Geotechnical Design Over Karst. It's All About the Water
Karst is a type of topography which is formed over soluble rocks, such as limestone, dolomite, or gypsum. An irregular bedrock surface is typical of most karst areas, along with sinkholes,...

A Probabilistic Approach to Karstic Foundation Variability
Karst is a landscape formed in soluble rocks caused by movement of water that has become slightly acidic. Limestone, dolomite, and gypsum are vulnerable to these influences and may be...

Effect of Solubility on Enhanced Electrokinetic Extraction of Metals

Use of NaOH to Control pH for Solubilization of Waste Activated Sludge
Waste activated sludge was collected from the final clarifier of a local municipal wastewater treatment plant. NaOH was used in comparison made of the controlled pH batch experiments with...

Rate-Controlled Micellar Solubilization of an LNAPL in Aquifer Materials

Neptunium, Plutonium, and Americium Solubility and Speciation Studies in a Neutral Electrolyte with a Total Carbonate Concentration Simulating UE-25P#1 Well Water

Measurement of Oxygen Solubility in Non-Ideal Systems

Removal Of Chromium From Groundwater Using Permeable Barriers: An Aquifer Simulation Study
Previous efforts to remediate groundwater contaminated by chromium-bearing industrial wastes have involved post-extraction methods, whereby groundwater is pumped to the surface treated...

Effect of Alkalinity on Copper Corrosion

Modeling Issues of Copper Solubility in Drinking Water
The paper discusses the application of a model to the solubility of copper in drinking water. This paper is the result of numerous forms of pitting corrosion and pipe failures. Monitoring...

Radionuclide Migration to the Aquifer Through the Porous Medium
Time dependent doses of radionuclides from a waste container to the aquifer through porous medium are analyzed for (1) congruently released transuranic elements such as Np-237 and (2)...

Geochemistry for High Level Waste: An International Comparison
This paper presents a brief summary of some of the recent and on going geochemical research related to the disposal of high level radioactive waste. For most categories of research (basic...

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...

Dissolution Rates of As-Received and Partially Oxidized Spent Fuel

Solubility of Uranyl in Brine

Behaviour of Plutonium, Rare Earth Elements and Elements of the Platinum Group in Vitreous Phosphate Composites During Liquid HLW Vitrification
The methods of γ-spectrometry, γ-scanning, α-radiography, optical microscopy, x-ray phase and x-ray fluorescent analyses were used to study the behaviour of Pu, La, Ce, Nd, Sm, Ru, Rh,...

Near-Field Transport of Radioactive Chains
Much attention has been given to predicting the near-field mass transfer of a single radioactive species from a waste solid into surrounding porous material, but only limited consideration...

Use of Stable Isotopes, Tritium, Soluble Salts, and Redox-Sensitive Elements to Distinguish Ground Water from Irrigation Water in the Salton Sea Basin
Evaporative concentration of irrigation water diverted from the Colorado River to the Salton Sea basin for several decades has produced an overlying system (that includes drainwater and...

Isotropic Fractionation During Air-Water Transfer of Oxygen and Nitrogen
We present empirical results that show the kinetic fractionation during gas exchange is 0.9972 ± .0002 for oxygen and 0.9987 ± .0001 for nitrogen. These values are larger than the solubility...

Measurement of Reaeration Coefficient with the Soluble Solids Probe
The results of analytical and experimental studies are presented, showing that the proposed method for indirect determination of gas transfer coefficients at gas-liquid interfaces, based...
