Chemical and radiological sample results
MS0230077 , Kapalama Well
4 of the 16 analytes this system has been tested for have been detected at least once, across 19 samples on record.
The other 12 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 19 samples on record, detections range from April 17, 2025 to October 7, 2025. These figures cover the whole record; the list of samples further down is narrowed.
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.
| Analyte | Kind | Detected in | First detected | Last detected |
|---|---|---|---|---|
| Barium 1010 | Inorganic Chemical | 3 of 3 results | Apr 17, 2025 | Oct 7, 2025 |
| Fluoride 1025 | Inorganic Chemical | 3 of 3 results | Apr 17, 2025 | Oct 7, 2025 |
| Chromium 1020 | Inorganic Chemical | 2 of 3 results | Apr 17, 2025 | Jul 17, 2025 |
| Nickel 1036 | Inorganic Chemical | 2 of 3 results | Apr 17, 2025 | Jul 17, 2025 |

The most recent samples, result by result
The table below lists 1–10 of 18 samples, newest first — collected July 17, 2025 to October 15, 2025. The summary above covers all 18.
38 results from the 10 samples listed here: 6 detected, 32 not detected. Across the whole record it is 10 of 67. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
