Chemical and radiological sample results

MS0610017 , City of Pearl

44 of the 77 analytes this system has been tested for have been detected at least once, across 1,062 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 1,062 samples on record, detections range from July 23, 2002 to June 23, 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 City of Pearl, 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 301–310 of 1,062 samples, newest first — collected July 24, 2019 to July 24, 2019. The summary above covers all 1,062.

20 results from the 10 samples listed here: 19 detected, 1 not detected. Across the whole record it is 1,321 of 5,383. 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 City of Pearl, every result from 301 to 310 of 1,062 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
