Chemical and radiological sample results
MS0110006 , Romola Water Association
34 of the 64 analytes this system has been tested for have been detected at least once, across 307 samples on record.
The other 30 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 307 samples on record, detections range from October 12, 1993 to December 29, 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 221–230 of 307 samples, newest first — collected April 25, 2007 to July 19, 2007. The summary above covers all 307.
24 results from the 10 samples listed here: 22 detected, 2 not detected. Across the whole record it is 497 of 1,206. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
