Science and Products
Food Resources Science Team
The team studies the movement of toxicants and pathogens associated with food production through watersheds and aquifers, to water resources where exposure can occur. That information is used to understand if there are adverse effects upon exposure and to develop decision tools to protect health.
Occurrence of Avian Influenza Virus in Groundwater—Study Provides Baseline Data and Informs Future Studies
This pilot study provided baseline data on avian influenza virus (AIV) occurrence in groundwater underlying poultry farms and documented the challenges for conducting a pathogen transport study during a disease outbreak.
Recovery of Stream and Adjacent Groundwater After Wastewater Treatment Facility Closure
The hydrology and chemistry of a wastewater-impacted stream and adjacent groundwater responded rapidly (had fewer chemicals at lower concentrations) following wastewater treatment facility shutdown. However, the adjacent shallow groundwater remained a continuing source of some wastewater-derived contaminants to the stream at least 1 year post-shutdown.
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...

Exposure 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...
Hama, J. R.; Kolpin, Dana W.; LeFevre, G. H.; Hubbard, Laura E.; Powers, M. M.; Strobel, B. W. Poultry litter as potential source of pathogens and other contaminants in groundwater and surface water proximal to large-scale confined poultry feeding operations
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...
Hubbard, Laura E.; Givens, Carrie E.; Griffin, Dale W.; Iwanowicz, Luke; Meyer, Michael T.; Kolpin, Dana W. A 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.,...
Robertson, Dale M.; Hubbard, Laura E.; Lorenz, David L.; Sullivan, Daniel J. Highlighting 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...
Hubbard, Laura E.; Kolpin, Dana W.; Fields, Chad L. ; Hladik, Michelle L.; Iwanowicz, Luke R. Avian 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...

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-...
Walker, John F.; Peppler, Marie C.; Danz, Mari E.; Hubbard, Laura E. The effect of restored and native oxbows on hydraulic loads of nutrients and stream water quality
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...

U.S. Geological Survey science strategy for highly pathogenic avian influenza in wildlife and the environment (2016–2020)
IntroductionThrough the Science Strategy for Highly Pathogenic Avian Influenza (HPAI) in Wildlife and the Environment, the USGS will assess avian influenza (AI) dynamics in an ecological context to inform decisions made by resource managers and policymakers from the local to national level. Through collection of unbiased scientific information on...

Understanding the hydrologic impacts of wastewater treatment plant discharge to shallow groundwater: Before and after plant shutdown
Effluent-impacted surface water has the potential to transport not only water, but wastewater-derived contaminants to shallow groundwater systems. To better understand the effects of effluent discharge on in-stream and near-stream hydrologic conditions in wastewater-impacted systems, water-level changes were monitored in hyporheic-zone and shallow...
Hubbard, Laura E.; Keefe, Steffanie H.; Kolpin, Dana W.; Barber, Larry B.; Duris, Joseph W.; Hutchinson, Kasey J.; Bradley, Paul M. Pre/post-closure assessment of groundwater pharmaceutical fate in a wastewater‑facility-impacted stream reach
Pharmaceutical contamination of contiguous groundwater is a substantial concern in wastewater-impacted streams, due to ubiquity in effluent, high aqueous mobility, designed bioactivity, and to effluent-driven hydraulic gradients. Wastewater treatment facility (WWTF) closures are rare environmental remediation events; offering unique insights into...

Dairy-impacted wastewater is a source of iodinated disinfection byproducts in the environment
Iodinated disinfection byproducts (DBPs) are among the most toxic DBPs, but they are not typically measured in treated water. Iodinated DBPs can be toxic to humans, and they also have the potential to affect aquatic communities. Because of the specific use of iodine and iodine-containing compounds in dairies, such livestock operations can be a...
