Assessing the effectiveness and environmental impacts of using natural flocculants to manage turbidity

Creator:: Kegley, Laura J.
Abstract:: The objective of this research was to determine the feasibility of using chitosan as a natural flocculant to control turbidity during in-stream construction work. A series of field tests in Oak Creek, Corvallis, OR were conducted in order to test the effectiveness for turbidity control and the environmental impacts of...

Uranium and technetium bio-immobilization in intermediate-scale permeable reactive scale barriers

Creator:: Sapp, Mandy M.
Abstract:: Groundwater at Oak Ridge National Laboratory's Field Research Center (FRC) is contaminated with U(VI) and Tc(VII), has pH values as low as 3.3, and nitrate concentrations as high as 120 mM. The objective of this research was to determine if in-situ bio-immobilization is a viable treatment alternative for this water....

Limiting copper loss from treated wood in or near aquatic environments

Creator:: Mitsuhashi Gonzalez, June M.
Abstract:: Copper migration from treated wood has created concerns within the environmental community because of the potential effects of this heavy metal on aquatic organisms. Migration can be limited, to some extent, by more controlled treatments and by post-treatment processing, but these actions cannot completely overcome the problem. An alternative approach...

Detection of deforestation and land conversion and estimation of atmosperic emissions and elemental pool losses from biomass burning in Rondônia, Brazil

Creator:: Guild, Liane S.
Abstract:: Biomass burning associated with deforestation and land use in the Amazon, greatly contributes to emissions as well as depletion of elemental pools. We identified deforestation and pasture formation and quantified resultant burning emissions and terrestrial aboveground elemental pool losses during a period of early colonization in the vicinity of Jamari,...

Improving ecological risk assessment of pesticides for nontarget terrestrial vertebrates

Creator:: Wang, Guiming
Abstract:: The Quotient Method (QM) is used by the United States Environmental Protection Agency (USEPA) in ecological risk assessments of pesticides for nontarget organisms. The QM requires several assumptions regarding exposure and hazards of pesticides to wildlife; several of these assumptions have not been tested. During 1997-99, I conducted three experiments...

A model for simulation of subsurface transport of highway-related water quality constituents

Creator:: Hesse, Edwin Todd
Abstract:: A spreadsheet-based transport model was developed in Microsoft Excel™ as part of a six-year National Cooperative Highway Research Program project conducted at Oregon State University. The model simulated the leaching, transport, removal, and retardation processes that occur in the surface and subsurface pathways of the near highway environment. For all...

Ammonia control best management practices

Creator:: Downing, Troy (Troy Woerner) and Gamroth, Michael J.
Abstract:: "There is growing interest in odor and gaseous emissions from livestock operations because of concern about global warming and enforcement of the Clean Air Act. This bulletin provides and evaluates best management practices for the control of ammonia lost to the air on dairy farms. Benefits are based on an...
