Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
Environmental health science focuses on the interface between health and the environment, where interactions among people, the environment, and other living organisms affect the risk of toxicologic and infectious disease.

De facto wastewater reuse from Wastewater Treatment Facilities (WWTF) has the potential to contribute unregulated Endocrine Disrupting Chemicals. To visualize the typical contributions of treated effluent into Shenandoah River watershed streams, an ArcGIS model of WWTFs, NHDPlus Version 2 (USGS and EPA 2012) stream networks, and USGS Streamgages across the Shenandoah River watershed was developed.

June 1 marks the beginning of hurricane season. Should storms arrive on the Louisiana coast, the people in coastal communities across the State, along with many Federal, State, and local agencies will need to know how the storms are affecting the coastal and low-lying areas.The USGS maintains an extensive network of coastal gages that provides critical time-sensitive water level.
The USGS partners with the Association of American State Geologists (AASG) to develop a distributed archive of standardized geoscience information for the nation.
The Protected Areas Database of the United States (PAD-US) Viewer provides a spatially explicit inventory that lets any user – from the general public to professional land managers – explore the protected areas network anywhere in the United States and allows them to easily use this inventory in conservation, land management, planning, recreation and other uses.
The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. This dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program. The spatial data layer was created using Landsat satellite imagery and a detailed vegetation and land use classification system.
The viewer allows exploring the condition of stream and coastal habitats across the country at various spatial scales, reported in Through a Fish's Eye: The Status of Fish Habitats in the United States 2010. It offers a variety of base maps and provides one-click access to more detailed information on landscape disturbances and habitat scores for individual stream catchments.
Online data set provides an estimate of the abundance and spatial distribution of chemical elements and minerals in soils of the conterminous United States and represents a baseline for soil geochemistry and mineralogy against which future changes may be recognized and quantified.
