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.
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 321–330 of 354 samples, newest first — collected January 24, 1994 to January 24, 1994. The summary above covers all 354.
20 results from the 10 samples listed here: 12 detected, 8 not detected. Across the whole record it is 535 of 1,511. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
