Emergency

Residential Well Water Users

En español »

Following two years of drought, groundwater tables are dropping in some parts of Sonoma County. As a result, some wells may be experiencing increases in contaminants and/or declines in the amount of water they produce. Well owners are personally responsible for testing their wells to ensure their water is safe.
