Gulf Study Logo: A health study for oil spill clean-up workers and volunteers


The NIEHS is leading the GuLF STUDY  – a health study for oil spill workers and volunteers following the 2010 Deepwater Horizon Oil Spill.


The GuLF STUDY is a health study specifically for people who helped clean up the Deepwater Horizon Gulf Oil Spill.


  • The GuLF STUDY will also include some people who took the worker safety training, but did not get to do cleanup work.
  • The GuLF STUDY will help us learn if oil spills and exposure to crude oil and dispersants affect our physical and mental health.
  • Over time, the GuLF STUDY will generate some important data that may help provide information on policy decisions on healthcare and health services in the region.  
  • The GuLF STUDY is the largest study ever conducted on possible short- and long-term health effects of oil spills.
  • The GuLF STUDY will be run by scientists at the world’s top medical research organization, the National Institutes of Health.
