Read, Watch or Listen

Hazardous materials crews in Garden Grove, California began removing neutralized chemical waste from the GKN Aerospace facility on Monday, June 29, 2026, following a major industrial emergency that prompted mass evacuations in Orange County. The operation, led jointly by the Orange County Health Care Agency, the South Coast Air Quality Management District and GKN Aerospace, focuses on safely extracting methyl methacrylate, a volatile and flammable liquid used in plastics and aerospace production. The waste has been chemically neutralized in two storage tanks, but authorities say physically removing it remains complex and requires strict environmental and public safety controls after last month’s evacuation of about 50,000 residents.
