Chemical and radiological sample results

MS0240049 , Keesler Air Force Base

48 of the 76 analytes this system has been tested for have been detected at least once, across 1,097 samples on record.

The other 28 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 1,097 samples on record, detections range from June 16, 1995 to July 28, 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.

Every analyte ever detected for Keesler Air Force Base, 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 51–55 of 55 samples, newest first — collected November 19, 2024 to February 10, 2025. The summary above covers all 55.

33 results from the 5 samples listed here: 0 detected, 33 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 Keesler Air Force Base, every result from 51 to 55 of 55 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
