PFBA stands for perfluorobutanoic acid.  It is from a family of chemicals called perfluorochemicals, or PFC’s. A number of companies manufacture PFC’s to be used in household and industrial products. Some of these products include lubricants, fire retardents, pesticides and surfactants.

In spring of 2006, the Minnesota Department of Health developed methods to look for PFC’s. Analysis of the water samples revealed that PFBA was widespread in the South East Metro area of the Twin Cities.    The Minnesota Department of Health and the United States EPA are currently doing more studies on PFBA. As results from these studies become available, the Minnesota Department of Health will revise it’s advice for PFBA.  More detailed information for PFBA in the South East Metro area can be found at:

PFBA moves freely through ground water and does not breakdown or degrade.  The chemistry of PFBA suggests that it does not easily evaporate from water. Boiling water will not remove PFBA or other PFC’s from the water.  At this time, the exposure of most concern is through drinking water and not breathing it in or absorbing it through a person’s skin. 

If PFBA has been detected in your drinking water and you wish to reduce your exposure, the Minnesota Department of Health suggests a filter system containing granular activated carbon would be a good choice.  Systems using granular activated carbon will reduce PFC’s including PFBA.
