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.

Scroll the table sideways for the dates.

No date range is applied: this list draws on every sample on record. Show the last two years only.

The most recent samples, result by result

The table below lists 21–30 of 226 samples, newest first — collected February 1, 2023 to March 26, 2024. The summary above covers all 226.

106 results from the 10 samples listed here: 4 detected, 102 not detected. Across the whole record it is 231 of 1,669. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
