Chemical and radiological sample results
MS0180011 , City of Petal
30 of the 107 analytes this system has been tested for have been detected at least once, across 826 samples on record.
The other 77 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 826 samples on record, detections range from October 20, 1992 to September 2, 2026. 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 521–530 of 826 samples, newest first — collected August 5, 2009 to September 23, 2009. The summary above covers all 826.
30 results from the 10 samples listed here: 24 detected, 6 not detected. Across the whole record it is 719 of 4,038. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
