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.

Hydrogeologic mapping and three-dimensional geologic modeling of glacial deposits in a multicounty area of southeastern Michigan, northeastern Indiana, and northwestern Ohio Hydrogeologic mapping and three-dimensional geologic modeling of glacial deposits in a multicounty area of southeastern Michigan, northeastern Indiana, and northwestern Ohio
The glacial deposits underlying southeastern Michigan, northeastern Indiana, and northwestern Ohio are a substantial source of water to communities, agriculture, and industry in the region. Previous efforts to characterize aquifer materials in the area cited a need for additional information about the underlying hydrogeologic characteristics and related groundwater availability as well...
Potential water-quality and hydrology stressors on freshwater mussels with development of environmental DNA assays for selected mussels and macroinvertebrates in Big Darby Creek Basin, Ohio, 2020–22 Potential water-quality and hydrology stressors on freshwater mussels with development of environmental DNA assays for selected mussels and macroinvertebrates in Big Darby Creek Basin, Ohio, 2020–22
The richness and abundance of freshwater mussels in the Big Darby Creek Basin has declined in recent decades, according to survey results published by the Ohio Biological Survey. In October 2016, a major mussel die-off of undetermined cause reportedly affected over 50 miles of Big Darby Creek; however, fishes and other wildlife were not noticeably impacted. Pollution, habitat destruction...
Road salt collection and redistribution at an urban rain garden on sandy soil, Gary, Indiana Road salt collection and redistribution at an urban rain garden on sandy soil, Gary, Indiana
Rain gardens installed as green infrastructure to divert storm runoff from entering combined sewers also collect dissolved constituents and particulates. An urban rain garden in northwestern Indiana, USA, was continuously monitored from November 2019 to May 2021 to evaluate the fate of dissolved constituents entering the rain garden in runoff. Physical and chemical properties of soils in...

Wings of Change: The Environment's Influence on Bird Flu
Low pathogenic avian influenza (LPAI) viruses naturally occur in wild birds and are rarely fatal. Highly pathogenic avian influenza (HPAI) viruses are highly contagious, spread rapidly, are often fatal to poultry, and have been responsible for worldwide outbreaks. Together, LPAI and HPAI are generally referred to as either avian influenza viruses (AIVs) or "the bird flu."
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...
