BP requested that the National Institute for Occupational Health and Safety (NIOSH) do an interim report on the health of oil spill cleanup workers. The NIOSH Oil Spill Worker Health Evaluation is available on the web site of the Lousiana Environmental Action Network and the Lower Mississippi Riverkeepers.
The request asked NIOSH to evaluate potential exposures and health effects among workers involved in Deepwater Horizon Response activities. NIOSH sent an initial team of HHE investigators on June 2, 2010, followed by additional teams. To date, 14 HHE investigators have been on-scene; the investigation is continuing.
