Chemical and radiological sample results

MS0240236 , Deerwood Utilities

33 of the 72 analytes this system has been tested for have been detected at least once, across 159 samples on record.

The other 39 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 159 samples on record, detections range from June 19, 1997 to February 11, 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 Deerwood Utilities, 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 81–90 of 159 samples, newest first — collected June 28, 2010 to October 12, 2011. The summary above covers all 159.

34 results from the 10 samples listed here: 7 detected, 27 not detected. Across the whole record it is 155 of 942. 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 Deerwood Utilities, every result from 81 to 90 of 159 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
