Chemical and radiological sample results
MS0340004 , Erata Water Association
33 of the 72 analytes this system has been tested for have been detected at least once, across 165 samples on record.
The other 39 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 165 samples on record, detections range from September 24, 2003 to July 27, 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 51–60 of 165 samples, newest first — collected June 15, 2020 to June 30, 2020. The summary above covers all 165.
23 results from the 10 samples listed here: 14 detected, 9 not detected. Across the whole record it is 188 of 722. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
