Chemical and radiological sample results

MS0040012 , Mississippi Water Company

11 of the 13 analytes this system has been tested for have been detected at least once, across 184 samples on record.

The other 2 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 184 samples on record, detections range from August 25, 1993 to December 19, 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 Mississippi Water Company, 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 111–120 of 184 samples, newest first — collected June 23, 1999 to June 27, 2000. The summary above covers all 184.

20 results from the 10 samples listed here: 7 detected, 13 not detected. Across the whole record it is 205 of 493. 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 Mississippi Water Company, every result from 111 to 120 of 184 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
