Santa Rosa, CA – March 5, 2019 – The Sonoma County Health Officer declared a local health emergency Tuesday due to the scale of household hazardous waste (HHW) scattered along the water ways, roadsides, and on public and private properties after flooding in the County from last week’s rain storms.
The health emergency was proclaimed by Interim County Health Officer Dr. Karen Holbrook to highlight the potential risks to health and safety of residents from HHW in the areas of the County that were flooded.
The flooding and storm damage impacted an estimated 2,572 homes and businesses along the Russian River and low lying areas. The damage to these sites generated a large amount of HHW that must be addressed.
HHW cannot be disposed of in normal garbage or waste facilities. This material requires disposal at an authorized facility that processes hazardous waste.
To facilitate proper disposal, the County is asking residents to place their HHW on their property near the road. Trained staff will be collecting HHW from properties starting Tuesday, March 5, 2019.
Also, a special HHW collection will take place on Saturday, March 9, 2019.
