comply with zero penetration requirements. Laboratory...
Risk Assessment: Engineering Tool
In factoring in human-health impacts when tackling an environmental problem, risk assessment is often the best approach. Its use is growing fast. The technique increasingly is being used...
Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....
Expert Systems in Civil Engineering
The importance of expert systems, also referred to as knowledge based expert systems, has been growing in all areas of civil engineering practice. The papers in this book were presented...
Treating Sewage in One Tank
A sequencing batch reactor (SBR) was the answer to a sewage problem that was holding up community development in Poolesville, MD. Poolesville was one of the first municipalities in the...
Drying Out
Treatment plants are most efficient when they're treating waste, not water. Spurred on by increased fuel prices, a number of new technologies have been developed that can...
Bugs and Carbon Make a PACT
At its Chambers Works in southern New Jersey, DuPont was ordered to sharply reduce the BOD load in the wastewater it discharged to the Delaware River. Out of this mandate came the PACT...
