Amid rising environmental concerns, the focus has turned to aqueous film-forming foam (AFFF), a firefighting agent renowned for its efficacy in combating flammable liquid fires. AFFF’s widespread use underscores the urgency of addressing its environmental impact. 

However, the environmental consequences of AFFF are increasingly alarming. The authorities are showing concern with studies linking its use to the presence of per- and polyfluoroalkyl substances (PFAS) in water sources.

In this article, we delve into the environmental impact of AFFF, exploring the urgent need for comprehensive remediation strategies to mitigate its long-lasting effects.

Understanding AFFF’s Environmental Impact

Understanding AFFF begins with recognizing its composition and purpose. AFFF is a firefighting foam designed to rapidly extinguish flammable liquid fires by forming a blanket-like film that cuts off the fire’s oxygen supply.

As per ConsumerNotice.org, AFFF includes water along with additives such as propylene glycol and ethylene, which enhance its effectiveness. The foam concentrate must be diluted with water before application and typically comes in 3% and 6% formulations, depending on the desired concentration.

AFFF is essential for suppressing fires that cannot be easily managed with water or traditional petroleum-based firefighting products. To make this mixture creamy and more effective, AFFF contains chemicals called per- and poly-fluoroalkyl substances, or PFAS. Yet, PFAS are enduring artificial substances recognized for their environmental and health hazards.

These chemicals have been associated with numerous detrimental health impacts, such as cancer, immune system disruption, and developmental problems. Moreover, PFAS do not break down easily in the environment, leading to long-term contamination of soil and water sources. As a result, using AFFF has raised concerns about its environmental impact and the need for remediation strategies to mitigate these effects.

Health Risks Associated with AFFF Contaminants

AFFF and its contaminants, specifically PFAS, are widely used and can be found in various applications beyond firefighting. PFAS are present in many consumer products, such as non-stick cookware, stain-resistant fabrics, and food packaging. Additionally, PFAS can enter the environment through industrial discharges, landfills, and wastewater treatment plants.

PFAS are pervasive globally, with the majority of individuals experiencing low-level exposure. PFAS is present in the bloodstream of nearly all individuals in minor quantities. The risk of health issues stemming from PFAS exposure varies and is influenced by factors such as the level, regularity, and duration of exposure. PFAS exposure has the following impact on human health.

• Fertility issues
• Pregnancy-induced hypertension
• High cholesterol level
• Low immunity
• Increased risk of cancers like testicular and kidney cancer
• Liver damage
• Increased risk of thyroid disease
• Increased risk of asthma

The health hazards linked to PFAS exposure are alarming. Moreover, PFAS, termed “persistent chemicals,” persist in the environment and the human body, accumulating over time and presenting enduring health threats.

Ecological Effects of AFFF Contamination

The ecological effects of AFFF contamination are significant and far-reaching. When AFFF is used to suppress fires, the foam can enter soil and water systems, leading to widespread contamination of aquatic and terrestrial ecosystems. The chemicals in AFFF, i.e., PFAS, can bioaccumulate in plants and animals, leading to potential ecosystem-wide impacts.

These contaminants can disrupt wildlife’s reproductive and immune systems, affect plant growth, and alter the composition of microbial communities. Furthermore, PFAS can persist in the environment for extended periods, posing ongoing threats to ecosystem health. Efforts to remediate AFFF contamination are crucial to mitigate these ecological effects and protect vulnerable ecosystems.

Urgency for Remediation

According to EWG.org, the latest data released by the EPA showed almost 900 spills of AFFF made with PFAS. This forever chemical has entered local waterways around 900 times since 1990. The release was mostly made by the Department of Defense and federal facilities, but some spills were civilian firefighting events and commercial harbors. It’s a matter of concern now, and there is an urgency for remediation.

Urgent remediation of AFFF and its contaminants requires a multi-faceted approach to address both the immediate and long-term impacts of contamination. First, immediate actions should focus on containment and cleanup of contaminated sites to prevent further spread of PFAS into the environment. It may involve removing contaminated soil, treating contaminated water sources, and implementing measures to prevent further runoff.

Additionally, efforts should be made to assess and monitor the extent of contamination to guide remediation efforts effectively. Long-term remediation strategies should prioritize removing or treating PFAS from affected areas. There must be development and use of alternative firefighting agents that are less harmful to the environment.

Public awareness and education campaigns are also essential to inform communities about the risks of AFFF contamination and the importance of remediation efforts.

Regulatory and Legal Considerations

Due to the environmental and health risks, regulatory and legal considerations surrounding AFFF and its use are becoming increasingly stringent. Regulatory agencies like the Environmental Protection Agency are establishing stricter guidelines for using and disposing of AFFF to minimize environmental contamination.

According to TorHoerman Law, lawsuits have been filed against manufacturers and users of AFFF, alleging negligence. They also seek compensation for damages caused by PFAS exposure through these lawsuits. 

The AFFF lawsuit plays a crucial role in holding responsible parties accountable for the environmental and health impacts of AFFF contamination. Furthermore, these legal actions can improve regulations and practices surrounding AFFF use. It will ultimately benefit the public by reducing the risks associated with PFAS exposure and promoting environmental protection.

Remediation Strategies

Remediation strategies for AFFF contamination are essential to mitigate the environmental and health risks associated with its use. Several approaches can be employed to remediate AFFF-contaminated sites, depending on the extent and severity of contamination.

One common strategy is using activated carbon or other absorbent materials to trap and remove PFAS from soil and water. Another approach is using specialized treatment technologies, such as ion exchange or advanced oxidation, to break down PFAS molecules into less harmful by-products.

Additionally, efforts can be made to contain and prevent the further spread of contamination through the use of barriers or extraction wells. Long-term monitoring and maintenance of remediated sites are also critical to ensure the effectiveness of remediation efforts.

To successfully remediate AFFF contamination, a combination of these strategies, tailored to each site’s specific characteristics, is necessary.

Government and Industry Response

Government and industry responses to AFFF contamination have evolved as awareness of the issue grows. In recent years, regulatory agencies such as the Environmental Protection Agency (EPA) have addressed AFFF contamination by issuing guidelines and regulations. It is to limit the use and disposal of PFAS-containing firefighting foams.

Additionally, some states have implemented regulations to further restrict the use of AFFF and require remediation of contaminated sites. The Department of Ecology, Washington, passed a law in 2018 to restrict the use of AFFF because it contains PFAS. Lately, a public review has been conducted on the draft Environmental Impact Statement for AFFF, outlining alternative solutions to the suggested collection and disposal program.

On the industry side, there has been a push towards developing alternative firefighting foams that do not contain PFAS. Some companies have also implemented voluntary programs to remediate AFFF-contaminated sites and reduce their environmental footprint. However, opponents contend that stricter regulations and proactive actions are necessary to tackle the extensive contamination resulting from AFFF.
