Orange County Residents Warned of Chemical Odors as GKN Aerospace Tank Cleanup Continues
Officials say air monitoring remains in place as crews remove the remaining chemical from a damaged tank that forced about 50,000 evacuations.
- Crews are draining the remaining methyl methacrylate from a damaged GKN Aerospace storage tank in Garden Grove through Friday, with Orange County health officials warning residents of "temporary, intermittent odors" during the process.
- Following a late-May cooling system failure, the tank became unstable and threatened a "boiling liquid expanding vapor explosion" , forcing an estimated 40,000 to 50,000 residents across Garden Grove and nearby Orange County communities to evacuate their homes.
- While officials noted the chemical has a "distinctive fruity or plastic-like odor," air monitoring consistently shows levels remain within safety thresholds. Residents may notice scents even when concentrations are well below levels associated with health concerns.
- GKN Aerospace pledged $4 million in community initiatives, allocating $3 million to the Orange County United Way's OC Community Resilience Fund to assist impacted residents. Dozens of residents have filed lawsuits citing financial strain from the evacuations.
- Garden Grove City Council members met on Thursday to discuss how to pursue accountability for the incident as cleanup continues. Officials from the Orange County Health Care Agency coordinate with federal environmental experts to ensure public safety throughout the operation.
