Tyhee, ID tap water
About 46% of Tyhee is inside a utility's service area. Homes outside it likely use private wells, which no utility tests.
Disinfectant
Not confirmed
We couldn't confirm how utility water here is disinfected. US utilities use chlorine or chloramine, and chloramine doesn't gas off when water sits out. Private wells aren't treated by a utility, so there's no chlorine or chloramine unless a treatment system adds it.

Nitrite (NO₂)
Up to 0.72 ppm (Worth knowing)

Some nitrite shows up in this tap water, which can happen in chloramine systems, and it goes into the tank with each water change.
From EPA monitoring data (2018–2019).
Nitrate (NO₃)
