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.

The most recent samples, result by result

The table below lists 161–170 of 288 samples, newest first — collected February 14, 2012 to June 20, 2012. The summary above covers all 288.

41 results from the 10 samples listed here: 20 detected, 21 not detected. Across the whole record it is 345 of 1,489. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

    0 mg/l This result is recorded as a detection, and the figure the agency wrote — "0" — is zero to the precision it was written to. Read the zero as "smaller than the written figure resolves", not as "none present".
