Berkeley tap water quality
Berkeley ZIPs usually map to East Bay MUD. Reports are educational ZIP→utility matches from CA SDWIS extracts.
Honest framing: This is not a citywide water score. We match your ZIP to a public water system using CA service-area data where available. Contaminant lists are curated detections — non-detects are omitted. Educational only — not medical advice, not a faucet lab test, and not affiliated with EWG or any utility.
