Firefighters are often hailed as heroes for their valiant efforts in combating blazes. They have long relied on various tools and technologies to extinguish flames and save lives. Among these tools is the Aqueous Film-Forming Foam (AFFF), a widely used firefighting foam for suppressing flammable liquid fires. However, behind its lifesaving reputation lurks a silent threat.
AFFF has been associated with several life-threatening health conditions because of the presence of the per and polyfluorinated substances in them. According to a ScienceDirect study, AFFF contains PFASs, a group of 5,000 chemicals. Many of these 5,000 chemicals are included in AFFFs for Class B flammable fuel fires.
This article delves into the environmental, health, and societal impacts of AFFF foam. It will shed light on the hidden dangers that this firefighting agent poses.
Understanding AFFF Composition
AFFF is a firefighting foam widely used for suppressing flammable liquid fires. Composed of water, fluorochemical surfactants, hydrocarbon surfactants, and stabilizers, AFFF is designed to create a thin aqueous film on the surface of the fuel. This prevents the release of flammable vapors and suppresses the fire.
The primary component in AFFF is water, which serves as the base for the foam. This aqueous solution facilitates the distribution and application of the foam, allowing it to cover the burning surface and form a cohesive film.
Fluorochemical surfactants, such as fluorotelomer-based compounds, are crucial in AFFF’s ability to spread across hydrophobic liquid surfaces. These surfactants significantly reduce the surface tension of water, enabling the foam to form a stable and durable film on the fuel.
Hydrocarbon surfactants, often derived from synthetic materials, enhance the foam’s ability to spread and adhere to the fuel surface. These surfactants work in conjunction with fluorochemicals to improve the overall effectiveness of the foam in suppressing fires involving flammable liquids.
Health Implications
Exposure to PFAS through AFFF has been linked to various health issues. Studies suggest prolonged exposure may contribute to adverse effects on the liver, kidneys, and immune system. Additionally, PFAS compounds have been detected in human blood, raising concerns about bioaccumulation and the potential for long-term health consequences. The ability of PFAS to persist in the environment for extended periods further amplifies these concerns.
Contamination of drinking water sources is a significant pathway for human exposure to AFFF-related chemicals. Instances of AFFF releases and the subsequent contamination of groundwater have been reported near military bases, airports, and industrial facilities. Such contamination poses a risk to communities relying on these water sources, potentially leading to increased PFAS levels in their drinking water.
Beyond human health, AFFF-related PFAS contamination has also been associated with adverse effects on aquatic ecosystems. The widespread use and release of AFFF into water bodies can lead to bioaccumulation in aquatic organisms. As stated in a recent press release, PFAS is detected in the bloodstream of 99% of the U.S. population.
Consider the example of firefighters and military personnel. These individuals are constantly exposed to AFFF. Hence, they are said to be at an increased risk of developing cancer and other health problems. In fact, many of the affected people have also filed firefighter foam lawsuits against AFFF manufacturers.
If you have been exposed to AFFF and subsequently developed any cancer or other such severe health conditions, you can also file a lawsuit. Through the firefighter foam lawsuit, you can seek compensation for your loss. For instance, you can seek compensation for medical expenses, lost wages, emotional damage, etc.
Environmental Consequences
According to TorHoerman Law, AFFF foam has left an indelible mark on the environment despite its effectiveness in firefighting. One of the most significant concerns is the presence of PFAS in AFFF, known for their resistance to environmental degradation. When AFFF is deployed, PFAS-containing chemicals can infiltrate soil and water, leading to widespread contamination.
- Groundwater contamination: PFAS compounds, due to their persistence, can seep into the ground and contaminate groundwater sources. As a result, communities relying on such water sources may unknowingly expose themselves to these harmful substances, with potential health ramifications.
- Surface water pollution: Runoff from firefighting activities, including using AFFF, can find its way into surface water bodies. This introduces PFAS into aquatic ecosystems, impacting fish and other aquatic life. The bioaccumulation of PFAS in the food chain raises concerns about the potential effects on both wildlife and humans.
- Impact on soil quality: The use of AFFF can also lead to soil contamination. PFAS compounds may accumulate in the soil, posing plant risks and disrupting ecosystems. The consequences of soil contamination are particularly concerning in agricultural areas, where the long-term effects on crops and livestock are not fully understood.
Societal Ramifications
The consequences of AFFF foam extend beyond the environmental and health domains, affecting communities and societies in various ways.
Dealing with the aftermath of AFFF-related contamination requires significant financial resources. Communities grappling with contaminated water supplies, agricultural lands, and ecosystems face the economic burden of remediation efforts, healthcare costs, and potential litigation.
The economic costs can be devastating for treating any condition developed by AFFF exposure. In fact, a 2022 study published in the Springer Journal revealed the costs of treating diseases due to PFAS exposure. The study concluded that it can be as much as $62.6 billion.
The revelation of AFFF’s environmental and health impacts has eroded public trust in firefighting practices and manufacturing industries. Communities may question the adequacy of regulations and demand greater transparency and accountability from those responsible for AFFF-related contamination.
Regulatory Responses
In response to the growing awareness of AFFF-related issues, regulatory bodies worldwide are taking steps to address them.
- Regulatory restrictions: Several countries and regions have implemented or proposed restrictions on using certain types of AFFF that contain PFAS. Regulatory agencies are working to phase out the use of PFAS-containing foams in non-emergency situations and explore alternative firefighting technologies.
- Remediation efforts: Remediation of AFFF-related contamination sites is complex and challenging. Regulatory bodies are working alongside industries to develop effective remediation strategies, including treating contaminated water sources and soil.
One example of how government agencies are working on PFAS control can be seen in the Department of Defense (DoD) report. Last year, it identified over 700 installations where PFAS studies are conducted across the US. Testing is also done to determine the damages. The testing and cleaning costs can go up to billions.
To conclude, it is imperative to confront the silent threat posed by AFFF foam. The long-term consequences of environmental contamination, health risks, and societal impacts demand urgent attention and concerted efforts from regulatory bodies, industries, and communities. Striking a balance between effective firefighting practices and mitigating the unintended aftermath of AFFF foam is essential to ensure a sustainable future.
