Chemical and radiological sample results

MS0070004 , City of Calhoun City

25 of the 59 analytes this system has been tested for have been detected at least once, across 354 samples on record.

The other 34 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 354 samples on record, detections range from December 20, 1993 to April 29, 2026. These figures cover the whole record; the list of samples further down is narrowed.

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 Calhoun City, 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 21–21 of 21 samples, newest first — collected December 9, 2024 to December 9, 2024. The summary above covers all 21.

1 result from the 1 sample listed here: 1 detected, 0 not detected. 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 Calhoun City, every result from 21 to 21 of 21 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
