Microbial and chemical contaminant occurrence and concentration in groundwater and surface water proximal to large-scale poultry facilities and poultry litter, 2016 Microbial and chemical contaminant occurrence and concentration in groundwater and surface water proximal to large-scale poultry facilities and poultry litter, 2016
Chemical and biological results, quality assurance and quality control, and method information from groundwater, surface water, and litter samples, collected from nine locations in Iowa and one in Wisconsin in 2016. Thirteen groundwater, nine surface water, four poultry litter, and four QA/QC samples were collected. Samples were analyzed at U.S. Geological Survey laboratories; bacteria...
Toxicity of potassium chloride, active compound in the molluscicide potash, on salmonid fishes and their forage base (Leetown Science Center, 2018). Toxicity of potassium chloride, active compound in the molluscicide potash, on salmonid fishes and their forage base (Leetown Science Center, 2018).
The data is supplemental to the 2018 USGS Open File Report, "An evaluation of the acute and chronic toxicity of potassium chloride, active compound in the molluscicide potash, on salmonid fishes and their forage base". This research was performed as a Science Support Partnership (SSP) study with USFWS in order to evaluate potential lethal and sublethal impacts of potassium chloride on...
Molecular detection of avian influenza virus from sediment samples in waterfowl habitats on the Delmarva Peninsula, USA Molecular detection of avian influenza virus from sediment samples in waterfowl habitats on the Delmarva Peninsula, USA
Data were collected as part of an investigation developed by Leetown Science Center to investigate the comparative detection of avian influenza viruses from waterfowl and potential environmental reservoirs such as aquatic sediment from waterfowl habitat. This dataset identifies positive or negative test results for qRT-PCR (quantitative reverse transcriptase polymerase chain reaction)...
Estrogen Equivalents of Surface Water in the Upper Chesapeake Bay Watershed (2008 - 2011) Estrogen Equivalents of Surface Water in the Upper Chesapeake Bay Watershed (2008 - 2011)
Intersex in small- and largemouth bass has been observed in the upper Chesapeake Bay Watershed since 2003. This observation is indicative of exposure to estrogenic endocrine disrupting chemicals. In order to complement biological data sets and better identify the spatial and temporal nature of this end-point, discrete grab water samples were collected throughout the upper Chesapeake Bay...
Chelonid Herpesvirus 5 (ChHV5) genomic sequences obtained through long-range PCR and high throughput sequencing from Florida and Hawaii green sea turtles with fibropapillomatosis Chelonid Herpesvirus 5 (ChHV5) genomic sequences obtained through long-range PCR and high throughput sequencing from Florida and Hawaii green sea turtles with fibropapillomatosis
The files in this data release are the processed DNA consensus sequence alignment files for the chelonid herpesvirus 5 (ChHV-5) genome plus 66 open reading frames representing protien-coding genes. DNA was extracted from tumor biopsies from green sea turtles (Chelonias mydas) with fibropapillomatosis sampled from Florida and Hawaii coastal waters. We used high-throughput short-read...
Analytical inorganic chemistry results for samples collected for the Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015 Analytical inorganic chemistry results for samples collected for the Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015
Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed the...

Pilot-scale expanded assessment of inorganic and organic tapwater exposures and predicted effects in Puerto Rico, USA Pilot-scale expanded assessment of inorganic and organic tapwater exposures and predicted effects in Puerto Rico, USA
A pilot-scale expanded target assessment of mixtures of inorganic and organic contaminants in point-of-consumption drinking water (tapwater, TW) was conducted in Puerto Rico (PR) to continue to inform TW exposures and corresponding estimations of cumulative human-health risks across the US. In August 2018, a spatial synoptic pilot assessment of than 524 organic, 37 inorganic, and select

Emerging investigator series: Municipal wastewater as a year-round point source of neonicotinoid insecticides that persist in an effluent-dominated stream Emerging investigator series: Municipal wastewater as a year-round point source of neonicotinoid insecticides that persist in an effluent-dominated stream
Neonicotinoids in aquatic systems have been predominantly associated with agriculture, but some are increasingly being linked to municipal wastewater. Thus, the aim of this work was to understand the municipal wastewater contribution to neonicotinoids in a representative, characterized effluent-dominated temperate-region stream. Our approach was to quantify the spatiotemporal...

Public and private tapwater: Comparative analysis of contaminant exposure and potential risk, Cape Cod, Massachusetts, USA Public and private tapwater: Comparative analysis of contaminant exposure and potential risk, Cape Cod, Massachusetts, USA
Background Humans are primary drivers of environmental contamination worldwide, including in drinking-water resources. In the United States (US), federal and state agencies regulate and monitor public-supply drinking water while private-supply monitoring is rare; the current lack of directly comparable information on contaminant-mixture exposures and risks between private- and public...

Genome sequences of 26 white sucker hepatitis B virus isolates from white sucker, catostomus commersonii, inhabiting transboundary waters from Alberta, Canada, to the Great Lakes, USA Genome sequences of 26 white sucker hepatitis B virus isolates from white sucker, catostomus commersonii, inhabiting transboundary waters from Alberta, Canada, to the Great Lakes, USA
We report 26 genomes of the white sucker hepatitis B virus (WSHBV) from the white sucker, Catostomus commersonii. Genome length ranged from 3541 to 3543 bp and nucleotide identity was 96.7% or greater across genomes. This work suggests a geographical range of this virus that minimally extends from the Athabasca River, Alberta, Canada to the Great Lakes, USA.

Production and characterization of a mouse monoclonal antibody against smallmouth bass (Micropterus dolomieu) IgM Production and characterization of a mouse monoclonal antibody against smallmouth bass (Micropterus dolomieu) IgM
A murine monoclonal antibody (mAb, IgG2a) was produced for the detection of smallmouth bass (Micropterus dolomieu) immunoglobulin (IgM). The antibody is specific for IgM heavy chain and was shown to also recognize the Ig heavy chain of largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) using Western Blot analysis of plasma from 9 teleost taxa. When applied to the...

Phylogeographic genetic diversity in the white sucker hepatitis B Virus across the Great Lakes Region and Alberta, Canada Phylogeographic genetic diversity in the white sucker hepatitis B Virus across the Great Lakes Region and Alberta, Canada
Hepatitis B viruses belong to a family of circular, double-stranded DNA viruses that infect a range of organisms, with host responses that vary from mild infection to chronic infection and cancer. The white sucker hepatitis B virus (WSHBV) was first described in the white sucker (Catostomus commersonii), a freshwater teleost, and belongs to the genus Parahepadnavirus. At present, the...
