In a significant move towards environmental sustainability, the Indianapolis Airport Authority has approved a transition to more eco-friendly firefighting foam, replacing older formulations that contain harmful "forever chemicals." This decision, made during the board meeting on April 18, 2025, aims to enhance the health and safety of firefighters while complying with evolving environmental regulations.

The airport's firefighting trucks, known as ARFF trucks, have historically used a specific type of foam that has been linked to long-lasting environmental contamination. The board discussed the need for an extensive cleaning process to remove residues of the old foam from the trucks. After evaluating various cleaning methods, the authority has chosen to work with CDM Smith, a leading expert in the field, to ensure the best technical results.

As part of the transition, the existing foam will either be repurposed for use by the U.S. military or destroyed through proper disposal methods. The fire department has expressed strong support for this change, recognizing the benefits of switching to safer chemical compositions. Training will be provided to firefighters to familiarize them with the new foam, which behaves differently in use.

In addition to the foam transition, the board also discussed an amendment for a one-month extension of a professional services agreement related to a hotel project, with a budget not exceeding $98,000. This agreement is expected to be finalized and presented at the next board meeting on May 16, 2025.

These decisions reflect the airport authority's commitment to improving safety and environmental standards, aligning with broader community goals for a healthier and more sustainable Indianapolis.
