Protect Your Health: Understanding PFAS in Tap Water

Understanding PFAS in Water

When it comes to ensuring the water in your home is safe to drink, it’s important to be informed about various contaminants that could be lurking in your tap water. One such group of chemicals that has gained attention are PFAS, which may pose health risks if present in significant amounts.

What are PFAS?

PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been used in industry and consumer products around the world since the 1940s. You might often hear PFAS referred to as “forever chemicals,” due to their persistence in the environment and the human body – they do not break down easily and can accumulate over time.

There are numerous PFAS compounds, but two of the most studied and commonly found in the environment are PFOA (perfluorooctanoic acid) and PFOS (perfluorooctanesulfonic acid). These substances have been used to make cookware, food packaging, stain-resistant carpets and fabrics, and even in firefighting foams.

For more detailed information on PFAS, including their chemical structure and properties, take a look at what are pfas.

Sources of PFAS

PFAS can enter drinking water supplies from various sources. One common source is the manufacturing sites where these chemicals are produced or used to manufacture other products. Additionally, facilities that use PFAS in their processes, such as chrome plating operations or electronics manufacturing plants, can also be sources of contamination.

Another significant contributor to PFAS in water is the use of firefighting foams, particularly at military bases and airports where practice drills and emergency responses have utilized PFAS-containing foams. These substances can leach into the soil and contaminate groundwater, which can then serve as a source of PFAS for nearby wells and public water systems.

Landfills are also a potential source of PFAS contamination. Products that contain PFAS and are thrown away may release these chemicals as they break down, potentially leaching into groundwater.

Here’s a summary of the primary sources of PFAS contamination:

• Industrial sites
• Firefighting training and response sites
• Landfills
• Wastewater treatment plant effluent

Understanding the sources of PFAS is crucial for addressing pfas water contamination and protecting public health. If you rely on well water, it’s wise to be aware of the risks and testing options for pfas in well water.
