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.

Every analyte ever detected for Town of Port Gibson, 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 491–500 of 783 samples, newest first — collected October 6, 2010 to August 10, 2011. The summary above covers all 783.

40 results from the 10 samples listed here: 10 detected, 30 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.

Chemical and radiological sample results for Town of Port Gibson, every result from 491 to 500 of 783 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
