Chemical and radiological sample results

MS0190008 , FCWA - Oldenburg

32 of the 71 analytes this system has been tested for have been detected at least once, across 261 samples on record.

The other 39 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 261 samples on record, detections range from September 15, 1993 to June 9, 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 FCWA - Oldenburg, 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 151–160 of 261 samples, newest first — collected July 26, 2007 to May 21, 2008. The summary above covers all 261.

49 results from the 10 samples listed here: 12 detected, 37 not detected. Across the whole record it is 418 of 969. 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 FCWA - Oldenburg, every result from 151 to 160 of 261 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
