California drinking water
California water quality: reports first, filters second
California utilities publish annual CCRs that often list PFAS, nitrates in agricultural basins, and legacy solvents. Start with your utility PDF (or a certified well panel), then match filter class to the named contaminants — not to a generic “California water” myth.

Watch-fors
What households usually check
- PFAS detections on many urban systems
- nitrates in Central Valley ag regions
- legacy industrial solvents / VOCs in older industrial corridors
- hardness and chlorine taste on municipal supplies
Steps
A practical path
- 1Pull your utility’s latest Consumer Confidence Report (CCR) from the utility website or the EPA CCR finder.
- 2If you are on a private well, order a certified lab panel (coliform, nitrate, and any regional metals your county recommends).
- 3If PFAS or lead appear above your state’s guidance, compare pitcher vs RO shortlists where claims are labeled certified vs claims-only.
- 4Budget annual cartridge cost before you buy hardware — California hard water shortens carbon life.
