Water-quality data were collected by the Providence Water Supply Board (PWSB) from tributaries in the Scituate Reservoir drainage area, October 1, 2017 through September 30, 2022 (water years 2018 through 2022). Water-quality samples were collected by the PWSB either monthly or quarterly at fixed stations on 38 tributaries in the Scituate Reservoir drainage area, Rhode Island. These data were used to calculate instantaneous loads and yields of constituents in reports by the U.S. Geological Survey. Water-quality samples were collected following a strict sampling schedule so that water-quality samples would be representative of various weather conditions. Samples were analyzed at the PWSB water-quality laboratory...
Chemical and microbiological results, quality assurance and quality control, site location, and method information for surface water, bed sediment, and wastewater effluent collected from 34 stream locations across Iowa (United States). Environmental samples were analyzed for a suite of 29 antibiotics, plated on selective media for 15 types of bacteria growth, and DNA was extracted from culture growth and used in downstream polymerase chain reaction (PCR) assays for the detection of 24 antibiotic resistance genes. Environmental field data were collected in-situ for water temperature (°C), specific conductivity (µs/cm), dissolved oxygen (mg/L), pH (standard units), and turbidity (FNU) using a multiparameter sonde...

This study evaluated the use of medicated feeds to treat furunculosis infections caused by the bacterium Aeromonas salmonicida in lake herring (Coregonus artedi, Lesueur, 1818). The objectives of this two-phase study were to (1) determine if Coregonus artedi could be adequately and consistently infected with A. salmonicida by the methods of bath immersion or intraperitoneal (IP) injection, and (2) determine if the medicated feeds Oxytetracycline Dihydrate (Terramycin® 200 For Fish) and Florfenicol (Aquaflor®) could be used for the control of furunculosis caused by A. salmonicida. These datasets include water quality, mortality, feed weights and behavior, and qPCR data collected during both phases of the study.
The United States Geological Survey’s (USGS) New Jersey Water Science Center, in coordination with the Delaware River Basin Commission (DRBC) deployed a novel bacterial water-quality monitor, the Fluidion Alert V2 (Fluidion), in the Delaware River at Pyne Poynt Park in Camden County, New Jersey. Following United States Environmental Protection Agency (EPA) recreational water quality criteria, DRBC has been evaluating fecal indicator bacteria (FIB) abundance along Lower Delaware River at Pyne Poynt Park in support of primary use recreation (DRBC, 2022). The EPA recreation criteria establish acceptable levels of FIB abundance for primary contact recreation, such as swimming, and secondary contact recreation, such...

FIB monitoring,
This data set contains continuous water-surface elevation and water-quality (temperature, specific conductance, salinity, and turbidity) data recorded at 6- and 15-minute intervals, respectively, from two sites in the Bronx on the Harlem River -- Roberto Clemente State Park and Mill Pond Park. Water elevation was monitored every second to detect changes indicative of boat wakes expected to resuspend bed sediment from nearby alcoves. Boat wake detection triggered the collection of 1-second interval water elevation and 1-minute interval turbidity data. In addition to continuous data, grab samples for fecal indicator bacteria (Enterococci) and total suspended solids were collected weekly from - March to September,...

A National Park Service Partnership Program project was conducted in 2017 - 2019 on water quality parameters up-stream and downstream of a confined animal feeding operation on a Buffalo National River tributary (Big Creek). Monthly, over a period of 20 months, patterns of nutrients in water (nitrogen and phosphorus), periphyton (chlorophyll a and algal assemblages), and bacterial responses (viable bacterial densities, total bacterial counts, and live bacterial metabolic activity) were measured at six sites along Buffalo National River. Heterotrophic bacteria were concentrated from the water samples. The metabolic activity of heterotrophic bacteria was determined by fluorescent staining of enzyme (esterase) activity...

We investigated the cultureable bacterial communities in the native freshwater mussel faunal in the Clinch River, VA/TN during mussel mortality events in 2018, 2019 and 2020 and examine the spatial and temporal distribution of bacterial genera among Pheasantshells and six other unionid species.

FY2017The Integrated Rangeland Fire Management Strategy Actionable Science Plan places a high priority on assessing control measures for invasive annual grasses, which provide fuel for rangeland fire and impede restoration of desirable perennials. Weed-suppressive strains of the bacterium Psuedomonas fluoresens (P.f.) are an emerging but yet untested tool for selectively reducing these annual grasses. P.f. may suppress annuals for approximately 2-5 years, bridging the short-term action of herbicides and long-term resistance provided as native bunchgrasses recover. In 2015-2016, the USGS responded to a request from the Idaho sage grouse action group to establish a series of field-based experiments to assess the efficacy...
