TTHM results
MS0100017 , Union W/A
41 samples have been analysed for TTHM at Union W/A.
This is one analyte out of the system’s whole record. For what has ever been detected here, and when, see all chemical and radiological results; for everything the system is tested for, see the analyte list.
What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.
No date range is applied: this list draws on every sample on record. Show the last two years only.
Every TTHM result
The table below lists 1–10 of 41 samples, newest first — collected January 13, 2021 to March 17, 2025.
10 TTHM results from the 10 samples listed here: 5 detected, 5 not detected.
We withheld the location of 4 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.
