Chemical and radiological sample results
MS0220036 , Grenada Ind PK & Airport Water
37 of the 71 analytes this system has been tested for have been detected at least once, across 485 samples on record.
The other 34 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 485 samples on record, detections range from July 26, 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 241–250 of 485 samples, newest first — collected July 11, 2011 to July 18, 2011. The summary above covers all 485.
24 results from the 10 samples listed here: 21 detected, 3 not detected. Across the whole record it is 724 of 4,063. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
