TTHM results
MS0540067 , Concord-Macedonia W/A
12 samples have been analysed for TTHM at Concord-Macedonia 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 12 samples, newest first — collected September 27, 2006 to February 27, 2024.
10 TTHM results from the 10 samples listed here: 8 detected, 2 not detected. Those samples also carried 24 results for other analytes, which are on the full results page.
Units in this table
TTHM is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
We withheld the location of 1 sampling point 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 The location on record identifies a private home, and we do not publish those.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.
