Water hardness in Benicia measures 182 mg/L β classified as hard.
Benicia's hard supply reflects the Solano County north Bay Area Sacramento River blend's calcareous-moderate character. The North Bay Aqueduct delivers Sacramento River supply to Benicia with limited softening, producing the hard 182 mg/L.
At 182 mg/L, Benicia residents face regular hard water challenges. Monthly descaling and water softeners are recommended. Benicia Water Utility consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
