Earlier today, the Santa Ana Unified School District identified a chlorine release from a storage tank in the pool area at Segerstrom High School. A portion of the chlorine release entered the local storm drain system.
The District immediately notified the City of Santa Ana, and the two agencies initiated a coordinated response. Working together with a licensed environmental response contractor, emergency crews quickly isolated the affected area and began containment, recovery, and cleanup operations.
As part of the response, specialized crews flushed the affected storm drain line and vacuumed the resulting water and residual material for proper collection and disposal in accordance with applicable environmental regulations. The Santa Ana Unified School District and the City of Santa Ana worked alongside the contractor throughout the response to support these efforts.
Response teams also evaluated whether any of the released material had reached the Orange County flood control channel. The assessment confirmed that the release was successfully contained within the local storm drain system and did not reach the County flood control channel.
At this time, there is no ongoing chlorine release, and officials have confirmed there is no danger to the surrounding community. Cleanup activities will continue until response officials determine that all affected portions of the storm drain system have been properly addressed. The District and the City will also evaluate the incident to identify any additional measures that may help prevent similar occurrences in the future.
The City of Santa Ana and the Santa Ana Unified School District appreciate the prompt and coordinated efforts of District staff, City personnel, and the environmental response contractor. Protecting public health, public safety, and the environment remains our highest priority, and we are committed to keeping the community informed should additional information become available.
