Using a single-well push-pull test to estimate mass transfer rate parameters

Creator:: Kelley, Michael John
Abstract:: More efficient methods are needed for the in-situ evaluation of mass transfer parameters which describe the movement of solutes through aquifer material. The objective of this study was to develop a method for estimating diffusion rate and capacity coefficients using a single-well, "push-pull" tracer test. The method consists of the...

A hydrogeologic study and groundwater model of Parrett Mountain, Oregon

Creator:: Healy, Robert Peter
Abstract:: This thesis presents a hydrogeologic study of the Parrett Mountain Region, located approximately 20 miles south of Portland, Oregon. The aim of the study was to investigate the impacts of Columbia River Basalt on the regional groundwater system, to expand our understanding of flow through fractured basalt, to improve management...

Groundwater flow and radionuclide transport in fault zones in granitic rock

Creator:: Geier, Joel E.
Abstract:: Fault zones are potential paths for release of radioactive nuclides from radioactive-waste repositories in granitic rock. This research considers detailed maps of en echelon fault zones at two sites in southern Sweden, as a basis for analyses of how their internal geometry can influence groundwater flow and transport of radioactive...

Quantification of the nitrate attenuation capacity of low-permeability Missoula Flood deposits in the Willamette Valley of Oregon

Creator:: Arighi, Louis M.
Abstract:: Low-permeability geologic units may offer significant chemical and hydraulic protection of adjacent aquifers, and are important for managing groundwater quality, especially in areas with significant non-point source contamination. Nitrate in the Willamette Valley is attenuated across the Willamette Silt, a semi-confining unit overlying a regionally important aquifer. To quantify the...

Temporal and spatial variability of groundwater nitrate in the southern Willamette Valley of Oregon

Creator:: Mutti, Jeffrey Glenn
Abstract:: Groundwater nitrate contamination is a well-documented issue in the Southern Willamette Valley (SWV) of Oregon, as a Groundwater Management Area (GWMA) has recently been declared. As a GWMA, groundwater nitrate monitoring must occur until regional concentrations are below 7 mg/L NO3-N. However, the presence of temporal variability can make it...

Reactive transport modeling in a discrete fracture : applications to the formation of sericitic hydrothermal alteration at Butte, Montana

Creator:: Geiger, Sebastian
Abstract:: A model for the spatial and temporal evolution of the gray sericitic (GS) and sericite with remnant biotite (SBr) hydrothermal alteration selvages within the Butte Quartz Monzonite (BQM) of the porphyry copper deposit at Butte, Montana, is presented. The model provides a mathematical description for the location and advance of...

Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

Creator:: Freiherr von Schwerin, Claudius
Abstract:: Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...

A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

Creator:: Woody, Jen
Abstract:: An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...
