What are PFAS?
PFAS (formerly PFOS and PFOA) stands for Per - and Polyfluorinated substances. These are known as “forever chemicals” because they resist heat, water, and grease. Some PFAS have been phased out of production. However, there is still PFAS found in many everyday consumer products like shampoo, makeup, non-stick cookware, fast food packaging, clothing, carpeting and more.
PFAS are widespread across the US. According to the Environmental Working Group, some areas have a higher PFAS concentration than others. The Environmental Protection Agency (EPA) has set the limit for PFAS in public drinking water systems at 4 parts per trillion (ppt). This legally enforceable drinking water standard will protect approximately 100 million people from six specific PFAS.
According to a news release from the Wausau Water Works, all six of the city's drinking water wells tested between 23 parts per trillion and 48 parts per trillion. The Water Works serves 16,000 customers in the Wausau area, which is home to just under 40,000 residents. (Source)
What are the health effects of PFAS found in water?
PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid) can be found in water. These chemicals do not break down and stay in the environment, which can build up in soil and contaminate ground and surface water. Long-term exposure can also cause build-up in your blood, kidneys and liver, leading to significant health issues, such as:
  • Developmental effects*
  • Liver damage
  • Reproductive issues
  • Thyroid imbalance
  • Immune system deficiencies
  • Some cancers
*These health effects are especially dangerous for pregnant women and infants.
Public water systems must notify customers if there are high levels of PFAS in their drinking water. Consumers can contact their local water supplier to ask for information on PFOA and PFOS in their drinking water and request a copy of the Consumer Confidence Report.
