Sharon is a Physical Scientist with the USGS Colorado Water Science Center (COWSC), duty station Beaverton, Oregon.
Sharon received her masters from the University of Illinois in 1993 and has been both a Hydrologist and Physical Scientist with the U.S. Geological Survey since 1992. She has been a Geographic Information System (GIS) spatial analyst and database manager for multiple National and small programs and projects. She began her career in the Illinois Water Science Center with the Upper Illinois River Basin Pilot as part of the National Water-Quality Assessment Program (NAWQA). From there, she moved to the COWSC in 1993 to begin working with the South Platte NAWQA as a GIS analyst and database manager. She continued working with NAWQA in the COWSC on the High Plains NAWQA until 2010. After NAWQA, she worked with various National programs on water availability in the High Plains and Glacial aquifers and a national assessment of brackish water in aquifers of the United States. From 2018 to 2021, she again joined the NAWQA efforts working with the Regional Surface-Water Quality Assessment program. More recently, she has been working with various national efforts responsible for prioritizing watersheds for USGS research, determining post wildfire water-quality changes, and assisting in streamlining USGS workflows with respect to integrated science.

Data used to prioritize the selection of river basins for intensive monitoring and assessment by the U.S. Geological Survey
The U.S. Geological Survey (USGS) developed a systematic, quantitative approach to prioritize candidate basins that can support the assessment and forecasting objectives of the major USGS water science programs. Candidate basins were the level-4 hydrologic units (HUC4) with some of the smaller HUC4s being combined (hereafter referred to as modified HUC4 basins).

Metals and polycyclic aromatic hydrocarbons (PAHs) are common pollutants in urban streambed sediment, yet their occurrence is highly variable and difficult to predict.
