What the EPA has on record, by system
Coffey Pws
166 served · groundwater · PWSID MO1010179 - Health-based TTHM: a health-based violation (a contaminant recorded above the limit the EPA tracks), recorded 7 times between January 2016 and July 2017. The EPA record lists a level of 103 UG/L; the limit (MCL) is 80 UG/L. All have since returned to compliance, per EPA records.

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.
