Pinpointing Nonpoint Pollution
The Tennessee Valley Authority is using aerial photography to locate nonpoint sources of water pollution. These cause most of the water quality problems in the region. Failing septic tanks...
Biological Treatment of Hazardous Wastes
Biological treatment�using nature's bacteria and fungi�sometimes costs as little as 10-20% as incineration. Wastes in any form�solid, aqueous and gaseous�can be treated biologically....
Managing Mixed Waste
The category of mixed waste is an ambiguous one that is not clearly defined nor assigned to any one federal agency. These wastes, according to definitions in several government documents,...
Future Shock for Farmers
An expert panel of water and agricultural practices specialists met and predicted how the nation should and might deal with problems associated with nonpoint pollution sources, especially...
Underground Storage Tank Program and Its Implications
National concern over leaking underground tanks storing hazardous materials and wastes has resulted in the implementation of the 1984 Amendments of RCRA, which include the requirement...
Megaproject Management Tool
Program management oversight is an administration innovation in the water and wastewater treatment field. The method is increasingly being used when a public entity takes on a project...
Energy/Environment Opportunities for Civil Engineers
In the West, Nuclear Facilities Decommissioning; In the East, Implementation of Waste to Energy Systems
The papers in this book examine and provide illustrations for civil engineering opportunities in resolving apparent conflicts between needs for energy generation and environmental acceptability....
Disposal and Utilization of Electric Utility Wastes
The papers presented in this book summarize the recent developments in coal ash utilization technology, and the current issues and regulations associated with the environmental effects...
Leaching of Nitrate from Freely Drained?Irrigated Fields Treated with Municipal Sludges
A municipal sludge land application experiment was initiated in 1975 near Riverside, California. From 1975 to 1983 sludges from the Los Angeles Metropolitan Area were applied on experimental...
A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...
Inflatable Form Construction in Space
In 1973, NASA launched Skylab 1 using a modified third stage of a Saturn V Rocket. This orbital workshop proved to be a success even though problems occurred. This article discusses the...
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...
Supercritical Water Oxidation: Space Applications
The process of Supercritical Water Oxidation (SCWO) is approaching terrestrial commercialization for the destruction of toxic and hazardous waste chemicals. The technology appears promising...
Waste Management: Project Mercury to the Space Station
This paper presents my perceptions of the design of waste management systems for manned space flights. I'll follow the evolution of waste management from the early Mercury...
Plasma Reactor Waste Management Systems
The University of North Dakota is developing a plasma reactor system for use in closed-loop processing which includes biological, materials, manufacturing, and waste processing. Direct-current,...
Space Operations - Care and Handling of Remains
On earth, effective methods have accommodated all functional and operational facilities and entities necessary for the handling of human remains. None have been overlooked or omitted....
Burning Coal's Waste
Culm is the waste coal and shale left behind in mountain-size piles when anthracite mining ceased in northeastern Pennsylvania. Owners of a cogeneration plant now under construction near...
Waste Processing: Makes Good Energy
Materials separation in solid wastes streams will generate more BTU's at waste-to-energy facilities. The removal of noncombustibles like bottles, batteries and refrigerators...
Environmental Health Programs of the USEPA
The major programs of the U.S. Environmental Protection Agency (EPA) designed to reduce risk to public health are summarized with emphasis on their content, funding and effectiveness in...
