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.

The most recent samples, result by result
The table below lists 2,051–2,060 of 4,736 samples, newest first — collected May 3, 2019 to August 5, 2019. The summary above covers all 4,736.
27 results from the 10 samples listed here: 7 detected, 20 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.
We withheld the location of 1 sampling point below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.
