Chemical and radiological sample results

MS0340002 , Ellisville State School #1

35 of the 70 analytes this system has been tested for have been detected at least once, across 285 samples on record.

The other 35 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 285 samples on record, detections range from September 24, 2003 to August 3, 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.

Every analyte ever detected for Ellisville State School #1, 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 281–285 of 285 samples, newest first — collected June 6, 2002 to September 24, 2003. The summary above covers all 285.

67 results from the 5 samples listed here: 6 detected, 61 not detected. 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 Ellisville State School #1, every result from 281 to 285 of 285 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
