Chemical and radiological sample results

MS0100002 , Choctaw Water Assn

12 of the 26 analytes this system has been tested for have been detected at least once, across 212 samples on record.

The other 14 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 212 samples on record, detections range from December 7, 1993 to September 16, 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 Choctaw Water 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 81–90 of 212 samples, newest first — collected October 6, 2008 to October 6, 2008. The summary above covers all 212.

20 results from the 10 samples listed here: 16 detected, 4 not detected. Across the whole record it is 276 of 465. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Choctaw Water Assn, every result from 81 to 90 of 212 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
