Per- and polyfluoroalkyl substances (PFAS) in United States tapwater: Comparison of underserved private-well and public-supply exposures and associated health implications
Tapwater from 716 locations (269 private-wells; 447 public supply) across the US was collected during 2016–2021 including three locations where temporal sampling was conducted. Seventeen PFAS were observed at least once.

Ohio-Kentucky-Indiana Water Science Center
Welcome to the Ohio-Kentucky-Indiana Water Science Center (OKI WSC) webpage! We work closely with our local, state, federal, and tribal partners to provide unbiased and timely water resource information on streamflow, water quality, water-use, and groundwater data to resource managers and the public. Our Center includes the key water resources of the Ohio River, Lake Erie, and Lake Michigan.

Prioritizing US Geological Survey science on salinization and salinity in candidate and selected priority river basins
The US Geological Survey (USGS) is selecting and prioritizing basins, known as Integrated Water Science basins, for monitoring and intensive study. Previous efforts to aid in this selection process include a scientifically defensible and quantitative assessment of basins facing human-caused water resource challenges (Van Metre et al. in Environmental Monitoring and Assessment, 192(7)...
Flood-inundation maps for the Cuyahoga River in and near Independence, Ohio, 2024
Digital flood-inundation maps for a 9.9-mile reach of the Cuyahoga River in and near Independence, Ohio, were created by the U.S. Geological Survey (USGS) in cooperation with the Northeast Ohio Regional Sewer District Board of Trustees. Water-surface profiles were computed for the stream reach by using a one-dimensional steady-state step-backwater model. The model was calibrated to the...
Flood-inundation maps for the Cuyahoga River at Jaite, Ohio, 2024
Digital flood-inundation maps for a nearly 6-mile reach of the Cuyahoga River at Jaite, Ohio, were created by the U.S. Geological Survey (USGS) in cooperation with the Northeast Ohio Regional Sewer District Board of Trustees. The maps depict estimates of the extent and depth of flooding corresponding to selected water levels (stages) at USGS streamgage 04206425 on the Cuyahoga River at...

Groundwater Age Estimates, Groundwater Quality, and Hydrogeologic Characteristics of Chase Street Flowing Well and Similar Confined Wells, Little Calumet River Basin, Indiana
In cooperation with The Little Calumet River Basin Development Commission and the Urban Waters Federal Partnership The Little Calumet River Basin Development Commission (LCRBDC) is developing a park around a local cultural landmark, known locally as the Chase Street flowing well, in Gary, Indiana, a community in the Urban Waters Federal Partnership--Northwest Indiana Area. Groundwater from the...
Assessing stormwater reduction through green infrastructure: RecoveryPark (Detroit, Mich.)
The effectiveness of green infrastructure (including urban land conversion and bioswales) at reducing stormwater runoff is being assessed at RecoveryPark, a redeveloped urban farm in Detroit, Michigan. This study will monitor pre- and post-construction storm-sewer flow, groundwater levels, precipitation, and potential evapotranspiration (ET) to evaluate stormwater-volume reduction in response to...
Assessing stormwater reduction using green infrastructure: Gary City Hall (Gary, Ind.)
The effectiveness of green infrastructure (rain gardens and decreased impervious surface) at reducing stormwater runoff and capturing dissolved chloride is being assessed at a redevelopment project at Gary City Hall (Gary, Indiana). This study will evaluate pre- and post-construction hydrologic conditions using data collected by monitoring storm-sewer flow, groundwater levels, soil moisture, and...
