Sodium Toxicity in Methanogenic Systems: Rates and Modeling

Effects of Hydraulic Gradients on Pore Fluid Chemistry

Methods to Evaluate the Environmental Impact of Sodium Silicate Chemical Grouts

DOE Lab Develops System to Sack Sodium Nitrate

Controlling Lead and Copper Corrosion and Sequestering of Iron and Manganese
With the recently enacted Lead and Copper Rule (LCR), many utilities are faced with the conflict of meeting the requirements of the Rule and controlling aesthetic problems caused by source...

Radionuclide Solubility and Speciation Studies for the Yucca Mountain Site Characterization Project
Yucca Mountain, Nevada, U.S.A., is being investigated for its suitability as a potential site for a geologic nuclear waste repository. As part of the site characterization studies, actinide...

Hanford Ferrocyanide Reactivity: Effects of Other Tank Constituents
In this study simulated wastes were used to determine the effect of potential waste constituents on the reactivity and explosivity of Hanford ferrocyanide-bearing wastes. Test results...

Grouting Against Hazwaste
Grouting has only recently entered the hazardous-waste arena, mainly in the form of positive cutoff slurry walls. At an industrial landfill near Niagara Falls, N.Y., a three sided, single-line...

Hydrogen Generation from Sea Water by Means of a Metal Hydrolysis Process
Active metals such as magnesium reacted with steam can produce hydrogen. This reduction of water by magnesium or aluminum is a thermodynamically favorable process, however, formation of...

Mapping Ground-Water Sodium Adsorption Ratios in Northern Louisiana
High sodium concentration is suspected as the cause of several crop failures in the northern part of Louisiana. This study, using Geographic Information Systems (GIS) technology, was undertaken...

Validity of Electro-Osmosis for Soil Decontamination
The subject matter of this paper is electro-osmosis in fine grained soils. A simple instrument has been developed to simulate this phenomena in the laboratory. A series of experiments...

Program to Reduce Deicing Chemical Usage
Over the years (since about 1948), the dependency on deicing chemicals has been increased to provide 'bare pavement' for safe and efficient winter transportation....

Irrigation Intervention Analysis of Drainage SAR
G.E.P. Box-G.M. Jenkins time series analysis, with irrigation applications as an intervention function, was used to study temporal and spatial variabilities of sodium adsorption ratios...

Controlling Sulfide Corrosion in Large Diameter Gravity Sewers (abstract)
The County Sanitation Districts of Los Angeles County undertook a major evaluation of sewer system ranging in size from 1. 22 to 3. 65 meters in diameter that transports peak wastewater...

Sodium Concrete Reaction — Structural Considerations
An overview of the sodium concrete reaction phenomenon, with emphasis on structural considerations, is presented. Available test results for limestone, basalt, and magnetite concrete with...

Corrosion of Reinforcing Steel in Fly-Ash Concrete

Ion Exchange and Membrane Processes for Nitrate Removal from Water

A Comparison of Finite Element J-Integral Evaluations for the Blunt Crack Model and the Sharp Crack Model

Mixing in the Epilimnion of the Dead Sea

Heat Treatment and Anaerobic Digestion of Refuse
Alkaline heat treatment was evaluated as a pretreatment process for increasing the anaerobic digestibility of municipal refuse. The goal was an increased methane yield from refuse lignocellulose....
