Provo, UT tap water
Supplied by Provo City. Here's what its water means for your fish.
Disinfectant

Your water is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it.
Safety for fish and shrimp

Not detected in testing, so any nitrite in your tank comes from the tank itself.
From EPA monitoring data (2016).
Nitrate (NO₃)
Up to 2.2 ppm (Low)

Copper at home taps (first draw)
Up to 0.3 ppm (Worth knowing)
The 90th percentile of first-draw samples from homes: water that sat in household pipes for at least six hours.
