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.

The most recent samples, result by result

The table below lists 1–10 of 18 samples, newest first — collected August 12, 2025 to July 30, 2026. The summary above covers all 18.

56 results from the 10 samples listed here: 17 detected, 39 not detected. Across the whole record it is 106 of 259. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

We withheld the location of 6 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.
