Chemical and radiological sample results

MS0180008 , City of Hattiesburg

44 of the 76 analytes this system has been tested for have been detected at least once, across 1,045 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 1,045 samples on record, detections range from July 21, 1992 to December 1, 2025. These figures cover the whole record; the list of samples further down is narrowed.

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 Hattiesburg, 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 11–20 of 20 samples, newest first — collected February 19, 2025 to February 19, 2025. The summary above covers all 20.

70 results from the 10 samples listed here: 13 detected, 57 not detected. 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 Hattiesburg, every result from 11 to 20 of 20 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
