Chemical and radiological sample results

MS0330001 , Town of Bassfield

35 of the 72 analytes this system has been tested for have been detected at least once, across 168 samples on record.

The other 37 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 168 samples on record, detections range from September 29, 2003 to July 23, 2026. 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 Bassfield, 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 31–40 of 168 samples, newest first — collected June 8, 2021 to May 8, 2023. The summary above covers all 168.

42 results from the 10 samples listed here: 9 detected, 33 not detected. Across the whole record it is 258 of 710. 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 Bassfield, every result from 31 to 40 of 168 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
