Well 9 drinking water, contributing only to the Air Traffic Control Tower of Mountain Home Air Force Base water system, has levels of Perfluorooctane Sulfanate (PFOS) and Perfluorooctanoic Acid (PFOA) above the U.S. Environmental Protection Agency Health Advisory Level.

What should I do?  What does this mean?

  • Although the health effects are inconclusive, studies reviewed by both the CDC/EPA indicate that long-term exposure to PFOA and PFOS over certain levels may result in adverse health effects, including developmental effects to fetuses during pregnancy or to breastfed infants (e.g., low birth weight, accelerated puberty, skeletal variations), cancer (e.g., testicular, kidney), liver effects (e.g., tissue damage), immune effects (e.g., antibody production and immunity), thyroid effects and other effects (e.g., cholesterol changes).
  • EPA’s health advisory levels were calculated to offer a margin of protection from a lifetime of exposure against adverse health effects to the most sensitive populations: fetuses during pregnancy and breastfed infants. The health advisory levels are calculated based on the drinking water intake of lactating women, who drink more water than other people and can pass these chemicals along to nursing infants through breastmilk.
  • ​Boiling, freezing, or letting water stand does not reduce the PFOS/PFOA level.

What is being done?
Bottled water will be provided to Tower personnel until a permanent solution can be implemented.
