On November 10, 2017, Santa Rosa Water issued a Do-Not-Drink and Do-Not-Boil advisory for 13 homes in the Fountaingrove area. This advisory went into effect after elevated levels of benzene were detected in parts of the drinking water system affected by the distribution system, (see green-lined area on the map). The advisory will remain in place until further notice.

Residents impacted by the Do-Not-Drink and Do-Not-Boil advisory for 13 homes in the Fountaingrove area were notified in person and/or with door hangers and advised to not to consume tap water until further notice. This includes drinking, cooking, or brushing teeth.

Benzene and Drinking Water

Santa Rosa Water is required to monitor your drinking water for benzene and ensure levels remain below the California drinking water standard, which is 1.0 part per billion. Water quality testing after the fires continues to show that there was no benzene in the source water and through most neighborhoods in the City of Santa Rosa.  

However, post-fire samples from one neighborhood in Fountaingrove contained benzene. The water pipes in this neighborhood were isolated by closing valves, to ensure that the contamination did not spread to other neighborhoods.Santa Rosa’s scientist and engineers are working hard to determine the source of the contamination and remove it. As of today, the source or sources have not been identified, but indications are that benzene contamination is related to the fires.

We have been, and are continuing to conduct extensive sampling to make sure the benzene-contaminated area is isolated from the rest of the system. We have been communicating with the California Division of Drinking Water about our actions related to the benzene contamination.

For information on health risks associated with benzene, please visit the California Office of Environmental Health Hazard Assessment (OEHHA) website:  https://oehha.ca.gov/water/chemicals/benzene.

Restoring Water Quality  

Santa Rosa Water has isolated the affected portion of the water system to prevent contamination into other areas. Our team is actively flushing, cleaning, and replacing portions of the system EF9A9471to remove the contamination. This includes monitoring progress by collecting frequent water samples and sending them to our State-certified environmental laboratory for analysis.

Until Santa Rosa’s scientists and engineers determine the source of the contaminant and remove it, Santa Rosa Water will continue to have a drinking water advisory in place for the 13 affected homes in Fountaingrove.
