TTHM results
MS0140051 , Moore Bayou W/A #2
59 samples have been analysed for TTHM at Moore Bayou W/A #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.
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 41–50 of 59 samples, newest first — collected August 25, 2008 to October 5, 2009.
10 TTHM results from the 10 samples listed here: 10 detected, 0 not detected. Those samples also carried 40 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 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 The location on record identifies a private home, and we do not publish those.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.

| 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 Apr 30, 2009, sampling point MRT000 | TTHM 2950 EPA method 524.2 | Apr 1, 2009 – Jun 30, 2009 |
