Health-based TTHM: a health-based violation (a contaminant recorded above the limit the EPA tracks), recorded 8 times between October 2023 and January 2024. The EPA record lists a level of 0.081 MG/L; the limit (MCL) is 0.08 MG/L. EPA records do not show all of these as returned to compliance.

What this means

A health-based violation means a contaminant was recorded above the limit the EPA tracks for it. A monitoring or reporting violation means a required test or report was late or missed — not that a contaminant was measured above a limit. “Returned to compliance” means the EPA recorded the issue as resolved.
