The most recent samples, result by result

The table below lists 21–30 of 35 samples, newest first — collected August 11, 2025 to July 1, 2026. The summary above covers all 35.

53 results from the 10 samples listed here: 19 detected, 34 not detected. Across the whole record it is 706 of 2,359. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
