USGS specializes in science at the environment-health interface, by characterizing the processes that affect the interaction among the physical environment, the living environment, and people, and the resulting factors that affect ecological and human exposure to disease agents.Our Science Strategy
The USGS is developing methods to measure new pesticides and their byproducts in environmental media, conducting studies on the fate of these chemicals, and assessing exposure and potential effects on fish, wildlife, and human health.
This investigation focuses on understanding mercury sources, pathways and key processes in the environment, with particular emphasis on mercury methylation and accumulation in aquatic ecosystems.
The objective of research at the Amargosa Desert Research Site, Nevada, is to improve understanding of processes controlling the migration and fate of contaminants in arid environments, and the environmental-health implications of disposed radioactive and industrial waste.
The USGS is conducting source-to-receptor research on a broad range of chemical and microbial contaminants including pharmaceuticals, personal care products, pathogens, antibiotic resistant genes, and natural toxins that are not commonly considered in environmental research but have the potential to impact environmental health.
The USGS is investigating the occurrence and environmental effects of complex mixtures of both natural and man-made chemicals in environmental waters.
This investigation focuses on the long-term persistence in soils and groundwater of petroleum hydrocarbon spills, including crude oil and refined petroleum fuels. The study site near Bemidji, MN, is a laboratory for developing site assessment tools and understanding chemical changes affecting human and environmental health that occur during natural attenuation of petroleum hydrocarbons.
The USGS is investigating the hydrological, geochemical, and microbiological processes controlling contaminant fate in fractured-rock aquifers. Long-term field experiments are currently conducted at a former aircraft engine test facility in West Trenton, New Jersey, where high concentrations of trichloroethene persist in sedimentary rocks despite two decades of groundwater pumping and...
As part of the Comprehensive Everglades Restoration Plan, water managers are planning to use treated wastewater from the South District Wastewater Treatment Plant (WWTP) to supplement the canal waters that will be used to rehydrate wetlands adjacent to the Biscayne National Park (Park).
Coral reefs around the world are exposed to a number of environmental contaminants. USGS researchers investigate the issue of contamination on the reefs around the U.S. Virgin Islands.
USGS researchers evaluate the impact of a pesticide on two imperiled butterfly species in the Florida Keys.
USGS researchers investigate the effects of methylmercury contamination on reproduction of the Eastern mosquitofish, a common fish in South Florida.
Pathogens and infectious disease play a role in some recent species extinctions and are likely to impact biodiversity in the future. Environmental DNA - eDNA - is coupled with traditional amphibian sampling methods to determine the distribution and prevalence of the amphibian chytrid fungus, also known as Bd, in the southeastern US. ...

A special issue on volcanic centers as targets for mineral exploration
NEPTUNE or Pluto? Since the days of Hutton and Werner, every generation of economic geologists has addressed this question in a new light. Most papers in this special issue deal with the thin and leaky roof of Pluto's underworld. It allows hot emanations from Hades to leak out, only to be quenched and diluted by waters percolating down from...Elston, Wolfgang E. ; Plumlee, Geoffrey S.
Mineralogy, paragenesis, and mineral zoning of the Bulldog Mountain vein system, Creede District, Colorado
The Bulldog Mountain vein system, Creede district, Colorado, is one of four major epithermal vein systems from which the bulk of the district's historical Ag-Pb-Zn-Cu production has come. Ores deposited along the vein system were discovered in 1965 and were mined from 1969 to 1985.Six temporally gradational mineralization stages have been...Plumlee, Geoffrey S.; Heald Whitehouse-Veaux, Pamela

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.
According to the first-ever study of pesticide residues on field-caught bees, native bees are exposed to neonicotinoid insecticides and other pesticides. This report was conducted by the U.S. Geological Survey and published in the journal Science of the Total Environment.
