Chemical and radiological sample results

MS0700006 , Mitchell Water Association

22 of the 57 analytes this system has been tested for have been detected at least once, across 203 samples on record.

The other 35 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 203 samples on record, detections range from October 29, 2003 to July 14, 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 Mitchell Water Association, 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 91–100 of 203 samples, newest first — collected September 8, 2014 to September 16, 2014. The summary above covers all 203.

39 results from the 10 samples listed here: 11 detected, 28 not detected. Across the whole record it is 188 of 1,020. 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 Mitchell Water Association, every result from 91 to 100 of 203 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
