Northrop Grumman/Naval Weapons Industrial Reserve Plant Facilities

Health Consultation

The New York State Department of Health, in partnership with the Agency for Toxic Substances and Disease Registry, prepared a Public Comment draft Health Consultation for the Northrop Grumman/Naval Weapons Industrial Reserve Plant (NWIRP) facilities located in Bethpage, Nassau County, and Calverton, Suffolk County, Long Island, New York.

This health consultation was prepared in response to a specific request for information about health risks associated with exposure to contaminants in groundwater that originated from the Northrop Grumman/NWIRP facilities. The New York State Department of Health evaluated the available historic and recent analytical data on regulated contaminants in public water supply wells and area monitoring and irrigation wells to determine if these drinking water or air exposures could cause harm to human health. Based on this evaluation, the New York State Department of Health and the Agency for Toxic Substances and Disease Registry have the following health advice:

  • Currently, drinking or using water from the public water supplies affected by the Northrop Grumman/NWIRP facility in Bethpage, Nassau County, is not expected to harm people’s health.
  • In the past, and prior to installation of treatment systems to remove volatile organic compounds, use of drinking water contaminated with trichloroethene from the Bethpage Water District Well 6-1 could have harmed people’s health. Past long-term ingestion and inhalation exposure to tetrachlorothene and 1,1,1-trichloroethane in Bethpage Well 6-1 is not expected to have harmed people’s health.
  • Past long-term ingestion and inhalation exposure to trichloroethene in the other public water supplies (other than Bethpage Well 6-1) affected by Northrop Grumman/NWIRP facility in Bethpage is not expected to harm people’s health.
  • Exposure to facility related contaminants through the use of unpermitted private wells may have occurred, however such exposures are unlikely.
  • Currently, drinking or using water from public water supplies in Calverton, Suffolk County, is not expected to harm people’s health.
  • Past use of drinking water from the Peconic River Sportsman Club private well (Suffolk County) is not expected to harm people’s health.
