Bathymetric and velocimetric surveys at highway bridges crossing the Missouri River near Kansas City, Missouri, August 8–9, 2023 Bathymetric and velocimetric surveys at highway bridges crossing the Missouri River near Kansas City, Missouri, August 8–9, 2023
Bathymetric and velocimetric data were collected by the U.S. Geological Survey, in cooperation with the Missouri Department of Transportation, near 8 bridge crossings of the Missouri River near Kansas City, Missouri, on August 8–9, 2023. A multibeam echosounder mapping system was used to obtain channel- bed elevations for river reaches that extended about 1,550 to 1,640 feet...
Comparison of two precipitation gage networks in Cook County, Illinois Comparison of two precipitation gage networks in Cook County, Illinois
The Cook County Precipitation Network is a set of 25 precipitation gages established within Cook County, Illinois, on approximately a 5- to 7-mile square grid and used by the U.S. Army Corps of Engineers to help account for diversions of water from Lake Michigan to the State of Illinois. The transition from the precipitation gage network operated by the Illinois State Water Survey to the
Performance evaluation and methods comparison of transcriptomic-based approaches for the characterization of wastewater treatment effluent Performance evaluation and methods comparison of transcriptomic-based approaches for the characterization of wastewater treatment effluent
Wastewater treatment effluents (WWTE) present complex risks to aquatic ecosystems that are difficult to characterize using traditional methods. This study systematically evaluated the consistency and performance of transcriptomic-based approaches over time with repeated sampling and with differing experimental approaches (selection of reference condition, grab vs. composite sampling...

From Stream to Spider: How PFAS Move Through Aquatic and Terrestrial Food Webs
Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals that accumulate in the environment and living organisms. A USGS study examined how different PFAS compounds move through a stream ecosystem and are transferred from aquatic to terrestrial food webs. The findings documented that not all PFAS behave the same once they enter the environment, leading to differences in...
Bioenergy and Pesticides: Lessons from the AltEn Bioenergy Plant
Ethanol production from seed corn, while reducing waste and promoting renewable energy, can have environmental and health implications. A USGS study on a former bioenergy plant that received pesticide-coated seeds used for ethanol production, revealed that the process led to contaminated wastewater and solid residue, resulting in elevated pesticide levels in nearby surface waters even after the...
