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.

Every analyte ever detected for Kapalama Well, 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 11–18 of 18 samples, newest first — collected January 14, 2025 to May 20, 2025. The summary above covers all 18.

26 results from the 8 samples listed here: 4 detected, 22 not detected. 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 Kapalama Well, every result from 11 to 18 of 18 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
