What is this lawsuit about?

The City of Kansas City, Missouri is filing a lawsuit against manufacturers of Aqueous Film-Forming Foam (AFFF)—a type of firefighting foam that contains PFAS, a class of harmful chemicals known as “forever chemicals.” The City is seeking to recover the costs of environmental testing, cleanup, and public health protections associated with PFAS contamination at City-owned facilities, including the airport and water system infrastructure.

What are PFAS and why are they called “forever chemicals”?

PFAS (Per- and Polyfluoroalkyl Substances) are synthetic chemicals used in a wide range of industrial and consumer products because they resist heat, oil, and water. They’re called “forever chemicals” because they do not break down naturally in the environment and can accumulate in soil, water, and the human body over time.

What is AFFF and how was it used in Kansas City?

Aqueous Film-Forming Foam (AFFF) is a firefighting foam used to suppress fuel-based fires, often at airports and industrial sites. It was historically used at Kansas City’s airport and other facilities before its risks were widely understood. PFAS from AFFF can seep into the ground and contaminate water sources.

Why is Kansas City filing this lawsuit now?

New research, regulations, and federal guidance have highlighted the serious health and environmental risks of PFAS. Many cities across the country are filing lawsuits to hold chemical manufacturers accountable for pollution caused by AFFF. Kansas City is joining this effort to protect public health and to avoid placing the financial burden of cleanup solely on local taxpayers.

What departments or areas are impacted?

The City is investigating PFAS contamination related to historic use of AFFF at the Kansas City Aviation Department (KCAD) and within KC Water systems. The full extent of contamination is still being studied.

Is my drinking water safe?

At this time, KC Water continues to meet or exceed all state and federal safety standards for drinking water. The City is committed to transparency and will share updates if that changes. This lawsuit is a proactive step to ensure long-term protection of water quality and public health.

What are the health risks associated with PFAS exposure?

According to the U.S. EPA and other health authorities, long-term exposure to certain PFAS may be linked to:

• Increased cancer risk
• Liver and kidney damage
• Immune system suppression
• Hormonal disruption
• Developmental issues in infants and children

What is the City hoping to achieve through the lawsuit?

Kansas City is seeking to:

• Hold chemical manufacturers accountable
• Recover the costs of environmental testing and remediation
• Ensure clean water and safe soil for future generations
• Avoid passing the cost of long-term cleanup onto Kansas City residents

Will this affect City operations or services?

No. This lawsuit is not expected to impact day-to-day City operations. It is part of a long-term strategy to protect public resources and public health.

Where can I find more information or follow updates?

The City will maintain a dedicated page with updates, background, and contact info.
