Chemical and radiological sample results

MS0070011 , Mt Comfort W/A-Mt Moriah

24 of the 57 analytes this system has been tested for have been detected at least once, across 333 samples on record.

The other 33 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 333 samples on record, detections range from September 21, 1993 to August 4, 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 Mt Comfort W/A-Mt Moriah, 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 51–60 of 333 samples, newest first — collected January 4, 2022 to June 21, 2022. The summary above covers all 333.

55 results from the 10 samples listed here: 7 detected, 48 not detected. Across the whole record it is 339 of 2,511. 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 Mt Comfort W/A-Mt Moriah, every result from 51 to 60 of 333 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
