As part of the Ventura County Ocean Water Quality Monitoring Program, the Environmental Health Division is
providing the following precautionary information for the public. Rainfall that is significant enough to result in
runoff can flow into storm drains, channels, creeks, and rivers that empty onto the beaches of Ventura
County. In general, 0.2 inches (2 tenths of an inch) of rainfall may be enough to create significant runoff
There is a potential for storm water runoff to carry disease causing bacteria to the beaches and into the
ocean water. In addition, storm water runoff can transport physical hazards such as partially submerged tree
limbs and logs into the ocean that could result in serious physical injury. Contact with this runoff water will
result in an increased risk to human health and should be avoided for at least 72 hours after all rainfall activity
As a result of the recent rainfall, the public is advised to avoid body contact with all storm water runoff and
ocean water at all Ventura County beaches. Any items that may have come in contact with runoff or ocean
water should also be avoided. If contact occurs, wash thoroughly with soap and water.
Any shellfish on or from Ventura County beaches may have also been exposed to this contamination and
should not be eaten.
This advisory will remain in effect for 72 hours (3 days) after all rainfall has ended.
Bacteriological sample results for specific beaches are also available on the Environmental Health Division
hotline (recorded information), 805/662-6555, and on the Division's Web page at:
