Chemical and radiological sample results
MS0640009 , Okatoma Water Association #1
29 of the 98 analytes this system has been tested for have been detected at least once, across 440 samples on record.
The other 69 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 440 samples on record, detections range from October 22, 2003 to July 22, 2026. 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.

The most recent samples, result by result
The table below lists 371–380 of 440 samples, newest first — collected July 6, 2010 to August 10, 2010. The summary above covers all 440.
27 results from the 10 samples listed here: 16 detected, 11 not detected. Across the whole record it is 591 of 1,989. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

| 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 Jul 6, 2010, sampling point MRT000 | Total Haloacetic Acids (Haa5) 2456 | Jan 1, 2008 – Dec 31, 2010 |
