The Integrated Performance Assessment in SKI Project-90
The SKI Project-90 is a performance assessment of a hypothetical repository system with KBS-3 features in crystalline rock. A large part of the effort has been to identify and characterize...

Development of a Sorbent for Removal of Nonionic Pollutants from Water
Sorption of anionic surfactants onto mineral oxides and, and the subsequent partitioning of non-ionic organic substance into the organic phase of these synthetic sorbents was studied....

Air-Water Transfer: The Role of Partitioning
A review is presented of the role of air-water equilibrium in determining the direction and rate of transfer of chemicals between water bodies and the atmosphere. Because this diffusive...

Natural Radionuclides in Groundwater From J-13 Well at the Nevada Test Site
The concentrations of U-238 and Th-232 chain members are extremely low in J-13 water, suggesting that their concentrations in groundwaters are largely governed by sorption/desorption processes....

Sorption Rate Studies with Halogenated Organic Chemicals and Sandy Aquifer Material — Implications for Solute Transport and Groundwater Remediation

Mechanism of Chemical Phosphorus Removal in Activated Sludge with Al(III) and Fe(III)

Proton Competition in Cu(II) Biosorption by Fungal Mycelia

Modeling Volatile Organic Transport with Vapor Sorption
A flexible finite element simulation model is developed to predict the movement of volatile organic compounds in variably saturated subsurface regions. The model incorporates both the...

Contact Stabilization Process Analysis and Formulation
In this paper, the contact stabilization process is analyzed. In comparison to the conventional activated sludge process, there are a larger number of independent design variables involved...

Surface Water Particles: Coagulation and Sorption
A size-dependent particle and particle-associated contaminant transport and fate model is presented. The unsteady, two-dimensional model couples the water column and bed and enables analysis...

Sorption and Transport of Aldicarb Through the Vadose Zone
The literature was reviewed regarding the sorption and transport of a nonionic organic pesticide aldicarb, an extremely toxic and relatively water soluble carbamate insecticide that has...

Nuclide Migration from Areal Sources Into a Fracture
The authors show analytic solutions to the problem of hydrogeologic transport of radionuclides released from finite areal sources into a planar fracture. The authors illustrate the solutions...

Vapor Phase Sorption in the Vadose Zone

Radium Removal from Groundwater Using Sorption to Filter Sand
The use of this novel process to remove sufficient radium from drinking water by filter sand has been demonstrated. A major potential advantage of this process is that a minimal capital...

Mixed Solute Interactions in Groundwater Systems
Research results are presented from a study examining the competitive sorption effects of two organic chemicals, para-dichlorobenzene and 2,4-dichlorophenol, to solids from the Cohansey...

Solubility of Aromat6ic Solutes and Sorption onto Soil in Polar Solvent/Water Systems
An investigation was performed to evaluate the solubility and sorption of aromatic solutes onto soil from an aqueous phase containing polar solvent. This work relates to the evaluation...
