Two non-native bigheaded carp species have invaded the Illinois River system and are a potential threat to the Great Lakes ecosystem. Discharges from industry, wastewater treatment plants, and urban and agricultural runoff, may be a factor contributing to the stalling of the upstream movement of the bigheaded carp population front near Illinois Waterway mile 278. In 2015, the U.S. Geological Survey collected 4 sets of water samples under a range of seasonal and hydrologic conditions from 3 locations upstream and 4 locations downstream from river mile 278 using a Lagrangian-style sampling strategy. Water samples were analyzed for over 639 constituents of which 280 were detected at least once, including many anthropogenic...

Precipitation, suspended-sediment, and water-quality data were collected by the U.S. Geological Survey (USGS) in cooperation with the U.S. Army on two bases in Colorado, U.S. Army Garrison Fort Carson and Piñon Canyon Maneuver Site, during water years 2016–18. Data were collected to assist in understanding the potential effects of military training maneuvers on water resources and water quality for various streams on each base.

Advances in drilling technique have facilitated a rapid increase in hydrocarbon extraction from energy shales, including the Williston Basin in central North America. This area overlaps with the Prairie Pothole Region and greater than 35% of wetlands are less than or equal to 1 km from a petroleum-related well. Legacy practices often released saline co-produced waters (brines) that were chloride rich wastes, affecting wetland water quality directly or persisting in sediments. Despite the potential threat of brine contamination to aquatic habitats, there has been little research into their ecological effects. We capitalized on a gradient of legacy brine-contaminated wetlands in northeast Montana to conduct laboratory...
