Santa Rosa Water's Post-Fire Water Quality Investigation
On November 10, 2017, Santa Rosa Water issued a drinking water quality advisory for an isolated area of Fountaingrove when elevated levels of benzene were identified. To date, Santa Rosa Water has taken almost one thousand post-fire water quality samples to determine the source of contamination.
Santa Rosa Water is using this sampling data to drive our investigation. With the help of water quality experts from across the nation, including a forensic chemist, we are working diligently to find the source of contamination in order to resolve the issue as quickly as possible.
Inside the drinking water quality advisory area, we are finding the highest levels of benzene in investigative water samples taken from services to destroyed properties, but are also finding elevated levels in the water main and other components of the water system. Outside of the advisory area, water quality sampling continues to show no change in water quality.
