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.

Every TTHM result

The table below lists 11–20 of 51 samples, newest first — collected August 15, 2023 to July 1, 2024.

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 The location on record identifies a private home, and we do not publish those.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 City of Bay St Louis, from 11 to 20 of 51 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.
