- Source and quality

- Contaminants
- In public water systems nationwide, including San Francisco, standard testing looks for contaminants such as disinfectants byproducts, metals, microbial indicators, and other regulated substances. The city’s reports indicate compliance with drinking-water standards, with no PFAS detected above regulatory limits in the most recent comprehensive checks. As with any municipal system, occasional advisories or maintenance-related notes may occur, but routine drinking water remains within safe limits. [Annual water quality reports]
- Practical considerations
- Some individuals with specific plumbing concerns or highly sensitive health conditions may prefer using a filter or letting water run briefly before use, but this is not typically required for the general population. If there are ever advisories or service outages, the water utility will issue guidance through official channels. [City guidance and advisories]

They provide detailed data on testing, contaminants, and compliance, and are the authoritative source for San Francisco tap-water safety. [Official water quality resources]
Bottom line: drinking San Francisco tap water is considered safe and compliant with regulatory standards. If you have particular health considerations or concerns about plumbing in your building, you may choose to use a filter or run the tap for a moment before filling your glass, but this is optional for most residents.
