Why be concerned about PFAS Chemicals?
|
PFAS (per- and polyfluoroalkyl substances) are a group of synthetic chemicals known for their water- and grease-resistant properties, which make them useful in various applications, including firefighting foams. Airports are a significant concern regarding PFAS because these chemicals are commonly used in aqueous film-forming foams (AFFF) for fire suppression.

The key reasons why PFAS chemicals from airports should be a concern include:
- Environmental Contamination: PFAS can persist in the environment for a long time due to their stable chemical structure. When AFFF is used during firefighting drills or emergencies, or when it accidentally leaks, it can contaminate soil and groundwater around airports. This contamination can spread to surrounding areas and affect larger ecosystems.
- Health Risks: PFAS have been linked to various health issues in humans, including increased risks of cancer (such as kidney and liver cancers), liver damage, thyroid disease, and developmental problems in children. Prolonged exposure to PFAS through contaminated water or food can pose serious health risks to local communities.
- Regulatory Challenges: PFAS are often referred to as "forever chemicals" due to their persistence and difficulty in breaking down. This makes remediation efforts costly and complex. Many regions are still grappling with how to regulate and manage PFAS contamination effectively, leading to ongoing environmental and public health concerns.
- Economic Impact: Contaminated water supplies and land can lead to significant economic costs for cleanup and health care. Airports may face financial burdens related to managing PFAS contamination, including regulatory compliance, cleanup costs, and potential lawsuits.
