Chemical and radiological sample results

MS0250008 , City of Jackson

33 of the 108 analytes this system has been tested for have been detected at least once, across 4,736 samples on record.

The other 75 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 4,736 samples on record, detections range from May 22, 1992 to August 24, 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.

Every analyte ever detected for City of Jackson, 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 1,781–1,790 of 4,736 samples, newest first — collected March 18, 2020 to April 22, 2020. The summary above covers all 4,736.

75 results from the 10 samples listed here: 22 detected, 53 not detected. Across the whole record it is 8,337 of 13,832. 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 City of Jackson, every result from 1,781 to 1,790 of 4,736 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
