Modeling hydrodynamic fluxes in the Nueces River Delta
(2011-08)
Increasing municipal and regional water demands have reduced freshwater inflows to the Nueces Delta. These flow reductions impair the marsh ecosystem’s functionality. As part of a United States Army Corps of Engineers ...
Ozonation of erythromycin and the effects of pH, carbonate and phosphate buffers, and initial ozone dose
(2011-08)
The ubiquitous presence and chronic effect of pharmaceuticals is one of the emerging issues in environmental field. As a result of incomplete removal by sewage treatment plants, pharmaceuticals are released into the ...
Kinetics of ciprofloxacin degradation by ozonation : effects of natural organic matter, the carbonate system, and pH
(2010-08)
The presence of pharmacologically active and persistent compounds in drinking water sources is an environmental and public health concern. Sources of pharmaceuticals in the aquatic environment include wastewater treatment ...
Hydrological connectivity in vegetated river deltas : the effects of spatial variability and patchiness on channel-island exchange
(2018-05-04)
River deltas are threatened regions of great societal and environmental importance, and their continued survival depends upon a greater understanding of their formation and evolution. Hydrological connectivity in river ...
Chemical usage and savings at the Austin Water Utility drinking water treatment plants
(2012-05)
The goal of this research was to maintain excellent water quality at reduced chemical operations cost. Chemical usage data at the Austin water treatment plants were examined by identifying trends and investigating suspected ...
The effect of treatment on the quality of harvested rainwater
(2012-05)
Harvested rainwater is an alternative water resource that can be utilized to help meet the world's growing demand for fresh water. Although harvested rainwater is often considered to have adequate physical and chemical ...
Reducing turbidity of construction site runoff via coagulation with polyacrylamide and chitosan
(2012-05)
The U.S. Environmental Protection Agency is in the process of developing a nationwide standard for turbidity in construction site runoff. It is widely expected that this standard cannot be met with conventional erosion and ...
Monolayer and multilayer particle resuspension from indoor surfaces : literature review and experimental methodology
(2010-12)
Resuspension is an important source of particles in the indoor environment. A variable that may have a significant impact on the fraction of particles removed from indoor surfaces is the type of particle deposit. Particles ...
Chukchi Sea environmental data management in a relational database
(2013-05)
Environmental data hold important information regarding humanity’s past, present, and future, and are managed in various ways. The database structure most commonly used in contemporary applications is the relational database. ...
Biological and physical characterization of aerosols generated in showers
(2014-05)
Although drinking water treatment facilities treat raw water sources to remove and inactivate microorganisms, some microorganisms will survive treatment and enter the distribution system. Regrowth and infiltration in ...
