Studies showing how human activities affect environmental and ecological health and how the quality of our environment and wildlife affects human health.
Guide to major U.S. environmental statutes and corresponding regulations on air quality, fish and wildlife conservation, cultural and historic resources, solid and hazardous substances, public lands, farmlands, and water resources.
Listing of USGS research and monitoring projects on mine drainage, in order to promote cooperation and collaboration among scientists working on problems related to mining and the environment.
Imagery, sampling information, and other data intended for use in assessing and remediating environmental problems related to the oil spill in the Gulf of Mexico in 2010
Outlines processes that control the release of metals and acidic waters from inactive mines and mineralized areas, the transport of metals and acidic waters to streams, and the fate and effect of metals and acidity on downstream ecosystems.
Outlines tactical problems that make it difficult for beach managers to use scientific information to make beach closure and advisory decisions. Explains methodologies we are using to address those problems and better prepare local decision makers.
People who manage recreational areas need better, more timely estimates of the likelihood that the beach and lake waters will be hazardous to human health, and which factors cause those hazards.
The Sacramento-San Joaquin River Delta is the hub of California's water system and an important habitat for fish and wildlife. USGS research has provided resource managers and other stakeholders with a good understanding of how pesticides enter the Delta.
Contaminants from mines move more easily from ore materials and mine waste piles to surrounding estuaries and living organisms when water moves through the mine site. Geochemical results shown here will help people mitigate the negative effects.
