Chemical and radiological sample results

MS0180011 , City of Petal

29 of the 107 analytes this system has been tested for have been detected at least once, across 823 samples on record.

The other 78 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 823 samples on record, detections range from October 20, 1992 to July 1, 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.

Every analyte ever detected for City of Petal, 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 101–110 of 823 samples, newest first — collected March 22, 2021 to July 7, 2021. The summary above covers all 823.

55 results from the 10 samples listed here: 6 detected, 49 not detected. Across the whole record it is 713 of 3,987. 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 Petal, every result from 101 to 110 of 823 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
