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

GIS-based landscape analysis to identify sources of endocrine disrupting chemicals

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.

Hurricane Season—LMGWSC has the Louisiana Coast Covered

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.
