Chemical and radiological sample results

MS0710006 , City of Iuka

15 of the 58 analytes this system has been tested for have been detected at least once, across 157 samples on record.

The other 43 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 157 samples on record, detections range from October 29, 2003 to September 9, 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 City of Iuka, 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 21–30 of 157 samples, newest first — collected October 18, 2022 to April 1, 2025. The summary above covers all 157.

33 results from the 10 samples listed here: 13 detected, 20 not detected. Across the whole record it is 177 of 617. 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 City of Iuka, every result from 21 to 30 of 157 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
