My recent research focuses on understanding the occurrence, transport, and fate of nutrients, pesticides, and trace contaminants in hydrologic systems, and the drivers and influences of climate and human activities on water quality.

Biography

Anne Choquette is a hydrologist with the U.S. Geological Survey, Lower Mississippi-Gulf Water Science Center in Nashville, Tennessee.  She has worked in private industry, the National Park Service, and since 1982 has been with the U.S. Geological Survey in offices in Colorado, Kentucky, Florida, and Tennessee.  Past water research studies have spanned a range of topical areas including surface-water and groundwater quality; regional water-quality assessments; flood and low-flow frequency analyses; statistical modeling and trend analysis. Recent research has focused on understanding the occurrence, transport, & fate of nutrients, pesticides, and trace contaminants in hydrologic systems and the associated complex interactions and influences of climate, land use, and streamflow changes on water quality. Tangential interests include methodology and approaches to assess and strengthen evaluations of water-quality changes over time and to improve the design and efficacy of water-quality monitoring programs with the ultimate goal of providing guidance in sustainably utilizing land and water resources for long-term ecological and human needs.

Education

B.A. in Geology, University of North Carolina, Chapel Hill, North Carolina  (1973-1977)
M.S. in Watershed Sciences, California State University-Humboldt, Arcata, California (1980-1984)

  • 1987 – 2003: Project manager: USGS, Florida District and Florida Integrated Water Science Center, Tallahassee, FL.  Projects included a variety of hydrologic studies focused on stream and groundwater quality network design, and spatial and temporal assessments of water-quality data; low-flow characterization of Florida streams; hydrologic monitoring and water budget analysis of groundwater seepage lake.
  • 1985 – 1987: Project manager: USGS, Louisville, KY.  Statewide flood-frequency analyses and regionalization; water-quality field monitoring study in karst terrane; Design and implementation of USGS National Water Quality Assessment (NAWQA) Program surface-water pilot study in the Kentucky River basin (team).
  • 1983 – 1985: Hydrologist, USGS, Denver, CO.  Regional-scale streamflow, water quality, and trend analyses study of the Upper Colorado River basin in CO., WY., UT., NM., and AZ.
  • 1982 – 1983: Geologist, USGS, Denver, CO.  Geologic mapping and application of multiple geologic dating techniques focused on Quaternary history and sediment deposition in selected areas of Utah, Idaho, and Wyoming.
  • 1977 – 1982:  Positions included: geomorphologist (watershed rehabilitation) with National Park Service (Redwood National Park, Arcata, CA.); geologist (environmental geology) in consulting industry (Soil Testing Services, Inc., Research Triangle Park, N.C.); geologist (minerals exploration) in private industry (Chevron Resources Company, Denver, CO.).
