Understanding AFFF Contamination: Exploring the Impact of PFAS Chemicals on Communities

Firefighting foam, also known as Aqueous Film-Forming Foam (AFFF), has long been used by firefighters to suppress flammable liquid fires.

However, the widespread use of AFFF has raised concerns about the environmental and health impacts of per- and polyfluoroalkyl substances (PFAS) chemicals found in these foams. In this blog post, we’ll delve into the issue of AFFF contamination and its profound impact on communities across the globe.

The Emergence of AFFF Contamination

The use of AFFF became widespread in the mid-20th century as an effective firefighting tool for combating liquid fuel fires, such as those involving petroleum or jet fuels.

AFFF contains PFAS chemicals, which are highly effective at extinguishing fires by forming a thin film on the fuel surface, depriving the fire of oxygen and suppressing its spread. However, the persistence and mobility of PFAS chemicals have led to widespread environmental contamination, posing serious risks to human health and ecosystems.

Environmental and Health Impacts

PFAS chemicals, including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are known as “forever chemicals” due to their persistence in the environment and bioaccumulative properties.

These chemicals do not break down easily and can persist in soil, water, and air for decades, leading to widespread contamination of drinking water sources, soil, and aquatic ecosystems.

Exposure to PFAS chemicals has been linked to a range of adverse health effects, including:

  • Increased risk of certain cancers, such as kidney and testicular cancer
  • Developmental delays and reproductive problems
  • Liver damage
  • Compromised immune function

Communities located near military bases, airports, firefighting training facilities, and industrial sites where AFFF has been used extensively are at particularly high risk of AFFF contamination. In many cases, residents may unknowingly be exposed to harmful levels of PFAS chemicals through contaminated drinking water, soil, and air.

Legal Action and Accountability

As awareness of the risks associated with PFAS contamination has grown, affected communities and individuals have increasingly turned to legal action to seek accountability and compensation for damages.

Numerous lawsuits have been filed against manufacturers of AFFF products, firefighting foam users, and other parties responsible for PFAS contamination.

Efforts to Address AFFF Contamination

In response to growing concerns about PFAS contamination, regulatory agencies and lawmakers have taken steps to address the issue and mitigate the impacts of AFFF contamination.

This includes efforts to regulate PFAS chemicals, establish cleanup standards, and provide support for affected communities.


AFFF contamination poses significant environmental and health risks to communities around the world. Understanding the sources and impacts of PFAS contamination is crucial for addressing this complex issue and protecting public health and the environment.

Efforts to hold responsible parties accountable, regulate PFAS chemicals, and support affected communities are essential steps toward addressing the challenges posed by AFFF contamination.
