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.
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 91–100 of 420 samples, newest first — collected September 24, 2019 to April 20, 2020. The summary above covers all 420.
37 results from the 10 samples listed here: 14 detected, 23 not detected. Across the whole record it is 572 of 2,707. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
