Chemical and radiological sample results

MS0630037 , Truelight Redevelopment GRP #2

40 of the 74 analytes this system has been tested for have been detected at least once, across 510 samples on record.

The other 34 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 510 samples on record, detections range from October 22, 2003 to October 12, 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 Truelight Redevelopment GRP #2, 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 391–400 of 510 samples, newest first — collected July 26, 2010 to September 13, 2010. The summary above covers all 510.

65 results from the 10 samples listed here: 14 detected, 51 not detected. Across the whole record it is 836 of 2,203. 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 Truelight Redevelopment GRP #2, every result from 391 to 400 of 510 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
