Variability of Copper in the International Reach of the Similkameen River, British Columbia
All total copper concentrations measured in soft water during spring freshets were above the Canadian Water Quality Guidelines. Approximately 57% of all 108 observations over the three-year...
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...
Adsorption, Desorption and Transport of Pesticides in Groundwater: A Critical Review
Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption...
Riverbank Instability Due to Bed Degradation
Degradation lowers the bed of an alluvial channel over a long reach. This has the effect of increasing the bank heights and angles, which decreases the stability of the banks with respect...
Carbonyl Extraction of Lunar and Asteroidal Metals
The century-old Mond process for carbonyl extraction of metals from ore shows great promise as an efficient, low energy scheme for producing high-purity Fe, Ni, Cr, Mn, and Co from lunar...
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....
Oxygen Production for a Future Lunar Base
This paper discusses various ways for providing oxygen for a lunar base. Currently, there are three methods available which are technologically possible. One of these is the use of chemical...
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...
Zapping Hazwastes
Electromagnetic energy, applied in situ, successfully removes contaminants entrapped in soil by vaporizing them. Recent test using radio frequency have successfully removed up to 99% of...
Garbage Management in Japan: Leading the Way
Excerpts from a book that details how land-poor Japan has less garbage problems than the land rich United States. Chapter Six, Incineration, is excerpted. In Japan, incineration is regarded...
Jet Grouting: The Pace Quickens
Over the past year, use of jet grouting in the U.S. has nearly quadrupled. A versatile tool, it has performed well in settings as diverse as a railway tunnel, industrial waste site and...
