May chemical leak forced 13 schools to close

What happened

A volatile, highly flammable chemical tank at a Garden Grove aerospace facility prompted officials to close 13 GGUSD schools on May 22, 2026. The district says it shifted instruction primarily online; ten schools reopened after the evacuation zone was reduced, and the remaining three reopened May 27 after all evacuation orders were lifted.

Why it matters to families

The emergency disrupted instruction and school services across 13 campuses, and posed a potential safety threat to students and staff. The agenda describes a resolved May incident, not a current evacuation or closure.

The evidence

October 20 agenda item 6-A reports that a tank holding about 5,000–7,000 gallons of methyl methacrylate began heating at GKN Aerospace on May 21. At officials’ direction, 13 schools closed May 22; ten were cleared to reopen May 26, and Wakeham Elementary, Lawrence Elementary, and Alamitos Intermediate reopened May 27 after authorities lifted all evacuation orders. The district reports $182,410.68 in response costs and is asking the board to authorize applications for reimbursement; that authorization is proposed on the agenda, not an adopted outcome.
