At certain times of year, naturally-occurring algae blooms may occur in Sweetwater Reservoir. Though they typically pose no public health risk, algae blooms have the potential to impact water taste and odor.
Sweetwater Authority may take proactive measures to apply an approved aquatic pesticide (copper sulfate) to Sweetwater Reservoir in order to control the taste and odor causing algae and lessen potential impacts. Applications are performed in an environmentally-safe manner and follow strict regulatory requirements.
If application of copper sulfate becomes necessary, the Authority will provide specific information on application site and timeline.
For more information regarding algae treatment and odor, please call Mark Hatcher (619-409-6813) or Juan Reyes (619-409-6826).
