Horace, ND tap water

About 40% of Horace is inside a utility's service area. Homes outside it likely use private wells, which no utility tests.

Disinfectant

Chloramine

Utility water here is treated with chloramine. Unlike chlorine, it doesn't gas off when water sits out, and many pitcher and fridge filters aren't rated to remove it. Conditioners that list chloramine on the label break it apart, which frees a little ammonia. Some utilities switch to plain chlorine for a few weeks a year. Private wells aren't treated by a utility, so there's no chlorine or chloramine unless a treatment system adds it.
