Remobilization Of Cobalt, Copper, Nickel, Lead, And Zinc In A Riparian Wetland Model, Richard Glenn Dolly

Electronic Theses and Dissertations

The mobility of chemically persistent metals in riparian wetland systems that could have a detrimental impact on the environment is an area of active research. This study utilized a physical model consisting of open water and wetland cells designed to simulate a natural riparian wetland to examine the mobility of five metals. The objective of the study was to determine if riparian wetlands have the potential to serve as permanent sinks for metals, or if they only serve as temporary sinks and with time metals could be remobilized and released. Specifically, this study examined the long-term behavior of Co, Cu, …

Utilizing Indicator Of Reduction In Soils Tubes To Affirm A Serpentinitic Hydric Soil On The California Central Coast, Jason Demoss

Natural Resources Management and Environmental Sciences

Wetlands are vital ecosystems that are crucial in maintaining the life of rare and unique soils, plants, and animals. These ecosystems are key players in water storage, water filtration, carbon storage, and harboring unique species. Since the intervention of human development on the Earth’s surface, almost 50% of the Earth’s original wetlands have either been damaged or destroyed. The identification and assessment of both new and old wetlands is crucial in the survival of these precious ecosystems and their conservation. A 3 month-long study was performed to confirm the hydric status of a soil derived from serpentinitic parent material. The …

Effects Of Road Salt On Asylum Lake Geochemistry, Davina A. Wyman

Masters Theses

Several studies indicate that seasonal applications of road deicers can lead to saline runoff entering surface water and groundwater, which can in turn change the chemistry, density, and physical mixing patterns of urban lakes. An investigation at Asylum Lake, an urban lake located near three major roadways, was conducted to determine the degree of road salt contamination in the lake, to determine if salt loading disrupts seasonal mixing patterns, and to determine the extent of redox stratification present due to eutrophic conditions. Samples were collected monthly from the deepest point in Asylum Lake over a 19-month period and analyzed for …

Groundwater Quality Assessment From Domestic Water Wells In The Fayetteville Shale Gas Play Area In Central Arkansas, Anna Marie Nottmeier

Graduate Theses and Dissertations

This study establishes a spatially distributed domestic water well groundwater quality data set, throughout the Fayetteville Shale Gas Play (FSGP) in central Arkansas. The data set facilitates characterization of the geology and groundwater quality across the study area, benefits residents who may have concerns about the potential impacts on their well water quality, and provides a groundwater quality basis to which complaints can be compared and resolved. The assessment included: research of the study area, site reconnaissance, water sampling and collection, interviews with owners of the property, analytical analysis, Quality Assurance and Quality Control, and groundwater data interpretation.

The study …
