TTHM results

MS0140052 , Moore Bayou W/A #3

70 samples have been analysed for TTHM at Moore Bayou W/A #3.

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 70 samples, newest first — collected October 11, 2023 to March 26, 2025.

10 TTHM results from the 10 samples listed here: 10 detected, 0 not detected.

We withheld the location of 2 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 The location on record identifies a private home, and we do not publish those.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 Moore Bayou W/A #3, from 1 to 10 of 70 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.
