Questions about PFAS

    Frequently Asked Questions


-What are PFAS?

They are a group of man-made chemicals that have been in use since the 1940’s.  PFAS are, or have been found in a wide variety of consumer products and in firefighting foam.  PFAS manufacturing and processing facilities, airports, and military installations are some of the contributors of PFAS releases into the air, soil, and water. Because of their widespread use, most people have been exposed to PFAS and there is evidence that exposure to certain PFAS may lead to adverse health effects.

-Are we the only ones dealing with PFAS issues?

            No, they have been detected in water systems all across the U.S. and around the world.  We were chosen for early testing due to our proximity to some manufacturers in the area who use/d substances known to have PFAS compounds in them.  


-Is the discoloration of the water currently seen due to PFAS?

            No, there is no correlation. The discoloration is due to a failure in the computer system controlling the water tower levels and well pump operation.  Currently we have a temporary fix on the system that is operating 1 well pump, and we manually run the other 2 well pumps daily as needed.  This change in pressure and flow is stirring up some rust and sediment inherent in an old system with metal water pipes. The water is tested daily by our Public Works staff and is still within safe drinking water guidelines set by the IA DNR.   A completely new control system is being designed & built, but unfortunately it takes time to build a computer and sensor system this complex and specific only to our water system, as every town is different.   Thank you for your patience on this matter as we continue to pursue the best fix for the issue.


-Does bottled water have PFAS?

Yes, possibly. A study, published in the journal Water Research and led by Johns Hopkins University researchers, detected PFAS substances in 39 out of more than 100 bottled waters tested, in some cases at levels deemed concerning by water quality experts.Jun 18, 2021 


-Do water filters get rid of PFAS?

Maybe.  A new study by scientists at Duke University and North Carolina State University finds that – while using any filter is better than using none – many household filters are only partially effective at removing perfluoroalkyl substances, commonly known as PFAS, from drinking water.




As of right now we are in a “test & wait” phase on PFAS issues.   We are in regular contact with the Iowa Department of Natural Resources and the U.S. EPA with our test results.  We are waiting for any recommendations from them for level reduction or removal with current or new technology, and will update residents whenever we have new information.
