“The most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials.” Rachel Carson, Silent Spring
Introduction
Per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” are man-made synthetic compounds widely used since the 1940s in products like firefighting foams, non-stick cookware, and water-repellent for their resistance to heat, water, and oil.
Their durable chemical structure renders them highly resistant to degradation, leading to their accumulation in the environment and living organisms has raised significant concerns about contamination, particularly around military installations where PFAS-containing firefighting foams have been extensively used.
This article delves into the environmental and health impacts of PFAS contamination stemming from military bases.
Environmental Impact of PFAS Contamination
Contamination of Water Sources on Military Bases
Military bases have historically utilized aqueous film-forming foams (AFFF) containing PFAS for firefighting training and emergency responses. This practice has led to significant environmental impacts including the contamination of groundwater and surface water sources.
As of August 2023, PFAS have been detected in drinking water and groundwater at 455 military sites, with potential contamination at an additional 255 sites, totaling 710 affected locations.
Plumes of toxic PFAS from at least 245 U.S. military bases are contaminating or threatening to pollute drinking water sources.
In areas like Oscoda, Michigan, PFAS contamination from nearby air force bases has severely impacted local wildlife, including popular hunting and fishing spots.
Recent studies have unveiled alarming levels of PFAS contamination in wildlife near military installations, raising concerns about the broader ecological and human health implications.
For instance, plumes of toxic PFAS have been identified flowing from at least 245 U.S. military bases, threatening drinking water supplies for nearby communities
Environmental Impact and Bioaccumulation in Wildlife
PFAS contamination extends beyond water sources, affecting wildlife and ecosystems through bioaccumulation.
PFAS have been detected in various wildlife species, leading to concerns about bioaccumulation and potential health effects on animals.
In the United States, several military installations have been identified with PFAS contamination, primarily due to the use of firefighting foams containing these chemicals.
At Holloman Air Force Base in New Mexico, studies revealed extraordinarily high levels of PFAS in both aquatic and terrestrial species. These findings indicate that PFAS can persist in ecosystems for decades, posing long-term risks to wildlife health.
In Albuquerque, New Mexico, state environmental regulators and health officials have issued warnings to hunters following the detection of high PFAS concentrations in wildlife near Holloman Air Force Base.
The New Mexico Environment Department (NMED) reported that samples from the Holloman Lake area exhibit some of the highest PFAS concentrations ever documented globally. Notably, a kangaroo rat from this region showed unprecedented levels of contamination.
Moreover, samples from birds, small mammals, and plants in the vicinity revealed some of the highest PFAS levels recorded globally. The contamination is linked to a lake utilized as a wastewater reservoir by the base, posing risks to migratory birds and individuals consuming waterfowl from the area, highlighting the broader environmental and public health implications of PFAS pollution from military
Soil Contamination
PFAS compounds can infiltrate soil, leading to direct contact risks for humans and facilitating further spread into groundwater and surface water. The Wisconsin Department of Natural Resources highlights that soil contamination by PFAS may pose significant environmental challenges, necessitating comprehensive remediation efforts.
Health Impacts of PFAS Exposure
Human Health Risks
PFAS enduring presence in the environment and their exposure have been linked to a variety of adverse health effects. The Agency for Toxic Substances and Disease Registry (ATSDR) identifies several potential outcomes, including:
- Increases in cholesterol levels.
- Liver enzyme alterations.
- Reduced vaccine response.
- Pregnancy-induced hypertension.
- Increased risk of kidney and testicular cancers.
Additionally, the Environmental Protection Agency (EPA) notes that PFAS exposure can lead to reproductive effects such as decreased fertility, developmental delays in children, and interference with natural hormones.
Moreover, exposure to PFAS has been linked to several adverse health outcomes, including:
- Cancer: Studies have identified associations between PFAS exposure and increased risks of certain cancers, such as testicular and kidney cancer.
- Thyroid Disorders: PFAS can interfere with thyroid hormone production, leading to conditions like hypothyroidism.
- Immune System Effects: These substances may impair immune responses, potentially reducing vaccine efficacy and increasing susceptibility to infections.
- Reproductive Issues: PFAS exposure has been associated with decreased fertility, developmental delays in children, and complications during pregnancy, including preeclampsia.
Community Health Concerns
Communities surrounding military bases are particularly vulnerable to PFAS exposure. In Oscoda, Michigan, the use of AFFF at a nearby air force base led to significant PFAS contamination.
Consequently, local wildlife, including deer and fish, exhibited high PFAS levels, prompting “Do Not Eat” advisories to protect public health.
Regulatory and Remediation Efforts
Department of Defense Initiatives
The Department of Defense (DoD) has acknowledged the widespread PFAS contamination across military installations and is actively investigating the extent of this issue. Efforts are underway to identify affected sites and implement appropriate cleanup actions to mitigate further environmental and health risks.
Environmental Working Group Findings
The Environmental Working Group (EWG) has identified over 700 U.S. military sites with known or suspected PFAS discharges, primarily from the use of PFAS-based firefighting foams. This extensive contamination underscores the need for comprehensive regulatory measures and remediation strategies to address the persistent environmental and health challenges posed by PFAS.
PFAS: From Firefighting to Environmental Persistence
PFAS have been widely used in firefighting foams employed by the DoD. This has led to significant environmental contamination at numerous military installations across the United States.
To deepen our understanding of these contaminations at military bases, we should consider the following questions as to:
- How have PFAS, commonly found in firefighting foams, transitioned from essential safety tools to pervasive environmental contaminants affecting wildlife near military installations?
- What mechanisms allow PFAS to persist in ecosystems surrounding military bases, leading to bioaccumulation in local fauna?
- In what ways does the presence of PFAS in wildlife near military sites pose potential risks to human health, particularly for communities relying on these areas for hunting and fishing?
- What strategies are currently employed to monitor and mitigate PFAS contamination in environments adjacent to military facilities, and how effective are these measures in protecting both wildlife and human populations?
- How does the bioaccumulation of PFAS in wildlife near military bases reflect on the broader implications of chemical management policies and environmental stewardship within defense sectors?
By exploring these questions, we can gain a comprehensive understanding of the factors contributing to the impact of PFAS on wildlife and human health in and around the DoD installations’ landscape of the United States.
Legal and Regulatory Actions
The discovery of high PFAS levels near a military installation raises pressing legal and environmental questions:
- Responsibility and Remediation: What obligations do military and governmental agencies have in addressing contamination originating from their operations?
- Public Health Measures: How can authorities effectively monitor and mitigate the health impacts on communities reliant on local wildlife for sustenance?
- Environmental Protection: What strategies are in place to prevent further environmental degradation and protect vulnerable ecosystems from persistent chemical pollutants?
The widespread detection of PFAS has prompted legal and regulatory scrutiny. In Maine, a significant spill of PFAS-containing firefighting foam at a former U.S. Navy base led to concerns about water contamination and the adequacy of state responses. Public health advocates have called for more transparent reporting and extensive testing to address potential exposure.
Scientific and Policy Implications
This situation highlights the need for comprehensive scientific research to understand PFAS’s long-term ecological and health effects. It also calls for robust policy interventions to regulate and remediate environmental contaminants, ensuring the safety and well-being of affected communities.
Conclusion
PFAS contamination originating from military bases presents significant environmental and public health challenges. The unprecedented PFAS contamination near Holloman Air Force Base serves as a critical case study, prompting reflection on our environmental stewardship and the measures necessary to safeguard public health against enduring chemical pollutants.
The persistence and bioaccumulative nature of these substances necessitate coordinated efforts from government agencies, military authorities, and communities to address contamination, implement effective remediation strategies, and proactive monitoring to protect both ecosystems and human communities from the enduring impacts of “Forever chemicals.”
