VENTURA COUNTY, California – A fast-moving wildfire in Simi Valley has burned more than 2,140 acres and advanced to within a quarter mile of the heavily contaminated Santa Susana Field Laboratory, one of the nation’s most polluted former nuclear and rocket testing sites. The Sandy Fire began on the morning of May 18, 2026, near Sandy Avenue, with investigators probing reports that a tractor striking a rock may have sparked the blaze. By Thursday, May 22, containment had reached 40 percent. Authorities ordered mandatory evacuations for over 43,700 residents, closed all Simi Valley Unified schools through Memorial Day, and deployed more than 750 firefighters supported by air tankers and helicopters. Governor Gavin Newsom secured a FEMA Fire Management Assistance Grant to bolster firefighting resources as air quality alerts spread across Southern California.
