Characterization of redox conditions in a petroleum contaminated aquifer: Implications for bioremediation potential
… monitoring due to limited understanding of the terminal electron accepting processes (TEAPs) that control biodegradation, which impairs the accurate quantification of contaminant mass loss. The measurement of redox conditions and evaluation of TEAPs are critical in assessing the capacity for …

The effects of augmentation of coarse particulate organic matter in hyporheic sediments
Metabolic and biogeochemical processes in hyporheic zones may depend on inputs of coarse particulate organic matter. Our research focused on how differing quantity and quality of organic matter affects metabolism and nutrient retention in the hyporheic zone of a low-order Appalachian stream. We …

Investigation of Rhenium's Biogeochemistry
… sulfate reduction, in the sequence of microbial terminal electron accepting processes, so I investigated whether Re could be reduced directly or indirectly by iron and/or sulfate reducing bacteria. This hypothesis was also based on the fact that Tc (also Group VIIB), is directly and indirectly …

Sequential Electron Acceptor Model of Intrinsic Bioremediation at a BTEX Contaminated LUST Site in Laurel Bay, South Carolina
… In this research, a three-dimensional sequential electron acceptor computer model, SEAM3D, developed by Waddill and Widdowson (1997) was used to simulate contaminant transport at a leaking underground storage tank site in Beaufort, South Carolina. Gasoline containing benzene, toluene, …

Fate and remediation of emerging organic contaminants in aquatic and soil environments
… research has improved our understanding of the processes controlling the fate and treatment of some classes of synthetic organic chemicals, the fate of many emerging and unregulated micropollutants of concern remain largely unknown. In this thesis research, advancement is made on the mechanistic …

Dynamics of soil processes under extreme meteorological boundary conditions - response of below-ground carbon, sulfur, and iron cycling in fen soils
… provide a mechanistic understanding of the redox processes underlying the response of peatlands to fluctuations of the water table level. Based on laboratory studies, a thermodynamically constrained competition of the different terminal electron accepting processes for common electron donors was …
