Environmental Site Assessment And Hydrogeologic Impacts To Groundwater At St. Ignatius, Montana And Hanford, Washington, Ryan M. Carter
Environmental Site Assessment And Hydrogeologic Impacts To Groundwater At St. Ignatius, Montana And Hanford, Washington, Ryan M. Carter
Graduate Student Theses, Dissertations, & Professional Papers
The following Environmental Studies Master’s Portfolio is a compilation of works completed individually and with peers in order to fulfill requirements for the Master of Science degree. These works demonstrate range, depth, and the interdisciplinary nature of the course of study. As an undergraduate student at Eastern Washington University, I studied Environmental Science with a concentration in hydrogeology. I was interested in learning about the natural world and wanted to develop a deeper connection to it. Inevitably, I was exposed to courses that examined the causes and effects of hazardous waste site remediation, and this topic became my passion. The …
Adapting Near-Ultraviolet Colorimetry For Long-Term In Situ Monitoring Of Hexavalent Chromium In Groundwater Aquifers, Janine Carter
Adapting Near-Ultraviolet Colorimetry For Long-Term In Situ Monitoring Of Hexavalent Chromium In Groundwater Aquifers, Janine Carter
Graduate Student Theses, Dissertations, & Professional Papers
This paper briefly describes sources of hexavalent chromium [Cr(VI)] and the risk it poses to human health and the environment; current methods used to regulate, monitor, and measure Cr(VI); the basic design of a submersible, direct-reading sensor in development for long-term monitoring of Cr(VI) concentration in natural waters; and the means developed to correct sensor readings for two common analytical interferences, turbidity and pH, that could lead to an incorrect measurement of Cr(VI). The principal purposes of this study are to analyze the current methods used to compensate for sample turbidity, to develop methods to compensate for sample pH, and …
