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'm also a member of the Water Quality Integration and Liaison Support (QWILS) Advisory Team, where I serve as the final arbiter for the NWIS parameter and method code reference dictionaries. In addition, I serve as the lab manager in Lakewood as well as analyze Rocky Mountain Snowpack Chemistry Monitoring samples in the summertime.

Natural 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 system
Mobilization 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 te
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
