Chemical and radiological sample results
MS0110005 , Town of Port Gibson
41 of the 115 analytes this system has been tested for have been detected at least once, across 783 samples on record.
The other 74 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 783 samples on record, detections range from May 19, 1992 to December 22, 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 431–440 of 783 samples, newest first — collected November 5, 2013 to April 23, 2014. The summary above covers all 783.
40 results from the 10 samples listed here: 6 detected, 34 not detected. Across the whole record it is 1,190 of 2,059. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
