We deployed a sampler to characterize water quality from a household well tapping a shallow fractured dolomite aquifer in northeast Wisconsin. The sampler was deployed from January to May 2017, and monitored temperature, nitrate, chloride, specific conductance, and fluorescent dissolved organic matter on a minute time step; water was directed to sequential microbial filters during three...

Under the Great Lakes Restoration Initiative, the U.S. Geological Survey Mercury Research Lab (USGS MRL) conducted a multiyear assessment of mercury across the Laurentian Great Lakes. Biannual sampling was conducted across all five lakes onboard the U.S. Environmental Protection Agency (US EPA) research vessel Lake Guardian (in years 2010–2014, 2018) at pelagic sampling locations...

This data release contains input data and a model archive for a study that used particle image velocimetry to estimate the phosphorus load transported by floating surface material into Green Lake, Wisconsin from May 19 to October 31 of 2023 and 2024. It contains all raw input data and data processing code to reproduce results in the associated primary publication. Inputs to the model...

This data release provides phytoplankton environmental DNA (eDNA) data from 19 sites in 12 different streams within the Milwaukee Metropolitan Sewerage District Planning Area in and around Milwaukee, WI. These streams include the Milwaukee River, the Kinnickinnic River, the Menomonee River, and more. Phytoplankton composition was determined using eDNA sequencing techniques. Data were...

This data release provides tabulated geomorphic data from surveys for nine reaches along the Bad River and its tributaries the Marengo and Potato Rivers, ranging from 2003 to 2024. Included on this page is a tabulated inventory of all the data files (child items) and additional information associated with each reach. Child items are listed by their corresponding reach number. As data was...

This data release provides phytoplankton environmental DNA (eDNA), cyanotoxin biosynthesis gene abundance, phytoplankton microscopy, and cyanotoxin data collected from Ellsworth Rock Gardens in Kabetogama Lake at Voyageurs National Park (USGS site ID: USGS-482947092584401). These samples were collected three times, about every 12 hours, between September 17 and September 18, 2024...

The National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota is the site of a 1979 high-pressure crude oil pipeline rupture. Approximately 1.7 million liters of crude oil spilled onto the glacial outwash aquifer. After remediation and natural attenuation, an estimated 25% of the oil remains in the subsurface today. Groundwater monitoring at the site...

This data release documents performance testing of an experimental suspended‑sediment and water‑quality collapsible‑bag sampler with point‑ or depth‑integrating capabilities, the US XPD‑24‑200. Water samples were collected at known velocities in a controlled tow‑tank environment and during lake tows using multiple sampler‑nozzle sizes. For each test, tow velocity, sample volume, and...

This data release provides the input and output files, metadata, and R scripts used to apply a Structural Topic Model (STM) to public (local news articles) and scientific (abstracts) discourse on water quality in the Illinois River Basin (ILRB). A total of 6,822 local news articles published from 2018 through 2022, and 190 scientific abstracts published from 2018 through 2023 were...

These datasets includes physical and geochemical lab results of sediment samples collected from August 2017 to October 2018. Upland samples were collected at randomly selected sites in the watershed using the geographic information system (GIS) site-selection procedure. Three sets of passive suspended-sediment samplers were installed and sampled monthly. Streambank and streambed sediment...

These datasets includes physical and geochemical lab results of sediment samples collected from October 2016 to February 2018. Upland samples were collected at randomly selected sites in the watershed using the geographic information system (GIS) site-selection procedure. Passive suspended-sediment samplers were installed at three sites and sampled monthly. Streambank and streambed...

The East River is an agricultural tributary to the Lower Fox River and the Environmental Protection Agency (EPA) Green Bay Area of Concern (AOC) in northeast Wisconsin. This tributary has known excessive phosphorus (P) and suspended sediment loads that contribute to habitat related impairments and downstream algal blooms. As part of the Great Lakes Restoration Initiative (GLRI), the U.S
