Health effects of PFAS

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a large group of synthetic chemicals that are flame-resistant and repel oil, stains, grease and water.

These compounds do not change or break down easily and, as a result, are widely distributed in the environment and can be found in air, water and soil. In recent years, experts have become increasingly concerned about the potential effects of high concentrations of PFAS on human health.

How PFAS affect health

There is ongoing research to understand the health effects that PFAS may have. Some PFAS have been studied more than others (specifically perfluorooctanoic acid (PFAO) and perfluorooctane sulfonate (PFOS), and scientists are still learning about the health effects of exposure to combinations of PFAS.

Exposure to PFAS or the presence of PFAS in your body does not necessarily mean you will have health problems now or in the future, but there is evidence that exposure to PFAS can lead to negative health effects.

Some studies in humans exposed to PFAS have shown that certain PFAS may increase the potential risk for several adverse medical conditions, including:

• negative impact on growth, learning and behavior of infants and older children

• decreased chances of getting pregnant

• alteration of the body's natural hormones

• increased cholesterol levels

• negative impact on the immune system

• increased risk of cancer

  
  

Based on available research, health advisory levels and water-related standards are set at a level that protects people, including sensitive populations such as pregnant women and infants, from these health effects.

How to reduce exposure to PFAS

Filter the water

Granular activated carbon and reverse osmosis filters can reduce PFAS in water. When PFAS in water exceeds the Wisconsin Recommended Groundwater Compliance Standards of 20 parts per billion, we recommend using bottled water or a filtration system certified for PFOS and PFOA reduction for drinking, cooking, preparing food or infant formula, washing fruits or vegetables, brushing teeth, or feeding pets.
