Chemical and radiological sample results

MS0680013 , West Tallahatchie Utl Assn

43 of the 75 analytes this system has been tested for have been detected at least once, across 324 samples on record.

The other 32 were tested for and never found. An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.

Across all 324 samples on record, detections range from October 27, 2003 to April 1, 2025. These figures cover the whole record.

What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.

What has been detected, ever

Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

Every analyte ever detected for West Tallahatchie Utl Assn, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 271–280 of 324 samples, newest first — collected October 12, 2005 to May 25, 2006. The summary above covers all 324.

60 results from the 10 samples listed here: 16 detected, 44 not detected. Across the whole record it is 459 of 2,026. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Units in this table

TTHM is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

Chemical and radiological sample results for West Tallahatchie Utl Assn, every result from 271 to 280 of 324 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.

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.
