Data

Phosphorus, nitrogen, chloride, and suspended-sediment loads, in 24 U.S. tributaries of the Great Lakes, were estimated using U.S. Geological Survey (USGS) data from the Great Lakes Restoration Initiative (GLRI) monitoring program for the period Oct 2010 through Sept 2023 (USGS water years 2011-23). Specific water-quality constituents include total phosphorus, orthophosphate, particulate...

This dataset presents mercury (Hg) and methylmercury (MeHg) concentration data in waters (surface river water and community drinking water), biota, plant, and sediments that were collected across eight communities along the Pra and Ankobra Rivers in Western Ghana. Water and sediment samples were collected in October 2024 from eight rivers along the Ankobra and Pra Rivers, two rivers...

This dataset describes mercury (Hg) and methylmercury (MeHg) concentration data and Hg and MeHg stable isotope values in plankton, waters, and sediments that were collected from two inland freshwater lakes in Madison, Wisconsin. Plankton and waters were collected monthly from May-October in 2021 and 2022 from Lake Mendota and Lake Monona and sediments were sampled in 2017. Samples were...

This release contains data collected to study surface-groundwater interactions during flood events in the floodplain of a restored reach of Underwood Creek in Wauwatosa, WI. Continuous floodplain sediment temperature data was collected at 6 sites from May 2018 to October 2021. Temperature data was used in conjunction with soil thermal property measurements and published groundwater...

The Sheboygan River Area of Concern (AOC) in Sheboygan County, Wisconsin, contains the lower 22 kilometers of the Sheboygan River, including the Wildwood Islands complex, and it is the focus of remediation and restoration efforts by federal, state, and local governmental entities. Local hydrogeomorphic data is often used to aid in remediation and restoration project design. This dataset...

The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bangor, Maine. The intention of this boresight is to provide an extensive array of high-accuracy ground control points for the...

This dataset consists of trace organic contaminant concentrations and bacteria counts in wastewater effluents, and observed responses in fish exposed to effluents. The study was conducted from April to September 2022 at a facility located in Hutchinson, Minnesota. Nine pairs of primary-treated, activated sludge secondary treated, and membrane bioreactor secondary treated wastewater were...

Private wells (n = 138) were sampled by large- and small-volume sampling methods in Grant, Iowa, and Lafayette Counties, Wisconsin, USA in 2019 and 2020. Well water samples were analyzed for microorganisms by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Gene targets for viruses, bacteria, and protozoa were analyzed, including...

This dataset contains information from groundwater monitoring wells at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. The information includes field and laboratory methods, site locations, and inorganic and organic chemistry data. Samples were collected between 2009 and 2023, and analyzed for inorganic anions: F (fluoride), Cl...

This dataset describes mercury (Hg) concentrations and methylation rate potentials that were measured in Lake Mendota, Wisconsin, US in 2020 and 2021. This work is a collaboration between the University of Wisconsin, University of California-Davis, and the U.S. Geological Survey. Samples were collected to examine the linkages between Hg methylation, biogeochemical conditions, and...

This data release describes water service areas (WSA) for community water systems (CWS) within the conterminous United States, representing areas of active service between 2010 and 2020. A WSA is defined by a delineated polygon that contains all customers served by a water system. WSAs are represented by an ArcGIS shapefile. The U.S. Safe Drinking Water Act defines a CWS as a type of...

This data release contains 2 shapefiles which include 626 unique shorelines and 3 foredune toes spanning 2016 to 2023 along Minnesota Point, a 9-kilometer long bay-mouth bar at the western end of Lake Superior. Each shoreline represents the intersection line between land and water at a unique time associated with the capture of a satellite image, and these shorelines are used to examine...
