There is no hiding the hard water in Hunstville, Alabama, but what some people do not know is there is also a presence of PFOS's and PFOA's. But what are they? Perfluorooctanesulfonic acid is the main ingredient in substances like tape and stain repellents. According to a study by the OECD "PFOS is a persistent bio-accumulative and is toxic to mammalian species." The EPA has established health advisories for PFOA AND PFOS's and more studies continue to be released on the affect of human health due to these global contaminants. The C Family had us install a chemical filter that will protect against these harmful contaminants. Call us today if you are curious what is in your water.
