Selenium Removal By Sediments And Plants At The Constructed Pariette Wetlands, Utah (Usa), Colleen P. Jones, Michael Amacher, Paul R. Grossl, Astrid R. Jacobson

Plants, Soils, and Climate Faculty Publications

Selenium (Se) contamination of public lands and water is a result of irrigated agriculture and mining activities in areas rich in Se geologic deposits. Pariette Draw is part of the northern Colorado Plateau and is an area of concern for Se contamination in the Pariette Wetlands. Pariette Wetlands, a wetland built in the 1970s to provide wildlife habitat, is distinguished by its arid climate and a short growing season of hot dry summers followed by cold winters with several months below freezing. An understanding of how Se is mobilized and removed within the wetland will provide management strategies that minimize …

Evaluation Of Hydrograph Separation Techniques With Uncertain End-Member Composition, Eileen Page Lukens, Bethany T. Neilson, Kenneth H. Williams, Janice Brahney

Watershed Sciences Faculty Publications

Hydrograph separation is one of many approaches used to analyse shifts in source water contributions to stream flow resulting from climate change in remote watersheds. Understanding these shifts is vital, as shifts in source water contributions to a stream can shape water management decisions. Because remote watersheds are often inaccessible and have poorly characterized contributing water sources, or end-members, it is critical to understand the implications of using different hydrograph separation techniques in these data-limited environments. To explore the uncertainty associated with different techniques, results from two hydrograph separation techniques, mass balance and principle component analysis, were compared using 3 …

Environmental Insights From A Utah Pilot Study On Well-Being, Casey Trout

Research on Capitol Hill

This project focuses on the importance of the natural environment to the well-being of those surveyed during a 2018 pilot study. The pilot study marked the beginning of the Utah Well-being Project, a 5-year study to assess well-being across Utah communities.

The survey asked participants questions about their overall well-being and their well-being in relation to twelve commonly articulated “domains”, including those that are listed in Figures 1 and 2.

Residents' Annoyance Responses To Aircraft Noise Events, United States, National Aeronautics And Space Administration

Transportation

In a study conducted in the vicinity of Salt Lake City International Airport, community residents reported their annoyance with individual aircraft flyovers during rating sessions conducted in their homes. Annoyance ratings were obtained at different times of the day. Aircraft noise levels were measured, and other characteristics of the aircraft were noted by trained observers. Metrics commonly used for assessing aircraft noise were compared, but none performed significantly better than A-weighted sound pressure level. A significant difference was found between the ratings of commercial jet aircraft and general aviation propeller aircraft, with the latter being judged less annoying. After the …

Geophysical Surveys For Buried Waste Detection At The Idaho National Engineering Laboratory, U.S. Department Of Energy

All U.S. Government Documents (Utah Regional Depository)

This report describes a series of geophysical surveys performed at the Idaho National Engineering Laboratory (INEL). The main purpose of the surveys was to evaluate techniques, principally ground-penetrating radar, for detecting and mapping radioactive wastes buried in shallow trenches and pits.
