Chemical and radiological sample results

MS0340021 , City of Laurel

30 of the 61 analytes this system has been tested for have been detected at least once, across 670 samples on record.

The other 31 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 670 samples on record, detections range from July 30, 2002 to April 21, 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 City of Laurel, 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 361–370 of 670 samples, newest first — collected June 4, 2012 to September 11, 2012. The summary above covers all 670.

25 results from the 10 samples listed here: 4 detected, 21 not detected. Across the whole record it is 720 of 3,191. 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 Laurel, every result from 361 to 370 of 670 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
