TTHM results

MS0630037 , Truelight Redevelopment GRP #2

16 samples have been analysed for TTHM at Truelight Redevelopment GRP #2.

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.

Showing samples collected between September 26, 2024 and September 26, 2026. That is this page’s default, not a limit on what the agency records.

Every TTHM result

The table below lists 1–10 of 16 samples, newest first — collected October 23, 2024 to October 12, 2025.

10 TTHM results from the 10 samples listed here: 4 detected, 6 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 The location on record identifies a private home, and we do not publish those.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.

TTHM results for Truelight Redevelopment GRP #2, from 1 to 10 of 16 samples shown analysed for it, newest first. This view leaves out other analytes on the same samples. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
