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.

Every analyte ever detected for Romola 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 131–140 of 307 samples, newest first — collected April 18, 2012 to July 10, 2012. The summary above covers all 307.

68 results from the 10 samples listed here: 7 detected, 61 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.

Units in this table

Combined Uranium is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

Chemical and radiological sample results for Romola Water Association, every result from 131 to 140 of 307 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
