Sandy Fire Near Santa Susana Field Laboratory Prompts Air Quality Monitoring
The Sandy Fire, burning near the Santa Susana Field Laboratory in Ventura County, California, has raised concerns due to its proximity to a former nuclear test site. As of May 21, 2026, the fire has scorched 2,141 acres and is 30% contained. Firefighters are benefiting from lower winds and higher humidity, which have reduced the fire's intensity. Air quality monitoring has been deployed around the fire's perimeter to establish baseline data in case the fire advances into the contaminated area. The Santa Susana site, historically used for nuclear research and rocket engine testing, is undergoing environmental cleanup. Officials have stated that radiation levels at the site remain low and pose no significant health risks, even if the fire reaches the area.
