In San Jose, California, residents can access drinking water quality test results through their water supplier, state drinking-water databases, and regional water agencies. This guide explains the official sources, who enforces drinking-water standards, how to request records or file a complaint, and practical steps to obtain test results for your address.

Where to find official test results

Most San Jose customers receive potable water from the local supplier for their area; the supplier publishes an annual Consumer Confidence Report (CCR) and posts water-quality summaries online. You can locate system-specific monitoring data through your supplier's water-quality page San Jose Water - Water Quality[1] or by searching the California State Water Resources Control Board27s Drinking Water Watch portal for system monitoring results and violations Drinking Water Watch[2]. Regional information and watershed-level monitoring is available from the Santa Clara Valley Water District Valley Water - Water Quality[3].

If you do not know your water supplier, check your utility bill or ask your landlord or homeowners association.
