Chemical and radiological sample results
MS0440018 , Columbus Air Force Base
10 of the 14 analytes this system has been tested for have been detected at least once, across 207 samples on record.
The other 4 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 207 samples on record, detections range from January 9, 2007 to October 28, 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 207 samples, newest first — collected July 22, 2015 to August 25, 2015. The summary above covers all 207.
24 results from the 10 samples listed here: 11 detected, 13 not detected. Across the whole record it is 332 of 536. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
