Chemical and radiological sample results

MS0220003 , City of Grenada

42 of the 74 analytes this system has been tested for have been detected at least once, across 858 samples on record.

The other 32 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 858 samples on record, detections range from May 18, 1992 to March 26, 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 Grenada, 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 311–320 of 858 samples, newest first — collected July 20, 2015 to July 21, 2015. The summary above covers all 858.

20 results from the 10 samples listed here: 14 detected, 6 not detected. Across the whole record it is 1,027 of 4,405. 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 Grenada, every result from 311 to 320 of 858 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
