Chemical and radiological sample results

MS0380009 , Toomsuba Water Association

43 of the 73 analytes this system has been tested for have been detected at least once, across 404 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 404 samples on record, detections range from September 29, 2003 to July 8, 2026. These figures cover the whole record; the list of samples further down is narrowed.

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.

Every analyte ever detected for Toomsuba Water Association, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 11–20 of 22 samples, newest first — collected February 11, 2025 to March 18, 2025. The summary above covers all 22.

76 results from the 10 samples listed here: 7 detected, 69 not detected. Across the whole record it is 427 of 2,499. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Toomsuba Water Association, every result from 11 to 20 of 22 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
