Case Study: Hamilton Sundstrand achieves successful vapor intrusion cleanup and class-action settlement with Sigler Communications

Hamilton Sundstrand settles $400M class-action for under $2M with Sigler Communications

Hamilton Sundstrand, an international aerospace manufacturer, faced a significant environmental challenge when chemical vapors from its Denver facility migrated into a nearby residential area. The company retained Sigler Communications to develop a community relations and communications strategy to inform and engage homeowners, officials, and the media about the required testing and remediation program.

Sigler Communications implemented a comprehensive seven-year program that included public information sessions, bilingual fact sheets, a 24-hour hotline, and liaison services. The efforts by Sigler Communications are credited with helping Hamilton Sundstrand successfully complete its cleanup and achieve a No Further Action status from regulators. Crucially, the communications strategy contributed to the settlement of a class-action lawsuit initially seeking over $400 million for less than $2 million.
