Ozonation and Photodegradation of Oil Compounds by Surface Level Ozone and Engineered Catalysts in Marine Ecosystem 

Ji, Haodong (2018-11-27)
Marine oil spill has been an environmental challenge for many decades. As the use of oil dispersants has become one of the main approaches to clean up spilled oil, the environmental behavior of dispersed oil remains poorly ...

Physical and Numerical Modeling of Buoyant Groundwater Plumes 

Brakefield, Linzy (2008-05-15)
In coastal states, the injection of treated, relatively fresh, wastewater into deep saline aquifers offers a disposal alternative to ocean outfalls and discharge directly into local waterways. The density contrast causes ...

Pilot-Testing an Ion Exchange Technology for Selective and Regenerative Arsenate Removal and an Engineered Approach for Stabilizing Arsenic-Laden Process Waste Residuals 

Luo, Chunhui (2008-12-15)
Pilot-scale tests of a regenerable and selective polymeric ligand exchanger (PLE) were conducted to remove As(V) at the well field of El Paso Water Utilities (EPWU) in El Paso, TX, USA. The PLE was prepared by immobilizing ...

Potential Negative Effects of Adding Phosphate-Based Fertilizers to Lead In Metal-Contaminated Soils 

Kilgour, Douglas (2007-08-15)
The potential negative effects of adding phosphate amendments for lead (Pb) remediation in Pb-contaminated soils were studied using column and batch experiments. Soils contaminated with high levels of lead as well as ...

Preparation, Characterization, and Applications of Polysaccharide-stabilized Metal Nanoparticles for Remediation of Chlorinated Solvents in Soils and Groundwater 

He, Feng (2007-12-15)
Removal of chlorinated solvents in groundwater and soils represents one of the most challenging environmental issues. Highly reactive palladized iron (Fe-Pd) nanoparticles offer the potential to migrate in the soil and ...

Removal of Copper(II) and Lead(II) from Soils by Poly(Amidoamine) Dendrimers and Reductive Immobilization of Chromium(VI) by Stabilized Zero-Valent Iron Nanoparticles 

Xu, Yinhui (2006-08-15)
This research investigated the feasibility of using poly(amidoamine) PAMAM dendrimers for removal of copper(II) and lead(II) from soils, and using a new class of stabilized zero-valent iron (ZVI) nanoparticles for reductive ...

Runoff Generation in Pastures of the Appalachian Plateau Region of North Alabama 

Sen, Sumit (2009-05-04)
A detailed hillslope-scale hydrologic study was conducted in a pasture at the Sand Mountain region of north Alabama, USA. A 0.12 ha hillslope was intensively instrumented using 31 distributed surface and subsurface runoff ...

Selective Removal of As(V) from Water by Polymeric Ligand Exchange and Engineered Treatment of Spent Regenerant 

An, Byungryul (2006-08-15)
Arsenic introduced by natural or human activities into drinking water sources has been a challenging issue around the world. In the western United States, high arsenic concentrations in drinking water have caused serious ...

Sorption/Desorption and Photodegradation of Dispersed Oil Components in Marine Ecosystem 

Zhao, Xiao (2015-08-06)
This effects of a prototype oil dispersant on solubilization, sorption, and desorption of three model Polycyclic aromatic hydrocarbons (PAHs) in sediment-seawater systems were investigated. Increasing dispersant dosage ...

Towards Improved Application of Super Absorbent Polymers in Agriculture and Hydrology: A Cross-Disciplinary Approach 

John, Gerald Francis (2011-11-16)
Fresh water is the essential and key component to support life on this planet. It constitutes about 0.01% of world’s total water. Though freshwater is renewable, it is finite. In recent years, the demand for fresh water ...

Understanding the Flow and Mixing Dynamics of Saline Water Discharged into Coastal Freshwater Aquifers 

Hogan, Matthew (2006-12-15)
Typically the origin of saltwater intrusion into coastal aquifers has been attributed to the reduction of freshwater flux (or head) in the aquifer. This intrusion is the most common natural source of saltwater contamination ...

Use of a Small-scale Erosion Control Model in the Design of Silt Fence Tiebacks 

Halverson, Jarid (2006-05-15)
For most storm events, accelerated erosion caused by storm water runoff from construction sites can be mitigated through vigilant management efforts. The control measures that are designed to provide a practical field ...

Use of Hydroxyapatite Derived from Catfish Bones for Remediating Uranium Contaminated Groundwater 

Shyam sundar, Ayalur Chattanathan (2009-05-20)
Hydroxyapatite derived from catfish bones was used for removing uranium from contaminated groundwater. Literature review indicated that apatites from various sources of fish bones can be used for metal remediation. The ...
