Chemical and radiological sample results
MS0280001 , Town of Mayersville
29 of the 57 analytes this system has been tested for have been detected at least once, across 474 samples on record.
The other 28 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 474 samples on record, detections range from December 13, 1993 to December 3, 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 161–170 of 474 samples, newest first — collected July 17, 2014 to April 6, 2015. The summary above covers all 474.
38 results from the 10 samples listed here: 10 detected, 28 not detected. Across the whole record it is 617 of 2,714. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
