Chemical and radiological sample results

MS0080009 , Town of Vaiden

38 of the 72 analytes this system has been tested for have been detected at least once, across 333 samples on record.

The other 34 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 333 samples on record, detections range from July 14, 1993 to November 20, 2025. These figures cover the whole record.

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 Town of Vaiden, 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 161–170 of 333 samples, newest first — collected September 22, 2011 to February 15, 2012. The summary above covers all 333.

49 results from the 10 samples listed here: 9 detected, 40 not detected. Across the whole record it is 420 of 1,328. 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 Town of Vaiden, every result from 161 to 170 of 333 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
