TTHM results
MS0370010 , Town of Sumrall
10 samples have been analysed for TTHM at Town of Sumrall.
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
All 10 samples analysed for this analyte are listed below, newest first. No date range is applied.
10 TTHM results from the 10 samples listed here: 7 detected, 3 not detected. Those samples also carried 30 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.

| 0 This result is recorded as a detection, and the figure the agency wrote — "0.00" — is zero to the precision it was written to. Read the zero as "smaller than the written figure resolves", not as "none present". SDWIS holds a separate numeric concentration that Drinking Water Watch does not publish, so this endpoint does not carry it either; no more precise magnitude is available here. The agency recorded a value but no unit of measure for it. The unit is NOT inferable from the analyte: many analytes are reported in more than one unit — TTHM and HAA5 in both MG/L and UG/L — so there is no per-analyte default to fall back on. The number is published as it stands and must not be compared to a limit. The agency recorded which kind of limit this result was below, but stored 0.000000000 as the limit itself, which is not a level. The type is published and the value is null. What the limit was is not on record. Whether the result was a detection is a separate column: read resultType. , sample collected Sep 22, 2009, sampling point MRT000 | TTHM 2950 EPA method 524.2 | Jan 1, 2008 – Dec 31, 2010 |
