Deepwater Horizon Oil Spill USGS Water-Quality Response Resources and Information
The U.S. Geological Survey (USGS) as part of the U.S. Department of the Interior (DOI) responded to the 2010 Deepwater Horizon Oil Spill in the Gulf of Mexico by establishing baseline conditions in water chemistry and bottom sediments prior to landfall of the oil spill. After the spill reached shore (referred to as "landfall"), the USGS conducted additional sampling. Teams of scientists collected samples in Texas, Louisiana, Mississippi, Alabama, and Florida. These sampling locations include barrier islands and coastal wetlands that are critical to fish and wildlife in the Gulf of Mexico.
