Contrasting Seasonal Cycling Of Arsenic In A Series Of Subarctic Shield Lakes With Different Morphometric Properties, Jeremy Harbinson
Contrasting Seasonal Cycling Of Arsenic In A Series Of Subarctic Shield Lakes With Different Morphometric Properties, Jeremy Harbinson
Theses and Dissertations (Comprehensive)
The subarctic shield near Yellowknife, Northwest Territories (NWT), is populated with thousands of small lakes (<1.5 km2) and several large lakes. Historic mining activities in the region have left a legacy of environmental impacts and widespread arsenic (As) contamination in both aquatic and terrestrial environments. In particular, several small subarctic lakes near Yellowknife have been previously documented to be contaminated with high levels of As. Subarctic lakes are characterized by seasonal ice-cover that can persist for more than half of the year, yet little is known about the under-ice spatial and seasonal dynamics of As cycling. The objective of …1.5>
Landscape Materials: Impact On Water Quality At Different Temperatures, Vignesh Tiruvannamalai '24
Landscape Materials: Impact On Water Quality At Different Temperatures, Vignesh Tiruvannamalai '24
Distinguished Student Work
The purpose of this experiment is to analyze how commonly used landscaping materials (wood mulch, rubber mulch, and landscape stones) will affect the quality and chemical composition of runoff water they come into contact with, and how this will be impacted by different temperatures experienced in different climatic regions.
In order to conduct this experiment, always wear safety goggles and gloves when handling experiment materials. First, prepare the landscaping materials and rinse the containers and lids. Then, place the designated amount of landscaping materials in each container and fill each with 2.27 liters of filtered water, subsequently covering them and …

Groundwater Hydrogeolgy And Hydrochemistry Of Karst Springs In The Eastern Peninsula Of Fort Hood Military Installation, William Scribner Welles
Groundwater Hydrogeolgy And Hydrochemistry Of Karst Springs In The Eastern Peninsula Of Fort Hood Military Installation, William Scribner Welles
Electronic Theses and Dissertations
The eastern peninsula of Fort Hood Military Installation is underlain by a complex karst spring network. These springs are a primary water source in a protected habitat for endangered songbirds, which has only recently begun to be fully investigated. These Fredericksburg Group springs express both epigenetic and hypogenetic karst signatures. The study area is part of a paleo reef trend, a hydraulically disconnected segment of the northern section of the Edwards Aquifer. This study utilized standard ion index values, repeated measures, and principal component analyses on the chemical profiles of six perennial springs to classify spring water sources and their …

An Environmental Study Of The Origin, Distribution, And Bioaccumulation Of Selenium In Kentucky And Barkley Lakes, B. E. Mcclellan, Kenneth J. Frazer
An Environmental Study Of The Origin, Distribution, And Bioaccumulation Of Selenium In Kentucky And Barkley Lakes, B. E. Mcclellan, Kenneth J. Frazer
KWRRI Research Reports
Many samples of water, bottom sediment, and fish were analyzed for toxic metal ion content. The samples were collected from several selected sites along Kentucky and Barkley Lakes as well as the Cumberland River and several sub-impoundments along these aquatic systems. Emphasis was placed on selenium, although several other metal ions were determined. The results showed that there are no serious pollution problems with As, Cd, Cr, Cu, Hg, Pb, Se, Sr, Zn, or Zr at any of the sites examined. Actually, none of the trace metals examined even come close to the EPA limits on fish, with the exception …
