SAN LUIS OBISPO — A sewage spill at the San Luis Obispo Wastewater Treatment Plant released approximately 7,800 gallons of partially treated wastewater into San Luis Obispo Creek, significantly lower than the initially estimated 50,000 gallons. The spill, caused by a storm surge event, was mitigated within 20 minutes.

Environmental Health Services advises beachgoers to avoid ocean water at the creek outfall at Avila Beach and surrounding areas until water quality samples confirm safe bacteria levels. Officials warn that storm runoff can carry harmful pathogens, posing health risks such as skin infections, gastrointestinal issues, and respiratory problems.

The public is urged to avoid ocean water contact during and for at least three days after heavy rainfall. For updates on water quality, visit SurfSafeSLO.org or call the Ocean Water Monitoring Program hotline at (805) 788-3411
