PFAS in Drinking Water


Detecting and Treating PFAS in Water

PFAS, also known as “forever chemicals,” significantly threaten the environment and health due to their persistence. Many communities in Wisconsin struggle to treat and reduce the spread of PFAS in municipal water systems and the surrounding ecosystem. These man-made chemicals also contaminate private wells and are more widespread than previously believed.

What is PFAS?

PFAS (Per- and Polyfluoroalkyl Substances) are a group of human-made chemicals used in various industries and consumer products for their water- and grease-resistant properties. PFAS include substances like PFOA and PFOS. Due to their persistence in the environment, PFAS have been detected in drinking water sources.

Where does it come from?

PFAS can enter the environment through industrial discharges, the use of firefighting foams, and the application of certain consumer products. These substances can accumulate in soil and water, leading to contamination of water sources, including groundwater and surface water.

Are PFAS a health hazard?

Yes, PFAS are considered a health hazard. Prolonged exposure to elevated levels of PFAS has been associated with various health issues, including developmental effects, liver damage, immune system disruption, and an increased risk of certain cancers. The potential health risks have led to increased awareness and regulatory efforts to address PFAS contamination.

When should I test?

Testing for PFAS is recommended, especially if you live near industrial facilities, military bases, or areas where firefighting foam has been used. Additionally, individuals relying on private wells for their water supply should consider testing, as PFAS contamination can affect groundwater. Public water suppliers may also conduct testing, but homeowners with private wells should arrange independent testing.

If my water tests positive, what should I do next?

Stop using contaminated water: Avoid using water for drinking or cooking until the issue is addressed. Seek alternative water sources for consumption.

Test other water sources: If you have additional water sources, test them for PFAS to assess the extent of contamination.

What does “certified” mean?

Certification mandates stringent standards. Wisconsin residents are urged to choose products certified by organizations such as the American National Standards Institute (ANSI) and the National Sanitation Foundation (NSF).

NSF certifies products to safeguard human health. NSF standards ensure that a filter can reduce PFOA and PFOS levels below the EPA’s health advisory level of 70 parts per trillion.

Moreover, NSF-certified devices can effectively surpass Wisconsin’s groundwater standards, often reaching undetectable levels.
