Chemical and radiological sample results
MS0220005 , Grenada Co W/S-Girl Scout
26 of the 57 analytes this system has been tested for have been detected at least once, across 341 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 341 samples on record, detections range from September 23, 1993 to September 30, 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.

The most recent samples, result by result
The table below lists 141–150 of 341 samples, newest first — collected March 29, 2016 to September 20, 2016. The summary above covers all 341.
22 results from the 10 samples listed here: 13 detected, 9 not detected. Across the whole record it is 256 of 2,178. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
