Total Trihalomethanes in Treasure Valley drinking water

43 of 67 systems that tested for it in the last 36 months detected it; 5 are above the limit, elevated, or an aesthetic issue. Total Trihalomethanes is a byproduct of disinfecting water with chlorine. Certified filters are in the list.

Compliance is on a locational running annual average across distribution sites, so single high samples do not by themselves mean a violation.
