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.

The most recent samples, result by result
The table below lists 1–10 of 20 samples, newest first — collected June 11, 2025 to February 11, 2026. The summary above covers all 20.
42 results from the 10 samples listed here: 11 detected, 31 not detected. Across the whole record it is 1,340 of 4,834. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
