Supplied by Tri-City Jw&sa. Here's what its water means for your fish.

We couldn't confirm how your water is disinfected. US utilities use chlorine or chloramine, and chloramine doesn't gas off when water sits out.

Our data comes from public records and is still incomplete. Many utilities don't publish every number, so we're adding more all the time. Your city's range is a starting point: testing your own tap is the only way to know exactly what's in it.
