How do I know if I have good tap water?

You can likely find info online. In San Francisco we get information in the mail once a year. Probably because they want to brag about how good it is :)

I'm not sure why the smiley face, I have received the same "bragging" letter in a midwest state and a state north of San Francisco. Lots of places in US have good (or should I say standard) water.

And that’s great! I never implied San Francisco is the only place with high water quality.

I’m not talking about “standard” water though. San Francisco gets water from snowmelt so it has noticeably less contaminants than most water supplies. It routinely ranks among the top few water sources in the United States

"You guys have the best water that we tested. Period," Snyder said of San Francisco's drinking water. "I don't think we've ever tested drinking water that didn't have any of our target compounds in it."

I don't know about "good," but it's always money well spent to get a test kit from the home store (Home Depot and Lowes both sell them for $20-$30). Sometimes you can have an issue caused by your home that has nothing to do with the public supply.

Knew one person who found out his sewage pipes were somehow mingling with his fresh water ones this way. How that even happens, I do not know...

There should be a website that tells you for your current GPS location the quality of the tap water.
