Austin K Baldwin
Austin Baldwin is a Research Hydrologist with the USGS Idaho Water Science Center in Boise, Idaho.
Austin's research focuses on field-based studies of contaminants in surface water and sediment, including organic compounds, mercury and other metals, and microplastics. His work specifically focuses on (1) investigations into the sources, transport, and fate of contaminants, (2) processes driving contaminant partitioning among environmental compartments and transformation to more bioavailable forms, and (3) potential adverse effects of contaminants on ecosystem health. Through each of these research themes, he aims to inform management decisions to improve ecosystem health.
RESEARCH INTERESTS
Organic contaminants in aquatic environments; mercury in aquatic environments; aquatic toxicity; microplastic sources, transport, fate, and biological uptake; polycyclic aromatic hydrocarbon source identification.

Plastic debris in 29 Great Lakes tributaries: Relations to watershed attributes and hydrology
Plastic debris is a growing contaminant of concern in freshwater environments, yet sources, transport, and fate remain unclear. This study characterized the quantity and morphology of floating micro- and macroplastics in 29 Great Lakes tributaries in six states under different land covers, wastewater effluent contributions, population densities, and hydrologic conditions. Tributaries were sampledAuthorsAustin K. Baldwin, Steven R. Corsi, Sherri A. MasonOrganic contaminants in Great Lakes tributaries: Prevalence and potential aquatic toxicity
Organic compounds used in agriculture, industry, and households make their way into surface waters through runoff, leaking septic-conveyance systems, regulated and unregulated discharges, and combined sewer overflows, among other sources. Concentrations of these organic waste compounds (OWCs) in some Great Lakes tributaries indicate a high potential for adverse impacts on aquatic organisms. DuringAuthorsAustin K. Baldwin, Steven R. Corsi, Laura A. De Cicco, Peter L. Lenaker, Michelle A. Lutz, Daniel J. Sullivan, Kevin D. RichardsOrganic waste compounds as contaminants in Milwaukee-area streams
Organic waste compounds (OWCs) are ingredients and by-products of common agricultural, industrial, and household substances that can contaminate our streams through sources like urban runoff, sewage overflows, and leaking septic systems. To better understand how OWCs are affecting Milwaukee-area streams, the U.S. Geological Survey, in cooperation with the Milwaukee Metropolitan Sewerage District,AuthorsAustin K. Baldwin, Steven R. Corsi, Christopher Magruder, Matthew Magruder, Jennifer L. BruceHuman and bovine viruses in the Milwaukee River Watershed: hydrologically relevant representation and relations with environmental variables
To examine the occurrence, hydrologic variability, and seasonal variability of human and bovine viruses in surface water, three stream locations were monitored in the Milwaukee River watershed in Wisconsin, USA, from February 2007 through June 2008. Monitoring sites included an urban subwatershed, a rural subwatershed, and the Milwaukee River at the mouth. To collect samples that characterize variAuthorsSteven R. Corsi, M. A. Borchardt, S. K.

In 2008, the U.S. Geological Survey and the Milwaukee Metropolitan Sewerage District initiated a study to develop regression models to estimate real-time concentrations and loads of chloride, suspended solids, phosphorus, and bacteria in streams near Milwaukee, Wisconsin. To collect monitoring data for calibration of models, water-quality sensors and automated samplers were installed at six sitesAuthorsAustin K. Baldwin, Dale M. Robertson, David A.

An assessment of organic chemicals and aquatic toxicity in streams located near Milwaukee, Wisconsin, indicated high potential for adverse impacts on aquatic organisms that could be related to organic waste compounds (OWCs).

The Menomonee River drainage basin in southeast Wisconsin is undergoing changes that may affect water quality. Several rehabilitation and flood-management projects are underway, including removal of concrete channels and the construction of floodwater retention basins. The city of Waukesha may begin discharging treated wastewater into Underwood Creek, thus approximately doubling the current base-fAuthorsAustin K. Baldwin, David J. Graczyk, Dale M.
