On September 10, an incident at Temescal Pool exposed swimmers in the pool to chemical changes in the water during a privately-hosted swim program. A number of swimmers reported coughing with breathing difficulty. We are deeply sorry to the swimmers who were affected by this incident. Individuals who use a City pool expect and deserve a safe environment. Temescal Pool has been temporarily closed, and the City is conducting an investigation and implementing operational changes necessary to help prevent a similar incident from occurring again.
Additional mandatory training for City staff will be conducted prior to the pool being reopened. This retraining instructs that no changes to the circulation system or chemical controllers will be made while the swimming pool is in active use. We are working with the private swim program operators to reach out to all individuals who were participating in pool activities on the day of this incident to ensure they receive appropriate information and follow-up.
Temescal Pool remains closed pending the completion of scheduled pool equipment maintenance. The City will provide an additional update within one week from today.
