Chemical and radiological sample results
MS0170018 , City of Southaven
30 of the 60 analytes this system has been tested for have been detected at least once, across 839 samples on record.
The other 30 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 839 samples on record, detections range from July 20, 1992 to June 22, 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 161–170 of 839 samples, newest first — collected May 13, 2019 to January 22, 2020. The summary above covers all 839.
20 results from the 10 samples listed here: 14 detected, 6 not detected. Across the whole record it is 1,052 of 3,017. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
