Chemical and radiological sample results

MS0240036 , City of Biloxi-French

44 of the 75 analytes this system has been tested for have been detected at least once, across 420 samples on record.

The other 31 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 420 samples on record, detections range from July 20, 1993 to November 12, 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 Biloxi-French, 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 11–14 of 14 samples, newest first — collected February 11, 2025 to February 11, 2025. The summary above covers all 14.

30 results from the 4 samples listed here: 0 detected, 30 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 Biloxi-French, every result from 11 to 14 of 14 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
