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.

Every analyte ever detected for City of Southaven, 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 451–460 of 839 samples, newest first — collected May 14, 2008 to February 24, 2009. The summary above covers all 839.

53 results from the 10 samples listed here: 10 detected, 43 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.

Units in this table

TTHM is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

Chemical and radiological sample results for City of Southaven, every result from 451 to 460 of 839 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
