Laura Hubbard is a Research Hydrologist with the Upper Midwest Water Science Center and the co-lead of the Food Resources Integrated Science Team within the Ecosystems Mission Area Environmental Health Program.
Laura Hubbard earned a B.S. in Geological Sciences from the University of Wisconsin and an M.S. in Earth Sciences (Hydrology) from Indiana University. She began her career at the USGS as a student trainee assisting urban non-point and rural edge-of-field runoff projects. Beginning in 2007, she led projects examining nutrient retention in restored and native oxbow wetlands. Shortly after she began working on projects focused on contaminants of emerging concern, including characterizing chemical and microbial contaminants from animal feeding operations and the hydrological, chemical, and biological effects of eliminating a wastewater treatment facility discharge from an urban stream ecosystem. As a co-lead of the Food Resources Integrated Science Team within the USGS Ecosystems Mission Area, she has led and coordinated national studies investigating agricultural and urban contaminants in groundwater, surface water, and plant and animal tissue including viruses, bacteria, pathogens, per- and polyfluoroalkyl substances, disinfection by-products, pesticides, and pharmaceuticals.

Contaminant exposure and transport from three potential reuse waters within a single watershed
Global demand for safe and sustainable water supplies necessitates a better understanding of contaminant exposures in potential reuse waters. In this study, we compared exposures and load contributions to surface water from the discharge of three reuse waters (wastewater effluent, urban stormwater, and agricultural runoff).

Process wastewaters from food, beverage, and feedstock facilities, although regulated, are an under-investigated environmental contaminant source. Food process wastewaters (FPWWs) from 23 facilities in 17 U.S. states were sampled and documented for a plethora of chemical and microbial contaminants. Of the 576 analyzed organics, 184 (32%) were detected at least once, with concentrations as large asByEcosystems, Water Resources, Contaminant Biology, Environmental Health Program, Toxic Substances Hydrology, Central Midwest Water Science Center, Kansas Water Science Center, New Jersey Water Science Center, Pennsylvania Water Science Center, South Atlantic Water Science Center (SAWSC), Upper Midwest Water Science Center, National Water Quality LaboratoryA comprehensive statewide spatiotemporal stream assessment of per- and polyfluoroalkyl substances (PFAS) in an agricultural region of the United States

Evidence for interannual persistence of infectious influenza A viruses in Alaska wetlands
Influenza A viruses (IAVs) deposited by wild birds into the environment may lead to sporadic mortality events and economically costly outbreaks among domestic birds. There is a paucity of information, however, regarding the persistence of infectious IAVs within the environment following deposition. In this investigation, we assessed the persistence of 12 IAVs that were present in the cloaca and/orExposure and transport of alkaloids and phytoestrogens from soybeans to agricultural soils and streams in the Midwestern United States
Phytotoxins are naturally produced toxins with potencies similar/higher than many anthropogenic micropollutants. Nevertheless, little is known regarding their environmental fate and off-field transport to streams. To fill this research gap, a network of six basins in the Midwestern United States with substantial soybean production was selected for the study.

Manure from livestock production has been associated with the contamination of water resources. To date, research has primarily focused on runoff of these contaminants from animal operations into surface water, and the introduction of poultry-derived pathogenic zoonoses and other contaminants into groundwater is under-investigated. We characterized pathogens and other microbial and chemical contamA surrogate regression approach for computing continuous loads for the tributary nutrient and sediment monitoring program on the Great Lakes
Water quality (WQ) in many Great Lake tributaries has been degraded (increased nutrient and sediment concentrations) due to changes in their watersheds, resulting in downstream eutrophication. As part of the Great Lakes Water Quality Agreement, specific goals were established for loading of specific constituents (e.g., phosphorus). In 2010, the Great Lakes Restoration Initiative was launched to idHighlighting the complexities of a groundwater pilot study during an avian influenza outbreak: Methods, lessons learned, and select contaminant results
The highly pathogenic avian influenza (H5N2) outbreak in the Midwestern United States (US) in 2015 was historic due to the number of birds and poultry operations impacted and the corresponding economic loss to the poultry industry and was the largest animal health emergency in US history. The U.S. Geological Survey (USGS), with the assistance of several state and federal agencies, aided the responAvian influenza virus RNA in groundwater wells supplying poultry farms affected by the 2015 influenza outbreak
During the 2015 outbreak of highly pathogenic avian influenza virus (HPAI) on poultry farms in the midwestern United States, concern was raised about the potential for HPAI to contaminate groundwater. Our study objective was to evaluate the occurrence of HPAI in the groundwater supply wells on 13 outbreak-affected poultry farms in Iowa and Wisconsin. We sampled 20 wells, six waste-storage lagoons,Flood-frequency characteristics of Wisconsin streams
Flood-frequency characteristics for 360 gaged sites on unregulated rural streams in Wisconsin are presented for percent annual exceedance probabilities ranging from 0.2 to 50 using a statewide skewness map developed for this report. Equations of the relations between flood-frequency and drainage-basin characteristics were developed by multiple-regression analyses.

The use of oxbow wetlands has been identified as a potential strategy to reduce nutrient transport from agricultural drainage tiles to streams in Iowa. In 2013 and 2014, a study was conducted in north-central Iowa in a native oxbow in the Lyons Creek watershed and two restored oxbow wetlands in the Prairie Creek watershed (Smeltzer west and Smeltzer east) to assess their effectiveness at reducingU.S. Geological Survey science strategy for highly pathogenic avian influenza in wildlife and the environment (2016–2020)
