An Analysis Of Co2-Driven Cold-Water Geysers In Green River, Utah And Chimayo, New Mexico, Zachary T. Watson

Theses and Dissertations

The eruption periodicity, CO2 bubble volume fraction, eruption velocity, flash depth and mass emission of CO2 were determined from multiple wellbore CO2-driven cold-water geysers (Crystal and Tenmile geysers, in Utah and Chimayó geyser in New Mexico). Utilizing a suite of temporal water sample datasets from multiple field trips to Crystal geyser, systematic and repeated trends in effluent water chemistry have been revealed. Crystal geyser has a four part eruption cycle composed of a minor eruption period (mEP), major eruption period (MEP), aftershock eruption period (Ae) and recharge (R). Tenmile geyser has a four part eruption cycle composed of MEP, drainage …

Fault-Controlled Advective, Diffusive, And Eruptive Co2 Leakage From Natural Reservoirs In The Colorado Plateau, East-Central Utah, Na-Hyun Jung

Theses and Dissertations

This study investigated a natural analogue for CO2 leakage near Green River, Utah, aiming to understand the influence of various factors on CO2 leakage and to reliably predict underground CO2 behavior after injection for geologic CO2 sequestration. Advective, diffusive, and eruptive characteristics of CO2 leakage were assessed via a soil CO2 flux survey and numerical modeling. The field results show anomalous CO2 fluxes (> 10 g m-2 d-1) along the faults, particularly adjacent to CO2-driven cold springs and geysers (e.g., 36,259 g m-2 d-1 at Crystal Geyser), ancient travertines (e.g., 5,917 g m-2 d-1), joint zones in sandstone (e.g., 120 …

The Spread Of Emerging Contaminants In The Soil-Groundwater System, Lucia Feriancikova

Theses and Dissertations

In recent years the risks of emerging contaminants (ECs) have received substantial attention as potential environmental pollutants that persist in the environment due to their continual release. This research presents the work of three studies that provide critical insight into the spread of ECs, particularly antibiotic resistant bacteria derived from dairy manure and potentially harmful particles originated from nanomaterials in the soil-groundwater system. The adhesion of particles to mineral surfaces was quantified with the extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory that includes Lifshitz-van der Waals, Lewis acid-base, electrostatic double layer and steric repulsion interactions. The transport of ECs was conducted in column …

Simulating Recharge In A Wisconsin Watershed: The Effect Of Sub Annual Precipitation Patterns, Alice Egan

Theses and Dissertations

A watershed, the Prairie River in north-central Wisconsin was used to analyze why the same annual precipitation generates variable annual recharge rates. Global Climate Models (GCMs) with three greenhouse gas emission scenarios (B1, A1B and A2) for two time series 2047-2065 and 2082-2100 were used to examine the annual and monthly differences between the Prairie River watershed future projections and the Prairie River watershed historical record, 1954-2009. The USGS soil water balance (SWB) model was used to calculate recharge.

In the Prairie River watershed, there is a strong correlation (R²=0.84) between growing season recharge and growing season precipitation, and there …
