Chemical and radiological sample results

MS0500007 , Central W/A-North Pearl River

21 of the 56 analytes this system has been tested for have been detected at least once, across 151 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 151 samples on record, detections range from October 8, 2003 to May 19, 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 Central W/A-North Pearl River, 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 141–150 of 151 samples, newest first — collected October 8, 2003 to November 16, 2004. The summary above covers all 151.

114 results from the 10 samples listed here: 9 detected, 105 not detected. Across the whole record it is 226 of 639. 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 Central W/A-North Pearl River, every result from 141 to 150 of 151 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
