Chemical and radiological sample results
MS0300147 , Naval Station-Pascagoula
31 of the 53 analytes this system has been tested for have been detected at least once, across 473 samples on record.
The other 22 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 473 samples on record, detections range from September 22, 2003 to March 17, 2026. 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 39 samples, newest first — collected September 24, 2025 to March 17, 2026. The summary above covers all 39.
15 results from the 10 samples listed here: 11 detected, 4 not detected. Across the whole record it is 795 of 3,715. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
