Abby L Keith
Abby is a Chemist and Local Database Manager (LDM) for the USGS Colorado Water Science Center (COWSC) in Lakewood, CO. She also supports the USGS Water Mission Area as a National Water Information System (NWIS) Structure Data Support Specialist.
As an LDM for Colorado data users, I provide moral and technical support in all things NWIS - including database tools, workflows and best practices. I also support the COWSC by serving as the lab manager in Lakewood and analyze our Rocky Mountain Snowpack Chemistry Monitoring samples each summer. I support the Water Mission Area by overseeing the operations in Colorado for the National Water Quality Network (NWQN) as well as a few select sites across the Western U.S. which were formerly part of the Hydrologic Benchmark Network. I'm also a member of the Water Quality Integration and Liaison Support (QWILS) Advisory Team, where I serve as the final arbiter for the parameter and method code reference dictionaries for NWIS. In recent years, I have been involved with the modernization effort of our discrete database to AQ Samples as well as the NWIS reference list content known as the Reference List Management System (RLMS).

Rocky Mountain Regional Snowpack Chemistry Monitoring Study
Snowpacks collect atmospheric deposition throughout the snowfall season and offer a unique opportunity to obtain a composite sample of the chemistry of most of the annual precipitation at high elevations [> 1,800 meters]. The purpose of the snowpack network is to determine annual concentrations and depositional amounts of selected nutrients and other constituents in snow resulting from atmospheric... - Data
Geochemical data from batch experiments to test mobility of trace elements downgradient from breccia-pipe uranium deposits
This data release includes solid and aqueous chemical data related to a set of sequential laboratory batch experiments conducted to test and simulate the mobility of trace elements as natural waters contact ore from breccia pipe uranium (BPU) deposits located in northern Arizona. The experiments made use of aquifer-related, sedimentary rocks collected specifically for this study and archival ore m - Publications
Aquatic carbon export and dynamics in mountain headwater streams of the western U.S.
Mountain headwater streams actively cycle carbon, receiving it from terrestrial landscapes and exporting it through downstream transport and gas exchange with the atmosphere. Although their importance is now widely recognized, aquatic carbon fluxes in headwater streams remain poorly characterized. In this study, aquatic carbon fluxes were measured in 15 mountain headwater streams and were used inAuthorsDavid W. Clow, Garrett Alexander Akie, Robert G. Striegl, Colin Penn, Graham A. Sexstone, Gabrielle L. KeithNatural and anthropogenic geochemical tracers to investigate residence times and groundwater–surface-water interactions in an urban alluvial aquifer
A multi-component geochemical dataset was collected from groundwater and surface-water bodies associated with the urban Fountain Creek alluvial aquifer, Colorado, USA, to facilitate analysis of recharge sources, geochemical interactions, and groundwater-residence times. Results indicate that groundwater can be separated into three distinct geochemical zones based on location within the flow systemAuthorsConnor P. Newman, Suzanne Paschke, Gabrielle L. KeithMobilization of selenium from the Mancos Shale and associated soils in the lower Uncompahgre River Basin, Colorado
This study investigates processes controlling mobilization of selenium in the lower part of the Uncompahgre River Basin in western Colorado. Selenium occurs naturally in the underlying Mancos Shale and is leached to groundwater and surface water by limited natural runoff, agricultural and domestic irrigation, and leakage from irrigation canals. Soil and sediment samples from the study area were teAuthorsAlisa Mast, Taylor J. Mills, Suzanne S. Paschke, Gabrielle Keith, Joshua I. Linard
