Chemical and radiological sample results
MS0340010 , M & M Water Association
22 of the 58 analytes this system has been tested for have been detected at least once, across 565 samples on record.
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 565 samples on record, detections range from September 24, 2003 to December 15, 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 361–370 of 565 samples, newest first — collected February 13, 2013 to June 25, 2013. The summary above covers all 565.
40 results from the 10 samples listed here: 16 detected, 24 not detected. Across the whole record it is 469 of 4,571. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
