Plum Grove, TX tap water
About 36% of Plum Grove is inside a utility's service area. Homes outside it likely use private wells, which no utility tests.
Disinfectant
Chlorine
Utility water here is treated with chlorine. It slowly gases off from standing water, and any water conditioner removes it. Private wells aren't treated by a utility, so there's no chlorine or chloramine unless a treatment system adds it.
