Chemical and radiological sample results
MS0210003 , Town of McLain
20 of the 58 analytes this system has been tested for have been detected at least once, across 321 samples on record.
The other 38 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 321 samples on record, detections range from November 17, 1993 to February 10, 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 41–50 of 321 samples, newest first — collected September 29, 2018 to February 10, 2020. The summary above covers all 321.
39 results from the 10 samples listed here: 17 detected, 22 not detected. Across the whole record it is 378 of 1,151. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
