Chemical and radiological sample results
MS0520024 , Shuqualak-Butler W/A
23 of the 57 analytes this system has been tested for have been detected at least once, across 135 samples on record.
The other 34 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 135 samples on record, detections range from March 17, 2004 to March 27, 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.

The most recent samples, result by result
The 4 samples collected between September 25, 2024 and September 25, 2026 are listed below, newest first.
16 results from the 4 samples listed here: 7 detected, 9 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
