Chemical and radiological sample results

MS0360011 , City of Oxford

52 of the 122 analytes this system has been tested for have been detected at least once, across 1,194 samples on record.

The other 70 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 1,194 samples on record, detections range from July 30, 2002 to August 5, 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 City of Oxford, 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 791–800 of 1,194 samples, newest first — collected March 24, 2009 to April 27, 2009. The summary above covers all 1,194.

48 results from the 10 samples listed here: 16 detected, 32 not detected. Across the whole record it is 1,334 of 7,224. 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 City of Oxford, every result from 791 to 800 of 1,194 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
