Three-dimensional geologic model of the Arbuckle-Simpson aquifer, south-central Oklahoma
The Arbuckle-Simpson aquifer of south-central Oklahoma encompasses more than 850 square kilometers and is the principal water resource for south-central Oklahoma. Rock units comprising the aquifer are characterized by limestone, dolomite, and sandstones assigned to two lower Paleozoic units: the Arbuckle and Simpson Groups. Also considered to be...Faith, Jason R.; Blome, Charles D.; Pantea, Michael P.; Puckette, James O.; Halihan, Todd; Osborn, Noel; Christenson, Scott; Pack, Skip

This report contains digital data and image files of aeromagnetic anomalies in the Sawatch Range of central Colorado. The primary product is a data layer of polygons with linked data records that summarize previous interpretations of aeromagnetic anomalies in this region. None of these data files and images are new; rather, they are presented in...Bankey, Viki
USGS Toxic Substances Hydrology Program, 2010
The U.S. Geological Survey (USGS) Toxic Substances Hydrology Program adapts research priorities to address the most important contamination issues facing the Nation and to identify new threats to environmental health. The Program investigates two major types of contamination problems: * Subsurface Point-Source Contamination, and * Watershed...Buxton, Herbert T.
Modeling Climate Change and Sturgeon Populations in the Missouri River
The U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC), in collaboration with researchers from the University of Missouri and Iowa State University, is conducting research to address effects of climate change on sturgeon populations (Scaphirhynchus spp.) in the Missouri River. The CERC is conducting laboratory, field,...Wildhaber, Mark L.
Agricultural wetlands as potential hotspots for mercury bioaccumulation: Experimental evidence using caged fish
Wetlands provide numerous ecosystem services, but also can be sources of methylmercury (MeHg) production and export. Rice agricultural wetlands in particular may be important sites for MeHg bioaccumulation due to their worldwide ubiquity, periodic flooding schedules, and high use by wildlife. We assessed MeHg bioaccumulation within agricultural...Ackerman, Joshua T.; Eagles-Smith, Collin A.
The toxicological geochemistry of Earth materials: An overview of processes and the interdisciplinary methods used to understand them
A broad spectrum of earth materials have been linked to, blamed for, and/or debated as sources for disease. In some cases, the links are clear. For example, excessive exposures to mineral dusts have long been recognized for their role in diseases such as: asbestosis, mesothelioma, and lung cancers (asbestos); silicosis and lung cancer (silica...Plumlee, Geoffrey S.; Morman, Suzette A.; Ziegler, Thomas L.

The medical geochemistry of dusts, soils, and other Earth materials: Chapter 7
A quick scan of newspapers, television, science magazines, or the internet on any given day has a fairly high likelihood of encountering stories (accompanied by headlines such as those above) regarding human health concerns linked to dusts, soils, or other Earth materials. Many such concerns have been recognized and studied for decades, but new...Plumlee, Geoffrey S.; Ziegler, Thomas L.

The world's largest breeding population of ospreys is coping well with the long-lasting residues of toxic chemicals that were banned decades ago but remain in the Chesapeake Bay food chain at varying levels, such as the pesticide DDT and insulating chemicals known as PCBs.
Scientists have collected and analyzed 84 environmental samples to establish baseline data prior to any active uranium mining activities at the Canyon Uranium Mine, located south of Grand Canyon National Park.
USGS scientists have detected toxins known as microcystins produced by various forms of algae in 39 percent of the small streams assessed throughout the southeastern United States. Their recent study looked at 75 streams in portions of Alabama, Georgia, North Carolina, South Carolina and Virginia.
WASHINGTON—The President’s fiscal year (FY) 2017 budget request for the U.S. Geological Survey reflects the USGS's vital role in addressing some of the most pressing challenges of the 21st Century by advancing scientific discovery and innovation.
The U.S. Geological Survey is implementing new measures that will improve public access to USGS-funded science as detailed in its new public access plan.
Between 1990 and 2010, global mercury emissions from manmade sources declined 30 percent, according to a new analysis by Harvard University, Peking University, the U.S. Geological Survey, the Max Planck Institute for Chemistry, and the University of Alberta. These results challenge long-standing assumptions about mercury emission trends.
Medical Geology is an earth science specialty that concerns how geologic materials and earth processes affect human health.
No, it’s not a sports drink for leeches, although that’s what it sounds like. Leachate is the solution (or suspension) that forms when liquid travels through a solid and removes some components of that solid with it. Those components may be dissolved or suspended within the liquid.
For the first time, land and resource managers in the Great Lakes will be able to distinguish between the various sources of mercury in the environment, a toxic chemical of significant concern in the region. This is thanks to a new tool that “fingerprints” the mercury, developed by the U.S. Geological Survey and the University of Wisconsin-Madison.
Fish health may be affected by pharmaceuticals in treated wastewater released into streams and other water bodies, according to a recent laboratory and field study by the Aquatic Toxicology Laboratory at St. Cloud State University and the U.S. Geological Survey (USGS).
New research from the U.S. Geological Survey details that even after the storage and/or treatment of leachate – liquid waste that moves through or drains from a landfill − it can still contain a multitude of chemicals and reflects the diverse nature of residential, industrial, and commercial waste discarded into landfills in the United States.
USGS scientists have conducted the first-ever field measurements of anammox activity in groundwater, demonstrating that nitrogen removal from groundwater can occur through the action of naturally occurring bacteria. This research was conducted in collaboration with partners from the Virginia Institute of Marine Science and the University of Connecticut.
