Chemical and radiological sample results
MS0340001 , Calhoun Water Association
17 of the 54 analytes this system has been tested for have been detected at least once, across 297 samples on record.
The other 37 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 297 samples on record, detections range from September 24, 2003 to September 8, 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.

The most recent samples, result by result
The table below lists 101–110 of 297 samples, newest first — collected July 24, 2018 to July 25, 2018. The summary above covers all 297.
20 results from the 10 samples listed here: 11 detected, 9 not detected. Across the whole record it is 241 of 1,360. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
